6.6Discrete input wiring
Discrete input wiring depends on whether you have configured terminals 5 and 6 (Channel C) for internal or external power. The following diagrams are examples of proper wiring for these configurations.
If external power is configured, power may be supplied by a PLC or other device, or by direct DC input. See Table
