GE Multilin 369 Motor Protection and PLC/DCS Integration Features

The GE Multilin 369 relay incorporates industrial control characteristics associated with GE Multilin motor management systems, including I/O density scaling for configurable protection channels and firmware flash compatibility for device maintenance operations. The relay processes phase current inputs, ground current signals, digital status inputs, and analog outputs for integration with motor control circuits.

The unit supports protection functions including ANSI 49 thermal overload, ANSI 50/51 phase overcurrent, ANSI 50G/51G ground fault protection, ANSI 46 current unbalance protection, ANSI 37 undercurrent protection, ANSI 86 lockout operation, ANSI 48/66 start supervision, and ANSI 51R mechanical jam/stall detection.

Frequently Asked Questions

Q: What current transformer inputs are supported by the GE Multilin 369 relay?
A: The relay accepts 1 A or 5 A secondary CT inputs for phase current measurement and configurable ground current inputs.

Q: What communication interfaces are available on the 369-HI-0-0-0-0-H-E model?
A: The relay provides a rear RS485 port supporting Modbus RTU communication and a front RS232 port for local configuration.

Q: Does the relay support thermal monitoring during motor operation?
A: Yes. The relay executes a motor thermal model that tracks thermal capacity usage, trip conditions, and estimated restart availability.

Field Installation Guidelines

Install the relay in a suitable panel cut-out location using the specified drawout mounting arrangement. Verify control power polarity and voltage range before energizing the unit.

Route CT wiring separately from high-voltage switching conductors to reduce induced electrical noise. Use shielded communication wiring for RS485 networks where required, with cable shields terminated according to site grounding practices.

Confirm CT secondary connections, digital input polarity, and output relay wiring before commissioning. For installations using the E conformal coating option, maintain enclosure protection to prevent exposure to excessive contaminants or conductive moisture.
