Using your module in the ControlLogix System
Place your module in any slot of a ControlLogix modular, or modular
expansion chassis.
An analog I/O module translates an analog signal into, or from, a
corresponding digital representation which controllers can easily operate
on for control purposes.
A ControlLogix I/O module mounts in a ControlLogix chassis and uses a
Removable Terminal Block (RTB) to connect all field-side wiring.
Before you install and use your module you should have already:
· installed and grounded a 1756 chassis and power supply.
· ordered and received an RTB for your application.
Important: RTBs are not included with your module purchase.
Specify Allen Bradley Part Number:
1756-TBCH - 36 position screw terminals
1756-TBS6H - 36 position press terminals
Module Installation
and Removal
When installing the module in a chassis, it is not necessary to remove the
terminal blocks from the module. However, if the terminal blocks are
removed, use the write-on label located on the side of the terminal blocks
to identify the module location and type.
