A-B 2094-BM01-S/B channel module

Block Mounting Genius I/O blocks are considered "open equipment" and therefore must be installed within a protective enclosure. They should be located in an area that is clean and free of airborne contaminants. There should be adequate cooling airflow. The block can be mounted right side up, or upside down. Leave at least 2 inches of space between blocks. Mount the block by drilling two screw or bolt holes for 8-32 hardware. Position the block so that the notches in the upper and lower flanges line up with the mounting holes. Mount the block using 8-32 screws. Use star washers to provide ground integrity

Wiring for a Bus Switching Module

If the block will be a BSM Controller, attach the Bus Switching Module to the block’s serial bus terminals. Attach the serial bus cables to the BSM as described in the Bus Switching Module datasheet. Wire the BSM like a load to circuit 1. Connect either BSM pigtail wire to terminal 6. For a DC Sink block, connect the other BSM wire to DC+. For a DC Source block, connect the other BSM wire to DC Power Connections Connect a DC power source to the DC+ terminal (5) and the return to the DC- terminal (22). Depending on the layout and current loads, positive and negative connections can be bussed and made by individual wires back to the block or power source.

Overtemperature Diagnostic (standard)

If the block’s internal temperature exceeds 100º C, the block sends an OVERTEMPERATURE message and turns off the circuit to protect its internal electronics. Failed Switch Diagnostic (standard) For an output, Failed Switch is reported if the circuit’s switch state is not the same as its commanded state. The block sends a FAILED SWITCH message identifying the failed circuit. The logic state of the circuit is set to OFF. If the output switch has failed shorted (or closed), current flow is not interrupted when the block forces the output state OFF. Action external to the block must be taken to remedy the problem.
