S504C-6 3/4-wire 6A Three-phase Energy Meter with Communication Interface

S504C-6 is a compact 4-DIN module energy meter (MID certified versions also available) for energy measurement in industrial and civil environments, with integrated communication (RS485 Modbus, M-Bus or Ethernet). In addition to energy, the meter measures the main electrical parameters and makes them available on the integrated COM port. Totalizers and instantaneous powers are shown on the LCD display. The COM port allows managing the meter connected to a remote station. These data are transmitted over an RS485, M-Bus or Ethernet line depending on the instrument model.
