Notes
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+ block that it can support 10K potentiometer.
