Control I/O Configuration
●
Run 240 Vac and 24 Vdc control wiring in separate conduit
●
Communication wire to be shielded

Notes
1
The above wiring demonstrates a SINK configuration. It is important that CMA and CMB are wired to ground (as shown by dashed line).
If a SOURCE configuration is desired, wire 24 V to CMA and CMB and close the inputs to ground. When using the +10 V for AI1, it is
important to wire AI1—ground (as shown by dashed line). If using +10 V for AI1 or AI2, terminals 3, 5, and 6 need to be jumpered together.

AI1+ and AI2+ support 10K potentiometer.
