8-Channel Contact Closure

DIN Fiber Link System

System Installation and Configuration Information

DescriptionThe RLH 8 Channel Contact Closure DIN Fiber Link system provides a transmission of up to eight independent contact closure signals over one optical fiber. The system comprises a transmitter module and a receiver module, each in a compact DIN mount housing.

The DIN mount is designed to be installed onto a standard T35 (35mm) DIN rail.

Transmitter module (TX)The Contact Closure Transmitter Unit provides the electrical/optical interface between the dry contact closure relay input and a fiber strand. The module is locally powered from a 24-56VDC source.

Note: In order to maintain high voltage isolation, Fiber Optic Link transmitter and receiver modules must be powered from separate power sources.

Receiver module (RX)The Contact Closure Receiver module provides the optical/electrical interface between the fiber strand and a normally-open relay contact output.

The receiver module is locally powered by a 24-56VDC source and provides LED indicators to display relay conditions, power, and fiber carrier receive.

USER GUIDE

RLH Industries, Inc.

General Safety PracticesThe equipment discussed in this document may require tools designed for the purpose being described. RLH recommends that service personnel be familiar with the correct handling and use of any installation equipment used, and follow all safety precautions including the use of protective personal equipment as required.

Caution - Severe Shock Hazard Never install during a lightning storm or where unsafe high voltages are present. Use caution when handling copper wiring and follow appropriate safety regulations.

Guidelines for handling terminated fiber cable

Do not bend fiber cable sharply. Use gradual and smooth bends to avoid damaging glass fiber. Keep dust caps on fiber optic connectors at all times when disconnected. Do not remove dust caps from unused fiber. Keep fiber ends and fiber connectors clean and free from dust, dirt and debris. Contamination will cause

signal loss. Do not touch fiber ends. Store excess fiber on housing spools or fiber spools at site

ApplicationsNetwork equipment in high voltage areas can be at risk due to Ground Potential Rise (GPR). A copper network cable referenced to a remote ground can become a path for high voltages during a ground fault. Placement of all-dielectric fiber optic cable (instead of copper) completely eliminates the presence of a remote ground, which dramatically increases safety of personnel and reliability of equipment.

By utilizing fiber optic cable, the Contact Closure DIN Fiber Link System provides absolute electrical isolation between both ends of the network. It is immune to EMI/RF interference, ground loops, and high voltage surges from lightning or ground faults, and is ideal in electrically noisy environments such as near large power sources, electrical motors, and radio communications equipment.

InstallationPrior to installation:

Check for shipping damage Check the contents to ensure correct model and fiber type Have a clean, dry installation environment ready Ensure that the fiber type at the site matches the system type

Required for installation:

24-56VDC (15mA@24VDC minimum) power source at the TX side 24-56VDC (65mA@24VDC minimum) power source at the RX side DIN rail for mounting Multimeter

Measure the DC voltage of the source power to ensure that it is 24-56VDC. All electrical and fiber optic connection are made directly onto the unit.

Connect fiber optic cableConnect fiber to the transmit and receive optical connectors on the top of the units. Fiber cable should always be routed loosely avoiding tight bends.

Connect contact wire pairsConnect the wire pair from each dry relay contact to the green screw-down terminals on the front of the units. The terminal blocks may be removed on the 8 channel system for ease of wiring by pulling the connector straight out. Be sure to fully seat the terminal block back into the connector when finished.

Refer to the connector diagram on the front of the unit for channel assignment. The channels are also identified on the connector blocks. Note which contact channel is being used.

Note: This system is dry contact only. Do not apply voltage to the contact terminals on the TX unit or the system may be damaged.

Connect alarm relay monitoring equipment wire pair to the alarm contact on the RX module. Use the NO or NC contact as required. To make wiring easier, the connector block may be removed by pulling straight up. Seat the connector fully into their sockets before operating the system.

Connect PowerConnect a 24-56VDC power source wiring to the screw-down terminals indicated as DC POWER. The power input is not polarity sensitive. The terminal unplugs from the module to make wiring easier.

Note: Connect a chassis ground wire to the screw on the top or bottom of the module housing to reduce the chance of damage from lightning or other high voltage events.

Troubleshooting If trouble is encountered, verify all copper and fiber connections, signal and voltage levels. If the alarm is on, double check the alarm jumper, fiber cable and connections, or TX side power source and connections.
