Using electrical parameters means using several analog or digital single-function products such as ammeters, voltmeters or watt meters. DIRIS A20, with its four direct access keys and LCD displays, helps you use all the parameters in an LV installation.

These parameters can be centralized on a PC or PLC through an RS 485 link using JBUS/MODBUS protocol. The casing is designed so that the installer can easily fit the DIRIS A20 to the door of a cabinet. To facilitate and optimize the operator’s work, the DIRIS A20 uses one of the most functional principles for integrating communications or metering.

Simply fit a module to the rear of the casing to add a function. In addition, DIRIS A20 has a function for correcting connection errors .
