GE 369-HI-R-M-0-0 Motor Protection Relay

Configured for comprehensive motor safety and diagnostic processing within industrial power control networks, the GE Multilin 369-HI-R-M-0-0 (369 Motor Protection Relay) provides direct physical/electrical execution. This microprocessor-based hardware platform samples real-time physical variables to prevent motor insulation breakdowns, phase faults, and thermal overload tracking issues across industrial motor installations.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Architecture

The internal computational architecture uses high-density processing units to maintain optimal communication velocity across the module backplane bus. Maintaining specific firmware flash compatibility benchmarks across all active registers allows the system logic to scan the 12 RTD inputs, line metrics, and fault registers simultaneously. Raw analog signals are processed through shielded input channels and converted into digital data streams for the central processor. The internal bus delivers real-time calculation of thermal capacity, phase balance, and optional metering metrics, routing trip commands and diagnostic states directly to the enhanced front-panel interface or rear serial communication links within millisecond intervals.

Frequently Asked Questions

Q: How does the "M" configuration choice alter the basic operational features of the 369-HI-R-M-0-0 relay?

A: The "M" variable indicates the inclusion of the optional metering package. This hardware layer enables the processor to compute and log active parameters like line voltage, system frequency, real power (kW), reactive power (kVar), apparent power (kVA), and power factor alongside standard current and temperature profiles.

Q: What are the specific threshold boundaries for the high-range (HI) control power input loop?

A: The high-range power configuration supports operational inputs from 50 to 300 V DC or 60 to 265 V AC at line frequencies of 50/60 Hz. The internal power converter conditions these inputs to supply stable low-voltage DC rails to the logic board and input sensing arrays.
