Type CL6358 IS Discrete Pulse Count Input Isolating Barrier

Refer to the vendors instruction manual, MTL4000 Series Isolating ISinterface units, INM4000 and Appendix A of this manual for descriptionsand specifications of CL6350-Series barriers.

2.3 Determining the Quantity of Barriers and TerminationPanels for Your Application

The quantity and type of barriers, and termination panels, used for anapplication depend on the field signals and backup strategy.

CL6350-Series barriers for the following signals are available:

Analog Input (AI)

Analog Output (AO)

Smart Device Input (HART compatible)

Smart Device Output (HART compatible)

Discrete Input (DI)

Discrete Output (DO)

Pulse Count Input (PCI)

Types of backup strategies you may choose are:

Simplex (No backup)

1 for 1 Redundancy

1 for N Redundancy

First, determine the number of barriers your system requires. Each signalthat you want to connect to the PROVOX system from the hazardousarea must connect to a barrier.

All CL6350-Series barriers, except Type CL6356, accept one signal froma hazardous area. The Type CL6356 IS discrete input isolating barrieraccepts two input signals. Therefore, you need a barrier for each type ofsignal except a discrete input signal, for which you need one barrier forevery two signals.

Secondly, determine the number of termination panels required. Eachtermination panel can accept as many as 16 barriers carrying the samekind of signals, except for the Discrete Input termination panel, whichcan accept 32 signals (16 barriers with two inputs each.)

You cannot mix major barrier types (AI, AO, DI, DO, PCI, Smart Input,and Smart Output) on a termination panel. For example, you cannot put

2

Section 2 Product Overview 8


analog input barriers on the same panel as analog output barriers. Also,you cannot mix analog barriers and smart device barriers on the samepanel. However, you can put the Type CL6353 RTD and Type CL6354Thermocouple IS Input Isolating Barriers on the same panel becausethey are both analog input barriers, using the same analog I/O card.

Next, determine the number of I/O cards needed. To relate the numberof termination panels and barriers to the number of I/O cards, considerthe number and type of channels an I/O card can have. For example, anAnalog I/O card can have as many as 16 analog input channels or asmany as 8 analog output channels; a Discrete I/O card can have asmany as 16 discrete inputs, 16 discrete outputs, or 8 pulse count inputchannels. Do not mix input and output signals on the same card. Thesignals must be all input, or all output, or all pulse count input.

Table 2-1 shows the maximum number of input or output channelssupported by I/O cards. Knowing the number of channels you wish touse, up to the maximum, you can calculate the number and type of I/Ocards you need.

Table 2-1. Maximum Number of Channels Supported by I/O Cards

I/O Card Type MaximumNumber ofInputChannels

Type CL6721 Discrete I/O 16 (1) 16 8

Type CL6821 Analog I/O 16 8

Type CL6824 Analog Input 16

Type CL6825 Smart Input 16

Type CL6826 Smart Output 8

1. 16 input channels permits 32 input signals, two input signals per input barrier.

3 Installation

Before a system is installed, both physical planning and electricalplanning is required. This section provides information for both. Themanuals listed in Table 2-2 describe other pre-installation physical andelectrical planning.

3.1 Special Considerations

Appropriate precautions must be taken when using controlinstrumentation in areas where explosive gases or vapors are present.Precautions include special handling and special wiring.

Simply installing CL6340-Series termination panels and CL6350-Seriesbarriers does not necessarily provide a certifiable intrinsically safesystem. A certifiable system is a matter of design. To be certifiable, asystem must be designed and installed according to guidelines relevantto the country of installation and provided by the locally approvedcertifying authority.

Regulations governing intrinsic safety applications may preclude, ormake difficult, the mounting of CL6340-Series and CL6350-Seriesproducts in cabinets which contain other equipment, such as Control I/Otermination panels and MUX I/O files. Consult your certification authorityif combined mounting is essential.

Also see the vendors instruction manual, MTL4000 Series Isolating ISinterface units, INM4000, especially sections 3, 5, and 9 which describevarious precautions and warnings to heed prior to and during installation.

3.2 Planning the Physical Installation

The following subsections describe how to install the physical elementsof an intrinsically safe system.

