ABB 1MRK002133-ACR02 Protection Relay for REL Series

ABB 1MRK002133-ACR02 Protection Relay for REL Series

The ABB 1MRK002133-ACR02 is a dedicated protection relay module engineered for seamless deployment within ABB’s REL series substation automation architecture. Designed to serve as a critical node in layered protection schemes, this module ensures coordinated fault detection, signal discrimination, and trip command execution across medium- and high-voltage distribution networks. Its role within the broader control system hierarchy extends beyond standalone protection—it functions as an integral element linking bay-level control, station-level SCADA communication, and process-bus interfacing within IEC 61850-compliant substations.

System Compatibility Notes

Within a fully coordinated substation protection and control architecture, the 1MRK002133-ACR02 operates alongside several complementary ABB modules to deliver comprehensive system coverage. At the bay level, it interfaces directly with the REL670 line distance protection relay, sharing trip signals and breaker failure logic through hardwired connections and IEC 61850 GOOSE messaging. The REB670 busbar protection unit coordinates zone-selective interlocking with this module, ensuring that upstream and downstream fault isolation occurs within deterministic time frames.

For station-level integration, the COM600 station automation gateway aggregates data from the 1MRK002133-ACR02 and peer protection IEDs, presenting unified event logs, disturbance records, and real-time measurements to the network control center. The RTU560 remote terminal unit provides an alternative communication path for legacy SCADA protocols, bridging IEC 60870-5-101/104 networks with modern Ethernet-based station buses.

Power supply redundancy is maintained through the ABB CP-E 24/10.0 DIN-rail power supply modules, which deliver regulated DC voltage to all bay-level electronics including the 1MRK002133-ACR02. In configurations requiring extended I/O, the REX640 modular protection and control platform can be deployed in adjacent bays, sharing protection coordination settings and communication infrastructure with this relay module.

Signal acquisition from instrument transformers is conditioned through the SMAI function blocks within the relay, while the ABB FOCS fiber-optic current sensor system provides non-conventional measurement alternatives in high-voltage applications. The RIO600 remote I/O unit extends binary and analog signal reach to field devices located at considerable distances from the relay panel, reducing copper cabling requirements and improving electromagnetic immunity.

Human-machine interface access is facilitated through the ABB Relion HMI local panel, enabling on-site parameter adjustment, event browsing, and diagnostic review without requiring a laptop connection. For centralized engineering, the PCM600 Protection and Control IED Manager software provides configuration, parameterization, and disturbance analysis across all REL series devices in the station, including the 1MRK002133-ACR02.

Industrial Application Notes

The 1MRK002133-ACR02 finds its primary application in electrical utility substations, industrial power distribution centers, and renewable energy collection points where layered protection coordination is essential. In a typical 132kV/33kV transmission substation, this module occupies the bay-level protection tier, executing distance protection, overcurrent backup, and breaker failure functions that must coordinate with both upstream transmission protection and downstream feeder relays.

In industrial environments such as petrochemical complexes, steel manufacturing plants, and mining operations, the module integrates into medium-voltage switchgear lineups where motor protection, transformer differential protection, and bus-tie interlocking demand precise coordination. The IEC 61850 communication capability enables horizontal GOOSE messaging between bays, eliminating traditional hardwired interlocking and reducing commissioning time significantly.

Water treatment facilities and municipal power distribution networks benefit from the module’s ability to participate in automated fault location, isolation, and supply restoration (FLISR) schemes. When deployed alongside distribution automation controllers, the 1MRK002133-ACR02 contributes protection intelligence to self-healing grid architectures that minimize customer interruption duration.

For renewable energy applications, wind farm collection substations and solar plant medium-voltage networks utilize this relay module for feeder protection and anti-islanding detection, ensuring grid code compliance while maintaining generation availability. The module’s flexible communication stack supports integration with both traditional SCADA systems and modern distributed energy resource management platforms.

Long-term maintenance is simplified through built-in self-supervision, contact wear monitoring, and predictive diagnostics accessible through the station automation system. Spare parts availability and standardized rack mounting ensure that replacement or upgrade activities can be completed during scheduled outages with minimal system reconfiguration.

Product Compatibility FAQ

Q1: How does the 1MRK002133-ACR02 integrate with existing REL series protection schemes?
The module is designed for direct compatibility with ABB’s REL670, REB670, and RET670 protection relays through standardized IEC 61850 communication profiles and common engineering tools (PCM600). Configuration templates ensure consistent protection coordination settings across all bay-level devices, and the module supports both horizontal GOOSE peer-to-peer messaging and vertical MMS client-server reporting to station-level systems.

Q2: What are the power supply and environmental requirements for reliable long-term operation?
The module operates on 48–250 V DC auxiliary supply with built-in voltage supervision. For installations in harsh environments, IEC 60255 compliance ensures operation across -25°C to +55°C ambient temperature ranges. Redundant power supply configurations using dual CP-E series modules are recommended for critical protection applications where supply interruption cannot be tolerated.

Q3: What warranty and support coverage applies to this module?
This unit is supplied with a warranty terms confirmed during quotation covering manufacturing defects and functional non-conformance. Technical support includes commissioning guidance, firmware compatibility verification, and integration assistance for IEC 61850 system configuration. system integration support ensures the module is properly configured within the broader station protection and control architecture before energization.
