GE 269PLUS-D/O-111-100P-HI Motor Management Protection Relay

Product Description

GE Multilin 269PLUS‑D/O‑111‑100P‑HI is a draw‑out motor management & protection relay within legacy discontinued 269PLUS series, dedicated for three‑phase industrial AC motor protectionGE Vernova. D/O denotes draw‑out plug‑in housing; 111 defines I/O arrangement; 100P stands for 100‑ohm platinum RTD support; HI indicates wide‑range high‑intensity auxiliary power supply. This unit integrates motor thermal‑model protection, electrical fault protection, winding & bearing RTD temperature monitoring, event logging and built‑in diagnostics. Equipped with LCD display and keypad, isolated RS485 Modbus‑RTU communication for SCADA / DCS interfacing. Configuration and post‑fault analysis are performed via EnerVista 269 software. Deployed within Motor Control Centers (MCC) as full‑function protection, monitoring and trip‑control unit for LV & MV motors, widely used for spare‑part replacement and legacy‑relay retrofit projects.
