Protection Relays / DPR-400

DPR-400

Protection Relay

DPR-400 is a directional protection relay in standard
panel dimensions. Thanks to its low depth, it provides
space economy in panels.
The large color screen allows simultaneous display of
multiple measurements. The DPR-400 features dual
current measurement circuits. It is both a precise
analyzer and a 50xIn protection relay.

Through RS-485 and ethernet comports, the unit is
easily connected to Scada and automation systems.
Parameter adjustment is done through the USB or
ethernet ports.

The basic unit offers 4 digital inputs and 4 relay outputs.
Additional 16 inputs and 16 relay
outputs are optionally available
