The DIRIS B series is a modular power monitoring device that communicates via RS485. This device has 4 independent RJ12 current input ports, allowing management of multiple types and quantities of circuits: for example, 4 single-phase loads or 1 three-phase load+1 single-phase load.

DIRIS B is connected to current transformers (1) (RJ12 connection): closed TE, open close TR, and flexible TF current transformers.
