The M570 is a fully programmable three phase power transducer with an isolated RS485 based communication port supporting a subset of Modicon’s Modbus protocol.
The M570 houses three monitoring relays and an optional, independent energy relay.

The three relays installed in the M570 can have up to eight conditions attached (shared between them), creating a very flexible monitoring system.

Its accuracy is class 0.25% for voltage and current input signals down to 10% Un and 10% In, 0.3% for power measurements and 1% of reading for energy measurements.IEC1036, 50-60Hz.

The M570 measures Voltages, Currents, Import/Export Power (W, VAr, VA), True Power Factor, Frequency, Import/Export Demands(Wd, VArd, VAd, Ad) and Import/Export Energy (W.h, VAr.h, VA.h, and A.h, pulsed through a relay)

All measured quantities can be extracted from the transducer, the system's parameters can be set up remotely, important data can be saved to computer and the order of the Modbus registers themselves can be changed.
