The GE Multilin SR489-P5-HI-A20-E generator management relay is designed for the protection, control and advanced communication of small to medium-sized generators. It features comprehensive protection functions such as generator stator differential protection, stator and bearing thermal monitoring, and vibration monitoring. In addition, the SR489-P5-HI-A20-E features a large, user-friendly front-panel interface and enhanced troubleshooting capabilities with IRIG-B time-synchronized event logging, waveform capture and data logger. Communication via industry-standard hardware and protocols makes it a cost-effective choice for generator management.
Functions and features:
Protection function: The relay is capable of monitoring various operating parameters of the generator, such as voltage, current, frequency and power. When these parameters are out of the safe range, the relay will trigger the corresponding protective actions, such as disconnecting the power supply or activating an alarm, to prevent the generator from being damaged.
Control function: In addition to the protection function, the relay can also be used to control generator operations such as starting, stopping and switching. It can control the generator's operating status according to preset logic or external signals to ensure the stable operation of the power system.
Programmability: The GE SR489-P5-HI-A20-E generator management relay has a programmable function, which allows users to set the parameters and logic of the relay according to specific application requirements.
Communication function: The relay supports a variety of communication protocols and interfaces, such as Modbus, Profibus, etc., which is convenient for data exchange and remote monitoring with other devices or systems.
High Reliability: Strict quality control and testing ensure stable operation even in harsh industrial environments.