3.2.1 I/O Cards and Card File

The I/O cards can be installed in any one of the 14 l/O card slots in theType CP6701 Control I/O Card File (Figure 3-1). An l/O card can beconfigured either as simplex, or for a redundant configuration, as the

3.2.4 Termination Cables

Termination cables connect the I/O cards to CL6340-Series terminationpanels. The cables can be a maximum of 200 feet (60 m) long. Fordetails on available cables and approved lengths, and a table which listshelpful cable installation tools, refer to Appendix B of this manual.

Compliance with electromagnetic compatibility legislation maybe compromised through the use of cables other than thosesupplied with the product.

Note ...

You must make sure that cable ducting does not become too full. With amaximum of ten panels possible on one side of a Type CP7043 cabinet,and a maximum of four cables for each term panel, there can bepotentially 40 cables in the ducting; however, the number of cablesshould not exceed 30.

The number of cables in the ducting of the Type CP7043System Cabinet should not exceed 30. Also, for a TypeCL6741, Type CL6841, or Type CL6842 cable interface panel,at least one rack-unit of space between the top of the panel andthe next panel above it must be left open. Cables are routed outof the top of the interface panels and require the space to makea proper radius bend.

Note ...

3.2.4.1 Cabling for Simplex I/O Cards

The number of cables and connections you require depends on the typeof I/O card and the type of redundancy strategy you are using. Forexample, assume you have a termination panel that contains 16Type CL6355 IS Analog Output Isolating Barriers which you areconnecting to two Analog cards (with 8 channels each).

To implement this example in a simplex system, you need two cables:one to connect each analog I/O card to the termination panel. (Thecables for connecting the analog cards to the termination panel aresupplied with the termination panel).

3.2.4.2 Cabling for 1 for 1 Redundant I/O Cards

When your system has 1 for 1 redundancy, every primary I/O card hasan associated backup I/O card. The following figures show examples ofeach type of I/O card and termination panel combination for 1 for 1redundancy. Although the following figures show the primary and backupI/O cards installed in the same card file, you can install them in separatefiles. The termination cables must not exceed 200 feet (60m).

3.2.4.3 Cabling 1 for N Configurations

Cabling for 1 for N redundancy (where N = 2 to 8 primary I/O cards)requires a Cable Interface Panel. The panel allows 1 backup I/O card toprovide redundancy for two to eight primary I/O cards. The CableInterface Panel is not required 1 for 1 redundancy.

The cable length between the primary I/O card and the termination panelmust not exceed 200 feet (60m). Also, the overall length of the cablesconnecting the I/O card, the Cable Interface Panel, and the terminationpanel must not exceed 200 feet (60m).

All termination panels and cable interface panels have either two or threeterminals labeled SHLD. One SHLD terminal on each panel must beconnected to the cabinet ground.

Cabinet mounting rails are grounded so that a short groundingstrap attached to the rail and a mounting bolt or grounding studon the back plate will provide adequate grounding.

Note ...

The following examples show some multiple card and termination panelcombinations. Not every possible redundancy combination is shown. Usethese examples to help you determine the correct wiring for yourredundancy strategy and card application.

3.2.5 Termination Cable Connectors

Termination cables longer than 20 feet (6m) are supplied with a spareD-shell connector. If the connector is too large to fit through a conduit orother limited access area, you can cut the cable and remove theconnector and then attach the spare connector after routing the cable.You should attach the spare connector to the end of the terminationcable according to the instructions provided with the connector. Refer toTable 3-1 for D-shell connector pin assignments (37-pin and 25-pin).

If you find it necessary to route the cable through a small area,cut the cable near the connector that you will attach to thetermination panel. An extra connector is provided with cables of50, 100, or 200 feet (15, 30, or 60m) for this purpose.

3.3 Planning the Electrical Installation

Each element in the installation has specific electrical requirements thatmust be considered. The following subsections provide planninginformation and electrical requirements for the elements.

The supplied wiring kit includes pre-terminated wires of the correctgauge and length to make the required connections when the panels aremounted in a Type CP7043 System Cabinet.

3.3.1 Termination Panel Power

Termination panels are supplied with nominal 24 Vdc power. Each panelis protected by a fuse. Screw terminals on the panels can accommodatetwo 14 AWG wires or a single 22 AWG wire.

Four screw terminals provide connections for primary and secondary +24Vdc and Power Supply Common.

