    • SR489-P5-HI-A20 Relay Technical Parameters Introduction in Chinese

      SR489-P5-HI-A20 is a generator management relay manufactured by GE Multilin for the 489 series, specifically designed for generator protection and control in power systems. The following is a detailed Chinese introduction to its technical parameters:

      Control power supply voltage:
      DC range: 90 to 300 volts direct current (VDC).
      Communication range: 70 to 265 volts alternating current (VAC), with a frequency range of 48 to 62 hertz (Hz).
      This relay can operate stably over a wide range of voltages and frequencies, adapting to the needs of different power systems.
      Current input:
      CT secondary coil: 5 amperes (A).
      The relay is equipped with a 5A phase CT secondary coil to monitor the current situation of the generator and ensure that the current is within a safe range.
      Analog output:
      Output range: 4 to 20 milliamps (mA).
      Relays provide analog outputs ranging from 4 to 20mA, facilitating data exchange and remote monitoring with other devices or systems.
      display:
      Basic display: SR489-P5-HI-A20 is equipped with a basic display for displaying key operating parameters and status information.
      There is also an enhanced display version (such as SR489-P5-HI-A20-E) with a larger LCD screen and richer display information.
      Protection function:
      Relays can monitor various operating parameters of generators, such as voltage, current, frequency, and power.
      When these parameters exceed the safe range, the relay will trigger corresponding protective actions, such as disconnecting the power supply or starting an alarm, to prevent damage to the generator.
      Control function:
      Relays can be used to control the starting, stopping, and switching operations of generators.
      According to preset logic or external signals, relays can accurately control the operating status of generators, ensuring the stable operation of the power system.
      Programmability:
      Relays usually have programmable functions, and users can set the parameters and logic of the relay according to specific application requirements.
      This enables the relay to adapt to different generator systems and operating environments, improving flexibility and adaptability.
      Communication function:
      Relays typically support multiple communication protocols and interfaces, such as Modbus, Profibus, etc.
      This enables relays to easily exchange data and remotely monitor with other devices or systems, achieving intelligent management of the power system.
      Environmental adaptability:
      Protection level: This model of relay does not particularly emphasize conformal coating protection in harsh environments (such as chemical environment conformal coating H option not specifically mentioned in this model), but relay design usually considers certain industrial environment adaptability.
      Working temperature range: The relay can operate stably within a wide temperature range, adapting to the generator protection requirements under different environmental conditions.
      Other features:
      High reliability: Relays undergo strict quality control and testing to ensure stable operation even in harsh industrial environments.
      Installation method: Supports vertical or horizontal installation, making it easy to flexibly arrange according to the actual situation on site.
