Energy Counter S501-40

The new SENECA energy counters for DIN rail mounting cover the most different application requirements for single-phase and threephase systems. Available with RS485 Modbus, M-BUS or Ethernet + webserver communication interfaces, the energy counters are compliant with MID (2004/22 / EC Directive) in class B with EN 50470 standard. Equipped with Wide backlighted LCD display for easy consultation of the values of energy and power, the counters also make avalilable the diagnostic function signaling polarity errors in the connection.
