Product Description

Overview

The ABB 1MRK000614-ABR02 is a high-density Binary Output Module (BOM) engineered for the Relion 670 and 650 series of Intelligent Electronic Devices (IEDs). It provides 24 relay outputs, enabling precise switching and control of multiple external devices, such as motors, solenoids, and valves.

Designed for demanding industrial environments, this module combines compact dimensions with robust construction, allowing integration into standard control panels while ensuring long-term reliability in substations and manufacturing plants.

Technical Description

The 1MRK000614-ABR02 serves as a digital interface between the IED and external high-voltage DC circuits, translating control commands from the internal microprocessor to actionable relay outputs.

The "AB" designation identifies the nominal input voltage range of the module, while "r02" indicates the second hardware revision, featuring improved surge protection and extended operational lifespan.

Key Performance Features

Output Capacity

• Provides 24 independent relay outputs for control and automation tasks.

• Each relay is capable of switching standard industrial load currents with high reliability.

Electrical Isolation & Safety

• All outputs are galvanically isolated to protect the IED from high-voltage transients.

• Supports safe operation with both 110 Vdc and 220 Vdc station systems.

Signal Quality & Timing

• Integrated digital filtering reduces relay chatter and false triggering.

• High-speed switching with 1 ms timestamp accuracy for Sequence-of-Events (SOE) recording.

Robust Industrial Design

• Complies with IEC 60255-22-1 for surge immunity and IEC 61000-4 EMC standards.

• Operates reliably in extreme temperatures from -40°C to +70°C.

• Continuous self-monitoring reports any internal faults via the IED’s IRF signal.

Technical Specifications

Applications

• Control of motors, solenoids, and valves in power plants and industrial facilities.

• Integration into automation and process control schemes.

• Substation switchyard auxiliary control for circuit breakers, disconnectors, and trip signals.
