Specifications

Description

The 369-HI-R-M-0-0-H-E is an advanced industrial-grade motor management relay that integrates protection, monitoring, and signal transmission. As a core component for power asset protection, this relay employs a sophisticated thermal model algorithm to dynamically simulate the motor's operating state, effectively preventing electrical faults such as overload, stall, and phase anomalies. Its enhanced design gives it excellent grid adaptability, maintaining the continuity of control logic even in complex power fluctuation environments.

Applications

Heavy-duty paper mills: Monitor large pulper motors, transmitting real-time current data to the central control room's DCS system via a 4-20 mA interface for precise process control.

Large fertilizer plants: Deployed in the synthetic ammonia compressor control unit, utilizing waveform capture to perform in-depth root cause analysis of trips caused by power grid fluctuations.

Mining and beneficiation plants: Utilizing an extremely wide operating range of -40°C, ensuring the all-weather operational safety of crusher and ball mill drive systems in high-altitude, cold regions.

Municipal water supply plants: Responsible for the protection and management of high-power deep well pumps, adapting to pointer-type instruments in older machine rooms and modern PLC systems through multi-range analog outputs.

Cement processing plants: Used for monitoring the thermal capacity of rotary kiln main motors, rapidly isolating power in the event of mechanical jamming through high-speed differential switch protection.

Inputs and Outputs

Offers a variety of inputs and outputs for comprehensive motor management.

Speed Switch Input: Allows external speed devices to distinguish between a normal start and a locked rotor condition, enabling relay shutdown when conditions are poor.

Other inputs include Waveform Capture and Digital Counters.

Enhanced Features and Durability

This specific model includes an enhanced diagnostic and faceplate option, offering a cleaner design.

Features a conformal coating, a thin polymeric film that protects the relay from:

Variable temperatures

Corrosive materials

Dust

Humidity

Installation

Mounted in a DEMO metal carry case, providing protection against environmental factors.

The case is flame and corrosion retardant.

Should be mounted away from strong magnetic fields or high current conductors to prevent long-term damage to the relay.

FAQ

Q: Can you explain the optional metering package included in the 369-HI-R-M-0-0-H-E Multilin GE motor management relay for three-phase motor monitoring?
A: The optional “M” package adds high-accuracy power metering, including kW, kVA, kVAR, energy (kWh/MWh/kVARh/MVARh), power factor, and frequency. It also supports event logging with up to 512 records triggered by power loss, alarms, self-test, waveform capture, and trip events.

Q: What are the analog outputs for option M in the 369-HI-R-M-0-0-H-E relay?
A: It provides programmable outputs of 0–1 mA, 0–20 mA, or 4–20 mA. Maximum load is 2400 Ω for 0–1 mA and 600 Ω for the other two ranges.

Q: What does the 2400 Ohm maximum load capacity mean for the 369-HI-R-M-0-0-H-E model?
A: It allows stable current output over long cable runs or multiple connected instruments without needing a signal amplifier.

Q: How does the 369-HI-R-M-0-0-H-E perform in a DC power supply environment?
A: It supports up to 250 VDC input, handling voltage fluctuations in substation DC bus systems.
