Low Voltage 4-20 mA Analog Output Relay model 489-P5-LO-A20-E can be used alongside a generator and is typically used to both manage and protect the generator. The associated phase current inputs associated with this model are five ampere CT secondaries.
The 489-P5-LO-A20-E is a GE Multilin Relay from GE’s SR family of relays (in the same family as the GE Multilin 469 Motor Protection Relay and the GE Multilin 735 Feeder Protection Relay.) The 489-P5-LO-A20-E is designed for Generator Protection and can be used for induction or synchronous generators. The unit can be operated at 25, 50 or 60 Hz.
The 489-P5-LO-A20-E is designed with a 40-character display that allows users to view value messages, diagnostics, and setpoints. The front panel includes a numeric keypad, status indicators, value up and down keys, an RS232 port interface, and control and programming keys including reset, enter, menu, menu up, and menu down keys. This allows control without connecting to an external computer. |
