GE 369-HI-R-M-0-0-0-E Motor Management Relay

• RTD Inputs: Equipped with multiple Resistance Temperature Detector (RTD) channels for direct monitoring of motor winding and bearing temperatures.
• Communication Interfaces: Features Modbus RTU over RS-485 as standard; optional communication modules support Ethernet, DeviceNet, or Profibus for integration into SCADA and DCS systems.
• Display and Interface: Includes a backlit LCD display with local keypad for on-site configuration, status viewing, and event review.
• Event Recording: Offers sequence of events (SOE) recording with time stamps for fault analysis and system diagnostics.
• Power Supply: Operates on a wide-range auxiliary power supply, typically 85–265 VAC/VDC, enabling flexibility in installation across different power sources.
• Environmental Specifications: Designed for industrial environments with an operating temperature range of -20°C to +60°C, high immunity to electromagnetic interference (EMI), and robust insulation and isolation.
• Mounting: Panel-mounted or DIN rail installation with standard cutout dimensions for integration into motor control centers (MCCs) and switchgear panels.

Function Features:

• Comprehensive Motor Protection: Delivers advanced protection algorithms to prevent motor damage from electrical, thermal, and mechanical faults.
• Programmable Logic: Allows users to configure custom logic using built-in programmable function blocks, enabling tailored control strategies without external relays.
• Thermal Modeling: Simulates motor heating and cooling curves to prevent restarts when the motor is still thermally stressed, reducing mechanical stress and extending motor life.
• Trip and Alarm Outputs: Provides multiple relay outputs for trip signals, alarms, and status indication, configurable based on application needs.
• User-Friendly Configuration: Setup and monitoring are facilitated through the front keypad, local display, or via software tools such as GE Enervista 369 Setup.
• Cyber Security: Supports password protection and access control to prevent unauthorized changes to settings.

Applications:

• Industrial Motor Control: Widely used in manufacturing, mining, and processing plants for protecting critical motors driving pumps, compressors, fans, and conveyors.
• Power Generation Facilities: Implements protection for auxiliary motors in boiler feedwater systems, cooling water pumps, and forced draft fans.
• Oil and Gas Industry: Applied in offshore platforms, refineries, and pipeline pumping stations for reliable motor protection in hazardous and remote environments.
• Water and Wastewater Systems: Protects large submersible and centrifugal pumps in pumping stations and treatment plants.
• HVAC Systems: Used in large commercial and industrial buildings for chiller and cooling tower motor protection.
• Mining and Heavy Industry: Supports continuous operation of crushers, mills, and ventilation systems where motor reliability is critical.
