Product Description

The Reyrolle 7SR158 Argus voltage and frequency relays are numerical, multifunctional devices, with functionality designed for connection to voltage transformers. The voltage and frequency functionality is supplemented by data storage, instrumentation, user configurable logic and data communication features. A menu based user friendly interface provides local access to relay settings, instruments and operational data. The fascia also benefits from 9 user configurable, tri-coloured LEDs and a USB port for PC access.
The key functions provided include 27/59 -Under and Over voltage, 81 -Under and Over frequency, 78 -Voltage vector shift and 81R -Rate of change of frequency.

Relays have three voltage inputs, six binary inputs and eight binary outputs and are housed in a size E4 case. Programmable logic is provided to allow the optimal configuration of relay functionality. A rear electrical RS485 port is provided for SCADA connection using either IEC60870-5-103, DNP3.0 or MODBUS RTU protocol.
