Description
Configured for motor protection, control, measurement, and supervision in industrial process platforms, the ABB REM620 (REM620 Motor Protection Relay) provides direct physical/electrical execution. This dedicated hardware component manages medium- and large-sized asynchronous and synchronous motors using differential protection algorithms. Operating within ABB Relion 620 series frameworks, it processes RTD sensor inputs, mA analog signals, and IEC 61850 GOOSE communications for real-time fault clearance and overcurrent mitigation.

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling
The operational architecture of the ABB REM620 integrates advanced substation bus communication and scaling features:
- Profinet / EtherNet/IP Deterministic Networks: Supports IEC 61850 native GOOSE messaging alongside Ethernet-based topologies with zero-loss redundancy protocols (HSR and PRP), ensuring deterministic protection signal transmission across station buses.
- I/O Density Scaling: Accommodates high-density sensor inputs including direct RTD thermal monitoring, mA transducers, and optical arc sensors within a single withdrawable plug-in chassis.
- Firmware Flash Compatibility: Standardized memory configuration registers enable local HMI custom single-line diagram (SLD) adjustments and direct software compatibility via web-browser HMIs.
Frequently Asked Questions
Q: What redundancy protocols are natively supported on the REM620 Ethernet network interfaces?
A: The module natively supports High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) according to IEC 61850 Editions 1 and 2.
Q: How does the withdrawable design impact installation and testing constraints?
A: The withdrawable plug-in unit allows fast physical swapping and secondary testing while maintaining secondary current transformer shorting through automatically engaged contact blocks.
Field Installation Guidelines
When installing and commissioning the REM620 motor protection relay in switchgear panels, follow standard substation practices:
- De-energize all auxiliary supply voltages and isolate CT/VT secondary test circuits before inserting or removing the plug-in unit.
- Ground the relay enclosure earth terminal directly to the panel main earth bus using a short, low-impedance copper conductor.
- Route communication Ethernet cables and low-voltage analog signal wires in dedicated shielded ducts away from high-voltage primary conductors.
- Connect current transformer wiring through shorting test switches to ensure CT secondary loops remain closed during maintenance.
- Verify optical fiber cleanroom connections when implementing arc protection sensor runs to avoid signal attenuation.
