
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—to 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+ use a 10k pot for 0–10 V.
