Description

Input Module, 120V AC, 8 Inputs:

Cover a wide electrical range

Densities range from 8...32 points

Isolated inputs or outputs, protected outputs, electronic fusing, or diagnostics available on some modules

Removal and Insertion Under Power (RIUP) lets you replace modules and make cable connections while the system is in operation

FLEX-I/O XT™ extreme environment modules are rated for -20...70 °C (-4....185 °F) and are compatible with the ControlLogix-XT™ extreme environment system. Contact NHP for further information.

Each I/O module requires a terminal base for connection points for I/O wiring

Wire directly from sensor to terminal base of the Flex™ I/O module and eliminate the terminal strip

Module Installation:

This module mounts on a 1794 terminal base unit.

1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position 8 as required for this type of module.

2. Make certain the flexbus connector (3) is pushed all the way to the left to connect with the neighboring terminal base/adapter. You cannot install the module unless the connector is fully extended.

3. Make sure that the pins on the bottom of the module are straight so they will align properly with the connector in the terminal base unit.

4. Position the module (4) with its alignment bar (5) aligned with the groove (6) on the terminal base.

5. Press firmly and evenly to seat the module in the terminal base unit. The module is seated when the latching mechanism (7) is locked into the module.

6. Repeat the above steps to install the next module in its terminal base unit.
