Product Introduction
GE Multilin 369-HI-R-M-F-D-H-E is a fully equipped motor management relay for critical three-phase AC motors. It provides thermal overload, phase loss, unbalance, ground-fault, jam/stall, and RTD-based temperature protection with true-RMS metering and multi-protocol communications.
This configuration adds 12 RTD inputs, a metering package, a fiber-optic port, DeviceNet interface, harsh-environment build, and enhanced diagnostics. Control power accepts 50-300 VDC or 60-265 VAC, making it suitable for both DC UPS systems and AC auxiliary supplies.

Quality Control Process (DYNAMIC GENERATION)
- Front-panel and display check. We verify the LCD, keypad, status LEDs, and motor/output indicators for full functionality.
- Control power-up test. The relay is energized at both AC and DC rated levels to confirm stable boot, self-test pass, and no nuisance trips.
- RTD and metering validation. Each RTD channel is tested with known resistance values, and CT/VT inputs are checked for accurate current, voltage, power, and frequency readings.
- Communication port verification. RS485 Modbus RTU, fiber-optic link, and DeviceNet interface are all tested for proper connectivity and protocol response.
- Relay output and final packaging. Each output relay is pulsed under load, then the unit is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm the full option code before ordering. The 369-HI-R-M-F-D-H-E includes RTD, metering, fiber optic, DeviceNet, harsh environment, and enhanced diagnostics. A base 369 or partial option unit will not support the same wiring or setpoints.
❗ Fiber-optic and DeviceNet settings must be reconfirmed. New relays ship with default communication parameters. If the old unit had custom DeviceNet node addresses, baud rates, or fiber link settings, the replacement will not communicate until reconfigured.
❗ RTD wiring requires shielded cable. Unshielded RTD runs in MCC environments pick up noise and can cause false temperature trips. Ground the shield at the relay end only.
❗ Harsh environment rating is not universal. The H option provides enhanced environmental protection, but it does not change the panel IP rating. Ensure the enclosure meets the required environmental standards.
Keep these in mind and you’ll cut 90% of rework time.
