Quad Load Three Phase easywire® Multifunction DIN Rail Energy Meter

The RI-D480 series are 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.

This series of meters contain four metering circuits in one case, and accepts inputs from four separate easywire® current transformers while still utilizing the same voltage reference.

These DIN rail mounted multifunction energy meters are suitable for monitoring energy consumption and many other electrical parameters in industrial and commercial applications. This series is particularly suited for use in multi-circuit metering boards in single or three phase applications.

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

The meter is available in one version:-
  • With RS485 Modbus communication (RJ12 - In and Out)
The unit is housed in a compact four module width housing suitable for DIN rail mounting.
