Bus End/Expansion TerminalsPX-901 $13.00
PX-902 $55.00
Bus End Terminal
The PX-901 (type 3) Bus End Terminal isinstalled at the end of a terminal assemblyand is required for proper I/O Bus communication.
The PX-902 (type 3) Bus Expansion EndTerminal enables expansion of terminalassemblies. The PX-902 is installed at the endof a PX-MOD or PX-TCP1 assembly andconnects the I/O Bus to a PX-903 BusExpansion Coupler Terminal via the RJ45port. No configuration is required.

System Installation and Removal
Removing Bus Couplerand Bus TerminalsA locking mechanism prevents individual unitsfrom being pulled off. For bus terminal removal,pull the orange DIN rail release tab firmly tounlatch the unit from the rail. If attached toother terminal units, slide unit forward untilreleased. For Bus Couplers with locking wheels,release the DIN rail locking wheel, then pullfirmly on DIN rail release tab.
Bus Coupler and BusTerminal InstallationBus Coupler Installation:1. Attach a Bus Coupler by snapping it onto
35mm DIN rail and securing it into positionusing the DIN rail locking wheel (whereapplicable) located on the left side of thecoupler.
Bus Terminal Installation:2. To add a bus terminal, insert unit onto right
side of Bus Coupler using the tongue andgroove at the top and bottom of the unit,pressing gently until it snaps onto the DINrail.
A proper connection cannot be made by slidingthe units together on the DIN rail. When correctly installed, no significant gap can beseen between the attached units. Bus connection is made through the six slide contacts located on the upper right side of theunits. Add up to 64 bus terminals per Bus Coupler, including a bus end terminal.
Insert unit using tongue and groove molded guide and press gently until it becomes firmly seated on DIN rail.
Align tab with molded guide
ntil raaiill.
Where applicable, rotate Locking Wheel to lock Bus Coupler

Installation ConsiderationsTerminal Dimensions andSpacing RequirementsUse the following diagrams to make surethe Protos X system can be installed in your application. Protos X terminals require35mm DIN rail for mounting; there are noorientation restrictions.
To ensure proper airflow for coolingpurposes, units should be spaced, at aminimum, as shown. It is also important tocheck the Protos X dimensions against theconditions required for your application.
See the Enclosures sectionfor an enclosure that may besuitable for your application

Protos XTM Five Basic Terminal Types
Type 1: This terminal passes the terminal power bus from the preced-ing terminal to the next terminal and therefore it must be mounted to a preceding terminal that passes bus power.
TYPE 1 TYPE 2 TYPE 3 TYPE 4 TYPE 5
Type 2: This terminal passes the terminal power bus and PE from the preceding terminal to the next termi-nal and therefore it must be preced-ed by a terminal that passes both terminal power bus and PE.
Type 3: This terminal does not pass the terminal power bus or PE and can be preceded by any terminal, however it will interruapt the terminal power bus and PE.
Type 4: This terminal requires exter-nal voltage connection and supplies the terminal power bus to terminals located to its right. The terminals to its right must support the same power bus of 120/230 VAC or 24VDC. This terminal will not pass terminal power or PE from any preceding terminals.
Type 5: This terminal is used to separate the termi-nal power bus and PE from other terminals and can mounted next to any termi-nal.
