GE Multilin 269PLUS-DO-100P-120 Motor Management Relay

Description

The GE Multilin 269PLUS-DO-100P-120 is a digital motor management relay engineered for adaptability across a diverse range of AC motor protection applications. This device features automated operational adaptation, enabling it to continually learn and update critical motor parameters such as acceleration time and cool-down rates to optimize protection configuration for individual medium-sized motors. These learned parameters, alongside relay setpoints, motor statistical data, and pre-trip values, are securely retained within non-volatile memory to guarantee data integrity during control power interruptions. As a drawout version, the 269PLUS-DO-100P-120 permits direct removal from service for maintenance or testing without requiring the host motor to be shut down. When integrated with a compatible GE Multilin meter, the relay expands its diagnostic capabilities to incorporate non-volatile memory protection functions driven by Power Factor, voltage, kVars, and voltage-sensed phase reversals.

Features

• Automated parameter tracking continuously learns acceleration time and cool-down rates for optimized individual motor protection.
• Non-volatile memory storage preserves learned motor statistics, relay setpoints, and pre-trip configurations during loss of control power.
• Drawout construction enables hardware removal from service without interrupting active motor operations.
• Dedicated contact arrangement comprising one set of alarm contacts, one set of Auxiliary 1 contacts, and one set of Auxiliary 2 contacts.
• Dual monitoring capabilities for multiple motor starts to assist in structural thermal stress detection and operational analysis.
• Integrated emergency restart potential accompanied by user-configured pre-trip warnings and preventative alarms.
• Stator winding and bearing overtemperature thermal tracking through programmable overload curves and specialized FlexCurve layouts.
• Support for expanded voltage and power metering functionality when paired with an external GE Multilin meter.

Applications

• Comprehensive protection and management for medium-sized AC motors.
• Temperature-critical installations requiring explicit stator winding and bearing monitoring.
• Continuous-duty manufacturing environments where drawout maintenance capabilities prevent operational downtime.
• Voltage and power factor-sensitive power distribution networks utilizing cooperative external metering systems.

Technical Specifications

Installation Guidelines

• Moisture and Dust Protection: To achieve the designated NEMA 12 / IP53 rating, ensure the enclosure interface is fully sealed in accordance with the specified guidelines during panel integration.
• Drawout Operation: Refer to the instruction manual reference 1601-0013-D3 for specific mechanical interlock procedures during insertion or removal of the drawout chassis while the motor remains operational.
• Analog Signal Routing: Because the analog current output is non-isolated and functions as an active source, proper shielding and isolation procedures must be applied to external receiving equipment to avoid ground potential variance
