Identify the Module Components
You received the following components with your order:
1756-IF16 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 chasis power supply and
requires 2 sources of power from the backplane:
150mA at 5.1V dc
65mA at 24V dc
Add this current/power value (2.33W) to the requirements of all other
modules in the chassis to prevent overloading the power supply.
Number of Inputs 16 single ended, 8 differential or 4 differential (high speed)
Module Location 1756 ControlLogix Chassis
Backplane Current 150mA @ 5.1V dc & 65mA @ 24V dc (2.33W)
