The Agdo relay is part of the GE SR family of relays, and the SR489-P5-LO-A20-E is designed for generator protection and can be used in induction or synchronous generators. Model number 489-P5-LO-A20-E, the device is designed with a 40-character display that allows users to view numerical information, diagnostics, and set values. The front panel includes a numeric keypad, status indicator, 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.

The Agro Multi-wire relay is a General Electric SR series multi-wire relay, SR489-P5-LO-A20-E for generator protection. The relay can operate at 25, 50 or 60 Hertz and has a 40-character display that allows users to view numerical information, diagnostics and set values. In addition, it has a backplane that includes 12 RTD inputs, 6 output relays, 2 RS485 communication ports, and 4 VT inputs. RTD is field programmable and the communication port can use ModbusRTU or DNP 3.0 protocols (or both) up to 19200 bps. 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. All inputs of Agdor wire relay meet SWC, C37.990 EMI, RFI anti-interference.
