GE Multilin 269-100P-HI (269PLUS Series) Microcomputer-based Motor Management Relay

Product Description

GE Multilin 269-100P-HI (269PLUS series) microprocessor-based motor management relay, a comprehensive protection and monitoring device for industrial three-phase AC motors. This model is equipped with 100Ω platinum RTD temperature measurement inputs, complete motor thermal model, multi-dimensional fault protection, event recording and trend capture functions. It comes with backlit alphanumeric display, keypad configuration and status LED indicators. Standard RS485 Modbus RTU communication allows connection to PLC/DCS host systems for remote monitoring. The housing is flame-retardant and corrosion-resistant with front panel IP40 rating. It supports on-site setting, fault capture, pre-alarm and emergency restart logic, commonly installed in motor control centers (MCC). This is a discontinued legacy product; GE 859 motor relay is recommended as replacement.
