Powermonitor

In search of single phase;phase monitor for 240v with modbus comms. Just need to monitor voltage and amps. Or I like to monitor voltage with a AB micro800 or 1100, any ideas? I can use Analog CT for amps.

Hi

The ABB electricity meters are good for this.

Has Modbus and monitors I/A and power.

Schneider Electric makes them:

Wago has input modules for power monitoring, can do voltage, amps, active, reactive, apparent power, cosinus phi etc. Used in conjunction with transformers or Rogowski coils.

Wago modules 750-493, 750-494 or 750-495 depending on how you get your input (transformers, Rogowski coils). If used through Modbus/TCP then you would additionally need a 750-352 (fieldbus coupler for remote I/O over modbus/TCP) and an end module 750-600. The modules are designed for three phase and when used with remote I/O costs add up so this may not be cost effective for you, especially if you only measure a single phase.
