The DIRIS B-30 is a measuring device in a modular format that communicates wirelessly or RS485. The 4, RJ12 independent current inputs of the device allow it to manage several types and numbers of circuits :for example, 4 single-phase loads or 1 three-phase load + 1 single-phase load. The DIRIS B-30 is connected to current sensors (RJ12 connection) that are suitable for all types of installation: solid TE, split-core TR, and flexible TF current sensors.
