GE UR7HH Communications Module

Technical Specifications 

Providing two channels for interrelay communications, the UR-7HH Communications Module is intended for installation in the Universal Relays series. The module provides the relay with two LED channels that are multi-mode and function at a wavelength of 820 nm. While multi-mode fiber optic wiring is considerably cheaper than single-mode, attenuation (or loss of signal/loss of dB) is greater over long distances for multi-mode setups than for single-mode. 

Features

The UR-7HH is a COMMS module for use with the UR Series of Multilin Universal Relay Systems. The inter relay communication characteristics of the UR-7HH include a 820 nm, multimode, LED, with 2 channels.  Each universal relay is featured with high-speed communication capabilities with a communication switch, an IEC Process Bus, and inter-relay communication abilities. The communication abilities make it seamless for a Multilin universal relay to integrate in to existing systems or infrastructures. There are three Ethernet ports available to combat heavy Internet traffic conditions and reduce any potential latency effects. The updated communications features are the IEC 61850 DNP 3.0 with a Modbus TCP/IP and IEC 60870-5-104 protocols. There are IEEE C37.118 synchrophasors as well over the Ethernet connection. 

Relevant UR-7HH Software Details

The Universal Relays series is able to display data generated from module activity and display it to the user passively through the LED located on the unit’s faceplate or more effectively through a computer connected to the relay running Multilin’s EnerVista software program. The EnerVista software program provides a streamlined user interface for monitoring channel health and trending and exporting data related to ongoing interrelay communications. EnerVista UR has extremely light hardware requirements, making implementation of the program convenient and inexpensive.
