The SR489-P5-HI-A20 is a generator management relay manufactured by Multilin for the 489 series.
This relay has the following features and functions:
Control power: HI control power is 90-300 VDC and 70-265 VAC (48-62 Hz).
Analog output: The analog output on the relay is 4 to 20 mA.
Protection function: The relay can monitor the operating parameters of the generator such as voltage, current, frequency and power, and trigger protective actions when these parameters exceed the safe range, such as disconnecting the power supply or activating the alarm to prevent damage to the generator.
Control function: In addition to the protection function, the relay can also be used to control the generator start, stop and switch operations.
Programmable: Relays usually have programmable functions, and users can set the parameters and logic of relays according to specific application requirements.
Communication function: Support a variety of communication protocols and interfaces, such as Modbus, Profibus, etc., to facilitate data exchange and remote monitoring with other devices or systems.
The relay is highly reliable and has undergone rigorous quality control and testing to ensure stable operation even in harsh industrial environments. However, please note that the specific configuration and use should be selected and adjusted according to the generator model, specifications and system requirements. During installation and use, the relevant operation and maintenance specifications should be followed to ensure the safety and reliability of the relay.
