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

Product Brief Description

The GE Multilin 269PLUS-D/O-111-100P-HI is a drawout (D/O) version of the 269PLUS microprocessor-based motor management relay. Designed for three-phase AC motors, this unit provides full motor protection, real-time monitoring, control and diagnostic functions. It accepts 100Ω platinum RTD inputs for stator and bearing temperature measurement, and the HI suffix indicates a high-range universal power supply (70–265VAC / 88–300VDC). Its drawout housing allows convenient module removal without disturbing field wiring, widely deployed for pumps, fans, conveyors and compressors in water, chemical, mining and power industries.

Product Functions

• Comprehensive motor protection: thermal overload, locked rotor, phase loss, phase imbalance, overcurrent, ground fault and undervoltage protection
• 100Ω platinum RTD temperature monitoring for stator winding and bearing overtemperature alarm and trip
• Accurate current and voltage metering, motor start recording, runtime tracking and load trending for asset management
• Event logging and fault reporting to capture trip records for post-fault root cause analysis
• Programmable digital inputs and relay outputs for motor breaker control, alarm signaling and safety interlock logic
• RS485 Modbus communication interface; configured via GE EnerVista 269 software for parameter setup and diagnostics

Application Scenarios

• Critical pump, fan and conveyor motor protection in water treatment plants and power plant auxiliary systems
• Oil & gas, chemical and mining process motor control and condition monitoring systems
• Industrial manufacturing large low-voltage and medium voltage motor safety supervision
• Facilities requiring drawout relay design for fast spare replacement and maintenance
• Retrofit upgrade projects for older GE 269 series motor protection relays
