PLC Outputs

Type How to Wire Notes
Relays / Sink type transistors generic out sink
Source type transistors generic out source Values may be inverted when using a PLC with source type outputs.
Fix this by inverting the actuators in the Driver Window for the board in use.

Resistors: We suggest values between 1 KΩ and 4.7 KΩ with a power rating of 0.5 W.

Resistors: We suggest values between 1 KΩ and 4.7 KΩ with a power rating of 0.5 W.

The DAQ board supports input voltages from 5 V to 50 V, and output voltages from 5 V to 40 V. If you are not sure how to properly wire the device, consult the Advantech manual.
