Discrete output wiring
Discrete output (DO) wiring depends on whether you are wiring terminals 3 and 4 (Channel B) or
terminals 5 and 6 (Channel C), and also on whether you have configured the terminals for internal or
external power. The following diagrams are examples of proper wiring for these configurations:
