Schneider EM3500 Muti-channel Meter

The Schneider EM3500 series multi-channel meters can be installed on standard DIN rail or surface mounted as needed. Pulse output and phase alarms provide additional versatility. There are four unique models to fit your power monitoring needs.

The Modbus and BACnet output options offer added flexibility for system integration. The data logging capability (EM3555 and EM3560) protects data in the event of a power failure. Modbus, pulse output, and phase alarms are all provided to suit a wide variety of applications. Additional pulse inputs on EM3560 provide an easy way to incorporate simple flow sensors to track gas, water, steam, or other energy forms using a BACnet system in addition to full monitoring of electrical energy.
