Sensor type and Sensor unit for No of Phases question - E1.20 RDM (Remote Device Management) Protocol Forums

berntd · October 1st, 2009

Hello again,

Here is another one,
What sensor type and units should I use for the number of active mains phases?

I can't see anything obviously suitable by just looking at Tables A-12/A-13.

Is it a device where you expect the number of phases to change on a regular basis (like a dimmer pack that can be wired for single phase or three phase)?

You could have multiple voltage sensors, and report the voltage for each input phase separately.

Or, SENS_OTHER and a Manufacturer-Specific Unit along with a well-written text string should work for most controllers.
