Strong Points

Function

The DIRIS B is a DIN-rail mounted power monitoring device compatible with TE/TR/iTR/TF smart current sensors, suitable for new or existing electrical installations.
The 4 independent RJ12 current inputs allow the DIRIS B to monitor 1 three-phase circuit and use a dedicated current sensor for the neutral, or 4 single-phase loads.
The DIRIS B has 2 native digital input for additional versatility and includes Modbus RTU serial communication to report measurements to external management systems.
Additional digital & analog input/output modules can extend the basic functional scope of the DIRIS B. An optional display can also be plugged to the meter for local visualization on panel doors.

Advantages

Plug & Play

- Color-coded RJ12 cables for easy phase identification when wiring current sensors to the DIRIS B.
- Automatic detection of current sensor type and rating.
- Using low-voltage mV current sensors, no shorting blocks are needed, they can be disconnected safely under load.

Better than revenue grade

- Class 0.2 DIRIS B accuracy according to ANSI C12.20.
- Class 0.5 system accuracy (DIRIS B + TE/iTR/TF current sensors) from 2% to 120% of rated current.

Multi-circuits

Four independent current sensor inputs allow you to configure multiple circuits in order to optimize the number of power meters per installation.

Versatile

The DIRIS B can be connected to:
- A remote DIRIS D-30 screen for local display of measurement data on the panel door.
- Optional digital or analog input modules, as well as temperature input modules.
- DIRIS Digiware M-50/M-70 gateways for centralization and communication of data via Ethernet. The DIRIS Digiware M-70 embeds WEBVIEW-M, a webserver for remote visualization of measurement data.
