Reyrolle 7SR105 Rho motor protection relay is a numerical protection relay intended for use in the motor protection applications. It provides a highly comprehensive functional software package with a range of integral application functions aimed at reducing installation, wiring, and engineering time.

The Reyrolle 7SR105 platform is a compact motor protection relay in a Non draw out case with 6BI/O’s, Serial interface, RTD inputs with Current based motor protection algorithms - simplest and comprehensive motor protection relay.

The device is housed in a 4U high, size 4 non drawn-out case and these relays provide protection, monitoring, instrumentation, and metering with integrated input and output logic, data logging and fault reports. Communication access to the relay functionality is via a front USB port for local PC connection or rear electrical RS485 port for remote connection.

A wide range of measured values can be viewed on the front LCD or remotely via the communications channel. The integrated control feature allows the safe operation of a motor and monitoring its start and stop operations.
