Description
Product Overview
369-HI-R-0-0-0-0-E is a Multilin Digital Motor Management Relay manufactured by GE General Electric. It is dedicated to monitoring, protection and control of three-phase AC motors.
The device samples motor voltage, current and winding temperature signals, executes comprehensive motor protection algorithms, sequence control logic and electrical metering. It supports data communication with plant DCS and SCADA systems, and records fault waveforms, startup logs and historical events.
The suffix HI stands for wide-range high control power; R represents relay output configuration; E means enhanced version with advanced diagnostic and data logging functions.
