Supply voltage (Volts)

Note: When using a discrete output to drive a relay, choose external pull-up to limit current to less than 500 mA.

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 6-2for input voltage ranges.
