1. Use the following chart when wiring your module in differential mode
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. If multiple (+) or multiple (-) terminals are tied together, connect that tie point to
terminal to maintain the module’s accuracy.
5. Terminals marked RTN and i RTN are not used for differential voltage wiring.

2. All terminals marked RTN are connected internally.
3. A 249 current loop resistor is located between IN-x and i RTN-x terminals.
4. If multiple (+) or multiple (-) terminals are tied together, connect that tie point to a RTN terminal to
maintain the module’s accuracy.
5. Place additional loop devices (e.g. strip chart recorders, etc.) at the A location in the current loop.
6. Do not connect more than two wires to any single terminal.
IMP ORTANT: When operating in 4 ch annel, high speed mo de, only use channels 0, 2, 4 and 6.
