I/O Bus
These modules are intended for installation within the UL Listed enclosure
model UL-ENCL for UL 294 and UL 1076.
I/O Modules connect in the following configurations:
Direct Connect
Direct Connect
Do not remotely ground any part of the input sensor wiring.
Max. Number of I/O Modules
Number of modules is limited to 32 per CPU but may
be reduced due to the capacity of the Power Supply**

Remote grounds connected to the return terminal could make
the system operate incorrectly or damage the equipment.
Power Supply
The signal return is not true earth ground. It is an electronic
reference point necessary to interpret the sensor properly.

For reliable operation, follow these wiring guidelines:
· Never lay wires across the surface of a printed circuit board.
· Wires should never be within 1 in. or 25 mm of any component
on a printed circuit board.

· Use shielded wire.
· Terminate the shield of the wires at one end of the run
onlypreferably at the end where your I/O module is located.
· Be careful when stripping wire not to drop small pieces of wire
inside the cabinet.
· Dont run your wiring in the same conduit with AC power.
· Dont run your input wiring in the same conduit with your
output wiring.
