Chapter 2: Product description
Product description
This chapter outlines the product, order codes, and specifications.
Product description
The Multilin DGPR is a retrofit solution for the Digital Generator Protection (DGP) Relay. The
DGPR is a one-to-one replacement of a DGP relay and includes a G60 Generator Protection
System, which is part of the GE Universal Relay (UR) series of products.
The G60 is a microprocessor-based relay that measures generator conditions directly via
CT and VT inputs and via other sources of information, such as analog, communication,
and contact inputs. The G60 protects, controls, and monitors the operation of generators
driven by steam, gas, or hydraulic turbine.
One of the benefits of the DGPR is ease of wiring. Simply disconnect the wires from the
back of the DGP and connect them to the back of the DGPR.

The DGPR solution includes
• G60 relay with redundant power supply
• Five test switches for CT, VT, Trip, and DC circuit isolation on the front of the unit
• Eight 14-pin terminal blocks at the back of the unit to replicate DGP terminals
The DGPR is pre-wired for all connections between the G60, test switches, and terminal
blocks.

CHAPTER 2: PRODUCT DESCRIPTION ORDER CODES
MULTILIN DGPR – INSTRUCTION MANUAL 5
Order codes
This section lists the order codes for the Multilin DGPR.
The G60 order code provided in the package is
G60-UA4-HKH-F8M-H6P-M8M-P6M-U6C-WRH
For more information, see the Order Codes section in the G60 instruction manual.
Order codes are subject to change without notice. See the ordering page at
https://store.gegridsolutions.com/ for the latest options.
Table 1 outlines order codes. As an example, with
DGPR-S-D1-RE0-BF0-GS1-DS0-RES0-BFS0-DWG0-GPM0-64S0, the D1 option means that a
Line Protection System (LPS-O) cover plate is included, while the GS1 options means that
DGP settings are to be converted to the G60 settings. That is, GE converts DGP settings and
uploads them to the G60. The LPS-O cover plate is mounted in the replacement of the LPS-
O unit when it is removed from the panel.
