Chapter

Install Your FLEX I/O Frequency Input Module

Overview

This chapter provides you with pre-installation requirements and instructions

on how to install your FLEX I/O Frequency Input modules.

Before You Install

Your Module

Before installing your frequency input module in the FLEX I/O system, you

need to:

• calculate the power requirements of all modules in each FLEX I/O

system, and

• position the keyswitch on the terminal base.

Power Requirements

The wiring of the terminal base unit is determined by the current draw

through the terminal base. Make certain that the current draw does not

exceed 10 A.

ATTENTION

This FLEX I/O module does not receive primary operational power

from the backplane. 24V DC power must be applied to your module

before installation. If power is not applied, the module position may

appear to the adapter as an empty slot in your chassis.
