PI-DIN Interface Protection Unit
The PI-DIN interface protection device is a monitoring relay especially designed for the connection of renewable energy production plants to the public utility. Voltage and frequency are constantly monitored and measured. In case the measured values are out of the Norm specified ranges the grid feeding is interrupted by opening the main breaker. Feeding is restored as soon as the grid values return to specified ranges.
This specific device is equipped with 2 relay outputs: one for the control of the main breaker ("DDI") and the second one for the backup breaker ("Rincalzo") which is mandatory on plants above 20kWp according to CEI 0-21:2019-04 Norm.
The PI-DIN logs all the events with registration of date, time and type of the last 10 events. The data can be remotely read in real time by means of the RS 485 communication line. The line can also be used for remote configuration, simplifying the operation.
