Installing the Analog Input Module
Chapter 3

We recommend either of two Allen-Bradley power supplies:
Power Supply (cat. no. 1770-P1) provides sufficient current for two
1771-IE input modules. This supply operates on either 120 or 220/240
VAC.
The Remote Power Supply (cat. no. 1778-P2) provides external power
for up to ten 1771-IE input modules. Do not use this supply for I/O
chassis power when powering analog modules. We recommend that you
order one or two power cables (cat. no. 1771-CF), and connect no more
than five 1771-IE input modules with a single power cable.
Power and common connections can be jumpered from one 1771-IE input
module to the next. Be careful to minimize the voltage drop in your
power connections.
WARNING: Maintain at least 5.0 VDC between the 5 VDC
terminal and common terminal measured at the wiring arm. A
lower voltage could cause intermittent operation resulting in
possible damage to equipment and personal injury.
Place your module in any I/O module slot except for the extreme left slot
of the I/O chassis. This slot is reserved for PC processors or adapter
modules. We recommend the following:
Do not put this input module in the same module group with a discrete
high density I/O module when using 2-slot addressing because this
input module uses both the input and output image tables for block
transfer. Two analog input modules, however, may be put in the
same module group.
Group analog input modules away from AC or high voltage DC I/O
modules to minimize electrical noise interference.
Once you designate a slot for your input module, you should not place
other types of modules in this slot. We recommend that you use the
keying bands, shipped with your I/O chassis, to accept only one type of
module in a designated I/O slot.
