REM615 is a dedicated motor IED perfectly aligned for the protection, control, measurement and supervision of asynchronous motors in manufacturing and process industry. Typically, REM615 is used with circuit-breaker or contactor controlled HV motors, and contactor controlled medium sized and large LV motors in a variety of drives. REM615 is available in three standard configurations including all the basic motor protection functions, voltage protection functions and power and energy measurements. Local or remote start/stop control of the motor is also facilitated.
REM615 features genuine support for the IEC 61850 standard for communication in substations, including IEC 61850-9-2 LE, and also for Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR) protocols. The IED also supports DNP3, IEC 60870-5-103 and Modbus® protocols. The Profibus DPV1 protocol is supported by using of the protocol adapter SPA-ZC 302.
For a redundant Ethernet solution REM615 offers an optional communication module providing Ethernet network interfaces. The redundant Ethernet solution can be built on the Ethernet based IEC 61850, Modbus® and DNP3 protocols.
The implementation of the IEC 61850 standard in REM615 covers both vertical and horizontal communication, including GOOSE messaging with binary and analog signals and parameter setting according to IEC 61850-8-1. REM615 also supports process bus with sampled values of analog phase voltages. With this functionality the galvanic interpanel wiring can be replaced with Ethernet communication. The measured values are transferred as sampled values using the IEC 61850-9-2LE protocol.
REM615 is a member of ABB’s Relion® product family and its 615 series.
