Installing Your Module
This chapter describes the procedures for installing your remote I/O
adapter module. These include:
•
power requirements
•
module location and keying
•
setting configuration plugs
•
setting the module switches
•
setting the I/O chassis switches (backplane and
•
setting the I/O chassis power supply configuration plug
•
wiring the field wiring arm
•
installing the terminator resistor
•
compatibility of products
•
installing the module
The remote I/O adapter module requires a backplane current of 1.0A
at 5V dc. Remember to add this amount to other current
requirements for your remote I/O chassis.
The remote I/O adapter module must be installed in the leftmost slot
of the I/O chassis.
The I/O chassis backplane connectors are keyed to accept only one
type of module. This prevents accidental insertion of other modules
in the wrong module slot. Key the backplane connectors (Figure 2.1)
for the adapter module as follows:
•
upper connector: between 54 and 56
•
lower connector: between 16 and 18
