Factory-Set Control Terminal Functions
I/O Connection
Notes:
-
The above wiring demonstrates a SINK configuration. It is important that CMA is wired to ground (as shown by
dashed line). If a SOURCE configuration is desired, wire 24 V to CMA 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).
-
AI1+ support 10 K potentiometer.
