GE Power Management SR489 Generator Management Relay

Fault data: Retain the last trip data and pre trip data, support waveform capture (16 cycles), and assist in root cause analysis of faults.

2. Self diagnosis and testing

Self testing: Built in self diagnostic function, triggering alarm contacts when abnormal;

Simulation mode: It can be started without external testing equipment, supports pre fault/fault setting, output relay testing, and simulated input testing, simplifying on-site debugging and training.

Physical and Environmental Characteristics

Structural design: with dust-proof door and drawout case for easy installation and maintenance;

Working environment: The temperature and humidity range is not clearly marked, but as an industrial grade relay, it is usually suitable for -20~70 ℃ (operation) and -40~85 ℃ (storage), with humidity ≤ 95% and no condensation (industry standard, subject to official final specifications);

Certification and compatibility: Specific certifications (such as UL, IEC) are not directly mentioned, but they are suitable for general scenarios of small and medium-sized generators and can be compatible with mainstream control systems through Modbus RTU communication.
