The 489-P5-HI-A20-E “is a generator management relay manufactured by GE Multilin.
The specific characteristics of the relay are as follows:
Phase CT secondary coil: has 5A phase CT secondary coil.
Control power supply: High control power supply range is 90-300V DC and 70-265V AC, frequency is 48-62Hz.
Analog output: Analog output is 4 to 20mA.
Display: Features a larger LCD and Ethernet enhanced display.
Conformal coating: Conformal coating in harsh environments protects the unit from chemicals.
Its common technical parameters also include:
Analog current input: the input impedance is 226Ω±10%, the conversion range is 0 to 20mA, the accuracy is 1% of the full scale, it is a passive input, the value of the analog input power supply is + 24Vdc at 100mA, the sampling interval is 50ms, and the analog input frequency tracking value is 6V, 10Hz/second.
Digital input: There are 9 optically isolated inputs, the external switch is a dry contact of less than 400Ω, or the collector NPN transistor is disconnected from the sensor, and the 489 sensor power supply is 24Vdc at 0mA.
Ground current input: CT primary is 10 to 10000A, CT secondary is 1A/5A, for 1A/5A CT, conversion range is 0.02 to 20×CT.
