PRODUCT INFORMATION
Product Overview
The General Electric 269PLUS-DO-211-100P-120VAC is a Multilin Motor Management Relay. This system provides protection to three-phase motor systems functioning near operational limits. External current transformers monitor the electrical characteristics of the connected motor. Ten dedicated inputs support 100 Ohm platinum resistance thermal detectors for temperature monitoring. An unbalance input feeds electrical data directly to thermal memory.
The unit includes an RS485 communications port for external network interfacing. Four primary output relays manage external device control and communication. These outputs configure for either latched or non-latched operational modes. Integrated analog outputs report motor current, CT secondary current, and stator or bearing RTD temperatures. A front 48-character alphanumeric LCD screen displays real-time current values, alarms, and programming. Five LED indicators display individual relay output states and self-test alarm conditions.
