Installing the RTD Input

Module

This chapter gives you information on:

• calculating the chassis power requirement

• choosing the module’s location in the I/O chassis

• keying a chassis slot for your module

• wiring the input module’s field wiring arm

• installing the input module

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

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 2-2.

Key the backplane connector in the I/O chassis. Module Keying, page 2-3.

Make connections to the wiring arm and ground

your module.

Wiring Your Input Module, page 2-4, and

Grounding, page 2-6.

The RTD input module is sensitive to electrostatic discharge.

ATTENTION: Electrostatic discharge can damage

integrated circuits or semiconductors if you touch

backplane connector pins. Follow these guidelines

when you handle the module:

• Touch a grounded object to discharge static potential

• Wear an approved wrist-strap grounding device

• Do not touch the backplane connector or

connector pins

• Do not touch circuit components inside the module

• If available, use a static-safe work station

• When not in use, keep the module in its

static-shield bag

This product has the CE mark and is approved for installation within

the European Union and EEA regions. It has been designed and

tested to meet the following directives.
