Eastron SDM120M Series Energy Monitor

SDM120M Series

DIN Rail Mounted Metering Single Phase 45A MID (Multi-Function with Serial Communication)

SDM120M Series

The SDM120Modbus offers a low-cost solution to metering low-amp circuits (45A). The SDM120 range works directly connected to a maximum load 45A AC circuit.

The SDM120Modbus measures a vast range of parameters, including voltage, current, and power factor.

There are also 3 models available depending on the output required, this ranges from a just pulsed output (SDM120-Pulse), Modbus RTU (SDM120-Modbus), and MBus (SDM120-MBus). All SDM120 meters are housed in a 1-module DIN rail-mounted housing. They also come complete with sealable terminal covers to stop any tampering with the connections.
