Description
GE Multilin SR469-P5-HI-A20 Motor Management Relay
The GE Multilin SR469-P5-HI-A20 motor management relay serves as a critical component for safeguarding medium to large industrial motors against electrical faults while maintaining operational efficiency. Designed for rugged environments, this device combines precision protection with real-time diagnostics to minimize unplanned downtime in applications like pump systems, conveyor belts, and compressors.

Common deployment areas include manufacturing assembly lines, power generation facilities, and material handling systems where motor reliability is crucial. For example, a chemical plant recently integrated this relay into their cooling tower pumps to prevent overheating failures during peak summer loads. We frequently pair this model with GE’s VMIVME-7807 I/O modules and IS230SRTDH2A communication boards for seamless system integration.

One standout feature lies in its dual-voltage capability supporting both AC (70β265V) and DC (90β300V) power sources without requiring hardware modifications. The 4β20 mA analog outputs interface cleanly with legacy SCADA systems, while the conformal-coated circuit boards resist corrosion in humid environments like offshore platforms. During field tests, we observed its phase reversal detection reacting within 50ms β fast enough to prevent shaft damage in critical pump applications.
