1MRK000614-ABr02 ABB Control Board for Industrial Automation

Description

The 1MRK000614-ABr02 is a control logic unit control board designed for industrial automation, engineered to integrate with ABB relay protection and automation systems including REL, RET, and REF series such as REL670, REF615, and RET670. As a core component of these systems, it executes critical functions: implementing preset logical judgments, action commands, and trip/blocking strategies; performing real-time sampling and analysis of analog and digital inputs including current, voltage, and frequency; collaborating with power boards, communication boards, and human-machine interface panels to enable complete, coordinated control workflows; and monitoring equipment operating status to output alarm, event, and action record data to system platforms or SCADA systems.

Key physical and electrical specifications include: dimensions of approximately 1.365 cm × 9.54 cm, weight of around 0.845 kg, beige finish, and IP20 protection rating (protects against solid objects ≥12.5 mm in diameter, suitable for indoor control cabinet installation). It supports 220V AC input, operates with universal 50Hz/60Hz frequency compatibility, and has a working temperature range of -20 degrees Celsius to +70 degrees Celsius, making it adaptable to diverse industrial environments.
