COM 4-20

Communication link to PLC/SCADA/

monitoring systems

Description

The COM 4-20 Output Module is intended for use with ONLY

the Model 777-AccuPower output power monitor. The module

will send a 4-20mA signal proportional to the output power.

It can also be used to send the input power by setting the

efficiency setting on the 777-AccuPower monitor to one.

This module allows communication to a PLC with an analog

input and no Modbus input.

Features

ꢀJ

Scalable 4-20mA output proportional to Hp or kW

ꢀJ

Signal can be used for displays, controllers, or PLCs
