The M570 PowerRelay is a complete single phase or three phase multifunction, RMS sensing, AC power transducer, providing up to 3 set point relay outputs, one energy relay and an RS485 communication port. Several of the parameters measured by PowerRelay can be assigned to the set point relays (marked ** below)The M570 is fully programmable through the communication port. Up to 3 fully isolated relay outputs are available. Most of the parameters measured can be assigned to the relays.(marked **)An optional pulsed output via a relay is offered. It can be assigned to W.h, Var.h (import or export), A.h or VA.h.
