SR489-P5-LO-A20-E Agdor wire relay

SR489-P5-LO-A20-E is a General Electric (GE) Agdor wire relay designed for generator protection

and can be used in induction or synchronous generators. The device can operate at 25, 50 or 60 Hertz.
It has a 40-character display that allows users to view numerical information, diagnostics, and set values.

The front panel includes a numeric keypad, status indicators, numerical up and down keys, RS232 port interfaces,

and control and programming keys, including reset, input, menu, menu Up, and menu Down keys. This allows control without being connected to an external computer.

In addition, it has four isolated 4-20 mA analog inputs and outputs and seven assignable digital inputs. There are seven

CT inputs for three-phase output/three-phase neutral line and ground current detection, as well as a separate safety

and filter ground. The backplane includes four isolated RTD inputs, six output relays, two RS485 communication ports,

and four VT inputs. Communication ports can use ModbusRTU or DNP 3.0 protocols up to 19200 bps (or both).