The primary and secondary power terminals are labeled PRI +24 Vand SEC +24 Vdc, respectively.

Two redundant Power Supply Common terminals are labeled PSC.

Refer to Figure 2-1 to see the location of the power connector on thetermination panel. To connect power to the termination panels:

Step 1: Connect the positive wire from your 24Vdc supply to theterminal labeled PRI +24 V.

Step 2: If you have a secondary power supply, connect the positiveline to the terminal labeled SEC +24 Vdc.

If redundant power supplies are not used, place a jumperbetween the terminals labeled PRI +24V and SEC +24V.

Note ...

Step 3: Connect the screw terminal labeled PSC to the return, ornegative, line of the 24Vdc power supply.

Both simplex and redundant termination panels have two screws labeledSHLD that provide shield grounding for the termination cables. Use theshort black wire in the wiring kit to connect one of these terminals to thestud on the metal chassis. For more information about grounding, referto subsection 3.3.2.

3



3.3.2 Shield Grounding

A ground bar kit containing grounding terminals is optional and availablewhere field cable shield grounding is required at the termination panel.For detailed information on grounding, refer to the followingdocumentation:

AC and DC Power and Ground Wiring, PN1:003

Signal Wiring and Highway System Guidelines, PN1:004

Installing Type CP7010 Cabinets, PN4.4:CP7010

Installing Type CP7043 Cabinets, PN4.4:CP7043

If your system uses shield grounding, ground shields at one endonly. The other ends must be carefully insulated to preventpossible sparks or possible current flow between differentpotential ground points.

Warning ...

3.3.3 DC Grounding

The Power Supply Common (PSC) circuitry must be grounded through alocal ground bus (LGB) or a master ground bus (MGB) to the designatedsystem earth ground. For specific DC grounding information, refer to thedocumentation listed in subsection 3.3.2.

3.3.4 Connecting Field Wiring to Barriers

Hazardous area field wiring is connected to the BLUE terminal blocksthat plug into the front of the barrier. Either connect the wires using thescrews on the terminal block (maximum gauge 12 AWG) or by using anoptional push-in and crimp type block. Figure 3-19 shows the barrier andterminal connections. For detailed information about barrier field wiringconnections, refer to the specifications for the individual barriers inAppendix A and the vendors instruction manual, MTL4000 SeriesIsolating IS interface units.

A.3 Type CL6355 IS Analog Output Isolating Barrier

There are two types of Analog Output Isolating Barriers:

Conventional Analog Output

Smart Device Output

Use the conventional analog output barrier for applications which do nothave smart device capability. Use the smart device output barrier forapplications with smart digital valve controllers and digital transducers.

A.3.1 Conventional Analog Output Application

In an analog application, the Type CL6355 IS Analog Output IsolatingBarrier accepts a 4 to 20 mA signal from a safe-area controller to drive acurrent/pressure (I/P) converter or any other load up to 800 in ahazardous area. The output capability is 16 V at 20 mA, and the dropaccess across the input terminals is low (4 V). The input and outputcircuits float independently.

A.3.2 Smart Device Output Application

In a smart device application, the Type CL6355 IS Analog OutputIsolating Barrier accepts a 4 to 20 mA floating signal from a safe-areacontroller to drive a current/pressure (I/P) converter or any other floatingload up to 870 in a hazardous area. For HART compatible valvepositioners, the barrier also permits bi-directional transmission of digitalcommunication signals so that the smart device can be interrogatedeither from the controller or by a hand-held communicator (HHC).

Process controllers with a read-back facility can detect open or shortcircuits in the field wiring. If this occurs, the current taken into theterminals drops to a preset low value.

A.5.2 Relay Output

The Type CL6357 IS Discrete Output Isolating Barrier (Relay Output)enables either one or two separate IS circuits in a hazardous area to berelay-contact controlled by a single ON/OFF switch or logic signal in asafe area.

Applications include: the calibration of strain-gauge bridges, changingthe polarity (and thereby the tone) of a Linden IS Sounder, the testing ofIS fire alarms, and the transfer of safe-area signals into an annunciatorwith IS input terminals that are not segregated from each other.

The output-relay contacts are certified as a non-energy storing deviceand can be connected to any IS-circuit without further certification,provided that separate IS circuits are such that they would still remainsafe if connected together.
