489-P5-HI-A1-E GE 489 Series for the GE Generator Management Relays

For the analog current inputs on the relay: The input impedance is 226 Ω ±10%. The conversion range is 0 to 20 mA. The accuracy is ±1% of full scale. These are passive inputs. The analog input supply is a maximum of +24 VDC at 100 mA. The sampling interval is 50 ms. The analog inputs frequency tracking is 6 V minimum and 10 Hz/second. For the digital inputs on the relay: There are 9 opto-isolated inputs. The external switch is dry contact less than 400 Ω, or open collector NPN transistor from sensor. The 489 sensor supply is 24 VDC at 20 mA maximum. For the ground current input on the relay: The CT primary is 10 to 10000 A, and the CT secondary is 1 A / 5 A. The conversion range is 0.02 to 20 × CT for 1A/5A CTs. For the neutral voltage input, the VT ratio is 1.00 to 240.00:1 in steps of 0.01. The VT secondary is 100 VAC at full scale. The conversion range is 0.005 to 1.00 (multiplied by the full scale). The maximum continuous neutral voltage input is 280 VAC.
