EM133  - TOU Smart Energy Meter

  • Comprehensive multi-functional energy meter, which provides a complete range of energy measurement and management. It measures the electrical energy and connects via digital inputs to water, gas or air condition meters. A built in relay output can be freely programmed to remotely disconnect the supply (using external contactors) or raising alarms. It has a 128kB memory for data logging.The information is displayed locally and is available via communication.

EM133-XM-AR - Advanced Residential

  • The AR model (Advanced Residential) also displays and stores present, previous and before previous day, week, month and quarter of all energy, hot and cold water and gas with customized pulse multiplication factors and labels. The AR model has an 8MB memory for data logging.
    Field installable add-on allows adding digital and analog I/Os to facilitate any control scheme (up to 14 digital inputs and 5 relay outputs).

Plug-In Modules

  • The EM132-133 modular approach enables users to assemble a system that meets their specific needs.
