GE 269PLUS-D/O-211-100P-HI Motor Management Relay

Technical Specifications

The 269PLUS-D/O-211-100P-HI provides 4 programmable output relays supporting latched or non-latched configuration for tripping and external communication. It includes 1 programmable analog output port to transmit current and RTD temperature signals. The front panel contains 12 operation keys, a 2-line 48-character alphanumeric LCD, and 5 status LED indicators. The device also incorporates a 2-wire RS-485 serial communication port supporting the Modbus RTU protocol for transferring configuration files and viewing motor statistical records.

Protection and Monitoring

The 269PLUS-D/O-211-100P-HI utilizes microprocessor logic for motor protection. It tracks temperature data through 10 100-ohm platinum RTD inputs, combining these readings with phase unbalance and negative-sequence current measurements from the CTs for thermal memory and cooling calculations to prevent component overheating. Trip and alarm functions consist of custom and 8 standard overload curves, phase loss, phase unbalance, ground fault, short circuit, locked rotor, mechanical jam, and undercurrent. Auxiliary interfaces accommodate a speed switch, external differential relay, and spare inputs.

Primary Applications

The product protects and manages motor assets across industries including fan and pump control systems in power plants large compressors and transmission pump groups in oil gas and chemical sectors and machinery such as crushers band saws and chippers in mining papermaking and metallurgical fields.
