12 ControlLogix™ Voltage/Current Input Module
Wire the Module
You can only connect wiring to your module through an RTB or IFM.
The example below shows how to wire the module.
Channel 0
Shield

Channel 3
2-Wire
Transmitter
1. Use the following chart when wiring your module in differential mode
NOTES:
This channel:
Channel 0
Channel 1
Channel 2
Channel 3
2. When operating in 4 channel, high speed mode, only use channels 0, 2, 4 and 6.
3. All terminals marked RTN are connected internally.
4. A 249 W current loop resistor is located between IN-x and i RTN-x terminals.
5. If multiple (+) or multiple (-) terminals are tied together, connect that tie point to a
terminal to maintain the module's accuracy.
