GE Multilin 750/760 - Legacy Feeder Protection System

he baud rate of all the serial ports is variable from 300 to 19.200 bps. The optional Ethernet port can be used to connect the 750/760 to 10 Mbps Ethernet networks. 

The 750/760 supports ModBus® RTU, DNP3.0 Level 2. and ModBus® RTU TCP/IP protocols.

The three serial ports support ModBus® RTU protocol, while any one of the two rear ports but not both can be configured to support DNP 3.0 Level 2. 

The optional Ethernet port supports ModBus® RTU via TCP/IP protocol. The communication system of the 750/760 is designed to allow simultaneous communication via all ports.

Using Ethernet as the physical media to integrate the 750/760 to Local or Wide Area Networks, replaces a multipoint wired network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing monthly operating costs.

User Interface

Various user interfaces facilitate operation of the 750.

Display

A 40 character display allows access to setpoints, actual values, and diagnostic messages generated by a trip or alarm condition. The 750 can display 30 user-selected messages during keypad inactivity.

Indicators

Twenty LEDs indicate relay status, system status, and trip and alarm conditions.

IRIG-B Input

This feature provides time synchronization via standard GPS clock inputs.

EnerVista Software

The EnerVista™ Suite is an industry-leading set of software programs that simplifies every aspect of using the 750/760 relay. 

The EnerVista™ suite provides all the tools to monitor the status of your protected asset, maintain the relay, and integrate information measured by the 750 into DCS or SCADA monitoring systems. 

Convenient COMTRADE and Sequence of Events viewers are an integral part of the 750 Setup software included with every 750 relay, to carry out postmortem event analysis to ensure proper protection system operation.

Retrofit Existing SR 750 Devices to the Multilin 850 in Minutes

Traditionally, retrofitting an existing relay has been a challenging, time consuming task often requiring re-engineering, new drawings, panel modifications, re-wiring and re-testing.

The 8 Series Retrofit Kit provides a quick, 3-step solution to upgrade previously installed SR 735 or SR 750/760 Devices. 

With the new 8 Series Retrofit Kit users are able to install the 850 Feeder Management System without modifying existing cutouts and wiring, and without any drawing changes or re-engineering time.
