Recommended pull-up resistor versus supply voltage – External power

Discrete 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 7-2 for input voltage ranges.
