IEC protection relay REM620

safetyfor electric motorspanel-mount

REM620 is a dedicated motor management relay for the protection, control, measurement and supervision of medium- and large-sized asynchronous and synchronous motors in the manufacturing and process industry. Scope • Protection for larger asynchronous and synchronous motors Key benefits • Extensive protection and control functionality, either with sensors or conventional instrument transformers • Functional scalability and extensive possibilities to easily tailor configurations to application-specific requirements • Withdrawable plug-in unit design for swift installation and testing • Large graphical display showing customizable SLDs, accessible either locally or through an easy-to-use web-browser-based HMI • Extensive life-cycle services Key features • Extensive motor protection for medium- and large-sized asynchronous and synchronous motors requiring differential protection • Motor protection both during motor start-up and normal run, with protection and fault clearance in abnormal situations as well • Additionally extensive motor supervision capabilities via RTD and mA measurements and optionally arc protection • Supports native IEC 61850 Editions 1 and 2, including redundancy HSR and PRP, GOOSE messaging and IEC 61850-9-2 LE for less wiring and supervised communication • Supports Modbus, DNP3 and IEC 60870-5-103 communication protocols and different time synchronization methods, including high-accuracy time synchronization via IEEE 1588 V2 Precision Time Protocol
