ABB 1MRK000195-AAR02 Industrial Network Interface for RED Series Systems: Precision Data Links for Smart Factory Protection Networks

The ABB 1MRK000195-AAR02 is a high-performance protection relay board engineered for the ABB RED Series platform, delivering robust IEC 61850 communication capabilities across complex industrial power protection networks. Designed for mission-critical substation automation and smart factory environments, this board serves as the central communication node between field protection devices, PLC controllers, SCADA supervisory systems, and upper-level management platforms. With native support for IEC 61850 GOOSE messaging and MMS protocol stacks, the 1MRK000195-AAR02 enables real-time data exchange, deterministic trip signal transmission, and seamless integration into modern digital substations and industrial automation architectures.

In today’s intelligent manufacturing and power distribution environments, the ability to bridge legacy field devices with modern Ethernet-based control networks is no longer optional — it is a fundamental requirement. The ABB 1MRK000195-AAR02 addresses this need directly, acting as a protocol gateway and communication backbone within the RED Series relay family, ensuring that protection events, fault records, and operational status data flow without interruption from the field level to the control room.

Compatibility & Integration Notes

Connected Automation Data Flow

The ABB 1MRK000195-AAR02 sits at the heart of a layered industrial communication architecture. At the field level, current transformers (CTs), voltage transformers (VTs), and digital sensors feed analog and digital signals into the RED Series relay platform. The 1MRK000195-AAR02 board processes these inputs and converts them into structured IEC 61850 data objects, which are then transmitted across the station bus to peer protection relays, bay controllers, and merging units.

Within a typical substation automation system, the 1MRK000195-AAR02 communicates directly with the ABB REF615 feeder protection relay and the ABB RET615 transformer protection relay via GOOSE messaging, enabling sub-millisecond trip signal exchange without relying on hardwired copper connections. This dramatically reduces wiring complexity while improving response time and diagnostic transparency. The board also interfaces with the ABB COM600 station gateway, which aggregates IEC 61850 data from multiple RED Series relays and presents a unified data model to the SCADA layer via IEC 60870-5-104 or DNP3 protocol conversion.

At the control level, the ABB AC500 PLC series can receive protection status data and interlocking signals from the 1MRK000195-AAR02 through the station bus, enabling coordinated automation logic between protection functions and process control. HMI panels such as the ABB CP600 series display real-time relay status, fault event records, and alarm conditions sourced directly from the RED Series relay network, giving operators immediate situational awareness on the plant floor.

For remote monitoring and diagnostics, the 1MRK000195-AAR02 supports MMS client-server communication with SCADA platforms including ABB Ability System 800xA and third-party SCADA systems compliant with IEC 61850. Fault disturbance records, event logs, and setting group data can be retrieved remotely without interrupting protection functions, enabling predictive maintenance workflows and reducing unplanned downtime. Integration with edge gateway devices such as the ABB Edge Connect further extends remote diagnostic capability to cloud-based asset management platforms.

In multi-bay substation configurations, the 1MRK000195-AAR02 works alongside ABB REC615 bay control units and ABB REB615 busbar protection relays to form a fully coordinated IEC 61850 protection and control network. Industrial Ethernet switches with RSTP/PRP/HSR redundancy protocols ensure that the communication network remains available even during single-point failures, maintaining continuous data flow between all nodes in the protection architecture.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial power protection environments is the coexistence of legacy hardwired relay systems alongside modern digital communication networks. Older protection schemes rely on discrete copper wiring for trip signals, alarm outputs, and interlocking, creating data silos that prevent centralized monitoring and make fault diagnosis time-consuming and error-prone.

The ABB 1MRK000195-AAR02 directly addresses this challenge by providing a standardized IEC 61850 communication interface within the RED Series platform. By replacing point-to-point copper wiring with GOOSE-based logical connections, the board eliminates data isolation between protection zones, enabling a single unified network to carry trip commands, blocking signals, and status information across the entire substation. This not only reduces installation cost and wiring complexity but also makes the protection scheme fully visible and auditable from the SCADA level.

For production line transparency, the 1MRK000195-AAR02 enables continuous streaming of protection relay status data to MES and ERP systems via the SCADA gateway layer. Plant managers can monitor feeder loading, transformer utilization, and protection event history in real time, enabling data-driven decisions on maintenance scheduling and capacity planning. When a fault occurs, the relay’s disturbance recorder captures pre-fault and post-fault waveforms, which are automatically uploaded to the SCADA historian for root cause analysis — eliminating the need for manual on-site data collection.

System expansion is equally straightforward. The IEC 61850 architecture supported by the 1MRK000195-AAR02 is inherently scalable: new protection relays, bay controllers, or merging units can be added to the station bus without rewiring existing devices. Configuration changes are managed through the ABB PCM600 Protection and Control IED Manager, which provides a centralized engineering environment for relay parameterization, communication configuration, and firmware management across the entire RED Series fleet.
