Identify the Module Components
You received the following components with your order:
•
1756-OX8I module
•
Removable Terminal Block (RTB) door label
If you did not receive these components, contact your local
distributor Rockwell Automation sales office.
This module mounts in a 1756 chassis and uses a separately-ordered
RTB or a Bulletin 1492 Interface Module (IFM)
(1)
to connect all
field-side wiring. This module uses one of the following RTBs:
•
1756-TBCH 36 position Cage clamp RTB
•
1756-TBS6H 36 position Spring clamp RTB
Use an extended-depth cover (1756-TBE) for applications with heavy
gauge wiring or requiring additional routing space. When using an
IFM, consult the documentation that came with it to connect wiring.
Note the Power Requirements
This module receives power from the 1756 chassis power supply and
requires 2 sources of power from the ControlLogix backplane:
•
100mA at 5.1V dc
•
100mA at 24V dc
Add this current/power value (2.9W) to the requirements of all other
modules in the chassis to prevent overloading the power supply.Field
output supply power should be limited to 10KVA available short
circuit power.
(1)
The ControlLogix system has been agency certified using the only the ControlLogix RTBs (i.e.
1756-TBCH, 1756-TBNH 1756-TBSH and 1756-TBS6H). Any application that requires agency
certification of the ControlLogix system using other wiring termination methods may require
application specific approval by the certifying agency.
IMPORTANT
Before you install your module, you should:
•
install and ground a 1756 chassis and power supply.
•
order and receive an RTB or IFM, and its
components, for your application.
