Product description

The 489-P5-HI-A20-T-H is a generator management relay manufactured by GE Multilin for the 489 series. This relay has 5 A phase CT secondary. HI control power supply is 90-300 VDC, 70265 VAC, 48-62 Hz. The analog output on this relay is 4 to 20 mA. The relay features a larger LCD and an enhanced display of Ethernet. Conformal coatings for harsh environments protect the unit from chemicals.

Relay analog current input: input impedance 226 Ω±10%. The value ranges from 0 to 20ma. The accuracy is ±1% of full scale. These are passive inputs. The maximum analog input power is +24 VDC at 100 mA. The sampling interval is 50 milliseconds. The minimum analog input frequency tracking is 6v, 10hz/SEC. Digital inputs on the relay: There are 9 optical isolated inputs. External switch dry contact less than 400 Ω, or open collector NPN transistor from sensor. The 489 sensor power supply is 24 volts DC with a maximum of 20 mA. Relay grounding current input :CT primary input 10a ~ 10000a, CT secondary input 1a / 5a. The conversion range is 1A/5A CT from 0.02 to 20 × CT. For neutral voltage inputs, the VT ratio is 1.00 to 240.0:1, and the step is 0.01. Secondary VT is 100 volts at full scale. The conversion range is 0.005 to 1.00(multiplied by full scale). The maximum continuous neutral voltage input is 280 VAC.
