Product description

The 489-P1-LO-A20-E is a 489 generator management relay from Multilin. The unit has a 1A phase CT input with a control voltage of 20 to 60VDC or 20 to 48 VAC @ 48-62 Hz. The unit has a large LCD enhanced display and 4-20 mA analog input.

As part of the GE SR family of relays, the 489-P1-LO-A20-E provides cost-effective protection and control and encapsulates advanced communications. The unit is designed to pair small to medium sized generators to provide protection and reduce troubleshooting time. The unit is easy to use and provides analog inputs for vibration monitoring, as well as rtd for bearing thermal protection.

The 489-P1-LO-A20-E has a large, easy-to-read front panel with a 40-character display along its top edge. The display allows the user to view set and actual value messages as well as diagnostic and default messages. The front panel is equipped with a numeric keypad, numeric up and down keys, program port interfaces, multiple status indicators, and control and programming keys. The bottom edge of the front panel includes a pull-out handle that can be fitted with a lead seal to prevent unauthorized removal.

The device supports direct integration into most DCS and SCADA systems. Supports DNP 3.0, Modbus RTU, and Modbus TCP/IP protocols. The grounding of this unit meets the anti-interference of C37.90 EMI, SWC, RFI.
