NOTES:
1. Use the table when wiring your module in differential mode
2. All terminals marked RTN are connected internally.
3. If multiple (+) or multiple (-) terminals are tied together, connect that tie point to a RTN terminal
to maintain the module’s accuracy.
4. Terminals marked RTN or iRTN are not used for differential voltage wiring.
5. Do not connect more than two wires to any single terminal.
IMPORTANT: When operating in four channel, high-speed mode, only use channels 0, 2, 4 and 6.
