Industrial Automation Card - Node-Red

[brandon_bern]

Hey All,

I'm working on setting up a Node-Red flow that monitors a 4-20ma input and also controls a few indicator lights.

I'm not sure what the msg: payload needs to be to turn the output on or off when using the IND OD Out node.

I'm pretty new to this world so any information is greatly appreciated. Thanks in advance!

The node updates the open drain PWM filling factor, so the payload must be a number between 0 and 100.

Alex.

Thanks Alex, That worked! When I pass a payload value of 100 to the IND OD Out node the light turns on.
