ABB REM620_F Relion 620 Series Motor Protection and Control IED
Configured for motor differential protection and thermal overload protection in heavy-duty motor drives, the ABB REM620_F (REM620 Motor Protection and Control IED) provides direct physical/electrical execution. The instrument captures multi-channel current, voltage, and thermal inputs via standard sensor arrays, executing high-speed contactor and breaker control commands while recording operational disturbances on the localized backplane bus architecture.

Industrial Control & Network Determinism Profiles
The motor protection unit integrates seamlessly within Profinet / EtherNet/IP deterministic networks and digital substations utilizing native IEC 61850 station-bus infrastructure. Dual-channel Ethernet ports enable execution of Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR) data topologies to maintain communication uptime during single-path physical layer failures. The dedicated high-speed GOOSE messaging channels handle interlocking and horizontal trip distribution with transmission times below 1 ms, utilizing isolated I/O density scaling options to interface field contactors directly without requiring external intermediate relay hardware.
Frequently Asked Questions
Q: How does the network interface handle concurrent industrial protocols without dropping frames?
A: The onboard communication card isolates specific process bus functions like IEC 61850-9-2 sampled values from station-bus protocols like Modbus and DNP3, ensuring hardware processing bandwidth handles trip commands with sub-millisecond priority.
Q: What mechanisms protect the internal firmware flash compatibility during hot swap or draw-out operations?
A: The draw-out housing incorporates automated short-circuiting CT blocks that secure current transformer loops before mechanical isolation of the internal chassis, protecting flash memory chips from inductive voltage peaks.
Q: Can the RTD inputs operate over extended distances without degrading accuracy?
A: The hardware interfaces up to 14 RTD paths using dedicated internal analog filtering and compensation coefficients that correct for line resistance variations on 3-wire or 4-wire measurement loops.
Field Installation Guidelines
Install the draw-out unit within a standard cutout panel or rack adapter matrix, ensuring all mechanical guides align before locking the assembly into position. Connect all incoming current and voltage transformer secondary circuits to the rear compression terminal assembly, verifying absolute polarity mapping against the electrical drawing set.
Technicians must route low-level signal paths—including the 14 RTD sensor runs and internal 5 mA inputs—through dedicated grounded metallic wireways to prevent induction from adjacent high-voltage motor supply feeds. Ground the main enclosure frame to the station earth bar using a heavy copper conductor with a clean, unpainted contact surface. Verify network continuity by attaching the redundant fiber or copper Ethernet paths to the PRP/HSR network switches before energizing the master feeder breaker.
