Product Overview
ABB LD MUI-01 is a Local multi-functional human-machine interface unit specifically designed for Relion® 615, 620 and 650 series multi-functional protection relays (such as REF615, REM615, REF650, RED650, etc.) Multi-function User Interface. This device communicates with the main relay via a dedicated connection cable, providing an intuitive LCD display, operation keys and status indicators. This enables maintenance personnel to directly view measurement values, confirm alarms, execute control commands or configure parameters on-site without relying on remote SCADA or engineering laptops.
