Overview

The ABB 1MRK000008-NB Bay Control Display is engineered as a Human-Machine Interface (HMI) for substation automation and bay-level control. It provides operators with clear, real-time visualization of key system parameters such as voltage, current, breaker status, and protection functions. The display supports intuitive navigation through physical buttons and a rotary knob, ensuring fast access to critical settings and alarms. Its compact design and robust construction make it suitable for harsh industrial environments, including marine and offshore installations. Additionally, the display is compatible with ABB’s REC670 and other Relion® series relays, enhancing operational safety and situational awareness.

Technical Data / Specifications

Typical Applications 

The 1MRK000008-NB display is widely used in medium-voltage substations for bay-level control and monitoring. It interfaces with ABB protection relays to provide real-time feedback on breaker status, fault conditions, and system health. For example, in a utility substation, operators use this display to monitor feeder performance and respond to alarms.

The module also supports integration with SCADA systems, allowing for remote diagnostics and centralized control. Its ergonomic interface and rugged design make it ideal for both retrofit projects and mission-critical installations.
