  • Voltage OUT connector for daisy chaining up to 32 meters from one supply


The RI-D380 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 accept inputs from four separate three phase, or twelve single phase easywire® current transformers while still utilising 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 two 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.
