REM620 is a dedicated motor management relay perfectly aligned for the protection, control, measurement and supervision of medium-sized and large asynchronous and synchronous motors requiring also differential protection in the manufacturing and process industry.
REM620 is a member of ABB’s Relion® protection and control product family and its 620 series. The 620 series relays are characterized by their functional scalability and withdrawable-unit design.
The 620 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.
The 620 series relays support a range of communication protocols including IEC 61850 with Edition 2 support, process bus according to IEC 61850-9-2 LE, IEC 60870-5-103, Modbus® and DNP3. Profibus DPV1 communication protocol is supported by using the protocol converter SPA-ZC 302.
