M560 Introduction

The M560 PowerSig is a complete single phase or three phase multifunction AC power transducer, providing up to 3 analogue outputs and the option of an RS485 communication port.

Up-to 3 fully isolated analogue outputs are available. Most of the M560's measurements can be assigned to the outputs which can be either DC mA or DC volts. If PowerSig is purchased without the option of RS485 the user must specify which measurement is required for each output when ordering.

The M560 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)

An option of pulsed output via a relay is offered. The pulsed output can be assigned to W.h, Var.h (import or export), A.h or VA.h.

Using the RS485 port and Modbus protocol, all measured quantities can be obtained, the system's parameters can be set up, important data can be saved to computer and the order of the Modbus registers themselves can be changed.
