Installing the Input Module

Publication 1771Ć6.5.115 - February 1999

Before installing your input module in the I/O chassis:

You need to:

As described under:

Calculate the power requirements of all

modules in each chassis.

Power Requirements, page 2-2.

Determine where to place the module in the I/O

chassis.

Module Location in the I/O Chassis,

page 2-3.

Set the Series A/B simulation jumper.

Setting the A/B Simulation Jumper,

page 2-5

Key the backplane connector in the I/O chassis. Module Keying, page 2-6.

Make connections to the wiring arm.

Wiring Your Input Module, page 2-8

and Grounding, page 2-13.

Important: The 1771-IFE module is shipped from the factory set

for voltage mode and Series C applications. Refer to
“Setting the Configuration Plugs on the Module”on
page 2–3 for other combinations of current and
voltage inputs and “Setting the Series A/B Simulation
Jumper” on page 2–5.

Electrostatic discharge can damage semiconductor devices inside this
module if you touch backplane connector pins. Guard against
electrostatic damage by observing the following precautions:

!

ATTENTION: Electrostatic discharge can degrade
performance or cause permanent damage. Handle the
module as stated below.

Wear an approved wrist strap grounding device, or touch a
grounded object to rid yourself of electrostatic charge before
handling the module.

Handle the module from the front, away from the backplane
connector. Do not touch backplane connector pins.

Keep the module in its static-shield bag when not in use.

Your module receives its power through the 1771 I/O power supply.
The module requires 500mA from the backplane.

Add this current to the requirements of all other modules in the I/O
chassis to prevent overloading the chassis backplane and/or
backplane power supply.
