Place the module in any I/O module slot of the I/O chassis except for the
extreme left slot. This slot is reserved for the programmable controllers or
adapter modules. In addition:
1. Do not put the module in the same module group as a discrete
high-density module with 2-slot addressing. However, other
single-slot modules may be placed in the same module group.
2. Do not put the module adjacent to AC or high voltage DC I/O
modules, to minimize electrical noise and temperature effects. Noise
can be minimized by grouping input and output modules together
within an I/O chassis.
See the user’s manual of any other intelligent I/O modules involved for
possible grouping limitations.
Module Keying Plastic keying bands, shipped with each I/O chassis
provide an easy method for keying I/O slots to accept only one type of
module. The module is slotted in two places on the edge of the rear circuit
board. The position of the keying bands on the backplane connector must
correspond to these slots to allow insertion of the module. You can key any
connector in an I/O chassis to receive this module except for the leftmost
connector reserved for processor or adapter modules. Place the keying
band between the following numbers labeled on the backplane connector:
between pins 2 and 4
between pins 6 and 8
You may change the positions of the bands if subsequent system design
and rewiring makes insertion of a different type of module necessary. Use
needle-nose pliers to insert or remove a keying band.
WARNING: To avoid injury to personnel and damage to
equipment, disconnect and lock out power from the processor
and system power supplies before wiring the m module.
Connections to/from I/O devices are made to the field wiring arm (catalog
no. 1771–WG shipped with the module. Attach the wiring arm to the pivot
bar at the bottom of the I/O chassis. It pivots upward and connects with the
module so you can install or remove the module without disconnecting the
wires.
