Function
The DIRIS A-40 is a panel mounted power monitoring device compatible with TE/TR/iTR/TF smart current sensors, suitable for new or existing electrical installations.
The DIRIS A-40 has 3 native digital inputs and 2 digital outputs for additional versatility and includes RS485 Modbus RTU, Ethernet Modbus TCP and BACnet IP, and Profibus DP communication to report measurements to external management systems.

Advantages
Plug & Play
- Color-coded RJ12 cables for easy phase identification when wiring current sensors to the DIRIS A-40.
- 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.
Facilitated integration
The three current sensor technologies - solid-core, split-core and flexible Rogowski (TE, TR/iTR, TF) meet all the requirements for integrating new or existing applications.
Assisted configuration
A configuration wizard guides the user in a step by step process to configure the DIRIS A-40 directly from the screen. It also detects and corrects configuration errors which cuts the commissioning time in half and always delivers a reliable result.
Better than revenue grade
Compliant with the IEC 61557-12 standard, guaranteeing the quality and accuracy of the Power Meter:
- Class 0.2 for the meter alone.
- Class 0.5 for the global measurement chain (with TE/iTR/TF current sensors) from 2% to 120% of the rated current.
