and there are 2 wires to connect. I cannot locate any wiring instructions for this switch, but my non-electrical mind says something like the SNAP ICD5-SW, which “supplies 15 volts of power to an external dry contact switch and senses switch closure” would work. I’ve got a newly freed up Rio to use and am wondering if I supply this switch with 24V (from the Rio or elsewhere), then can I use the Rio to detect the switch closure? FWIW, I have a 24VDC power supply powering the Rio. If the answer is yes, which Input on the Rio would I use?
Its very simple.
You just wire the two wires from the switch to the channel input terminals on the RIO, select the type, hit save and you are up and running.
BTW, all these screen shots came from a RIO.
Just dig your way into the I/O Reference menu from here;
Perfect, thank you. I will hook this all up tomorrow and report back. I have a good comfort level getting the data in & out using Node-RED. This particular application is a heated tank with two solenoids feeding fluids into the tank, two float switches and two Type K thermocouples. I think I can do it all with one Rio.
