The RI-F400 is part of the easywire® family of meters.

The easywire® system has been designed to save up to 90% installation time compared to a standard meter and current transformer installation.

They are a range of DIN 96 panel mounted multifunction energy meters. Suitable for monitoring energy consumption and many other electrical parameters in industrial and commercial applications. These meters may be used in single or three phase applications.

A high efficiency white backlit LCD display provides clear indication of measured values in all light conditions. Quick select push-buttons on the front of the meter allow the user fast access to the display page required.

The meter is available in two versions:-

  • With single pulse output.
  • With single pulse output and RS485 Modbus communication.
