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.
