Description
The GE Multilin UR7HH Communications Module is part of the Universal Relay (UR) series, which provides advanced protection, control, and monitoring for electrical power systems.

The UR7HH module specifically enhances the communication capabilities of the UR relay by allowing it to interface with different communication networks, thereby expanding the relay's integration and data-sharing capabilities within a power management system.

The GE Multilin UR7HH (UR-7HH, part number 3BSE050192R1) is a dedicated inter-relay communications module designed exclusively for integration with GE Multilin’s Universal Relay (UR) Series, serving as a critical connectivity backbone for protective relaying systems in power generation, transmission, and distribution networks, as well as industrial substation automation applications.

Unlike standalone PLC or DCS controllers, this module acts as a high-speed, reliable communication interface that enables seamless data exchange between UR relays, field devices, and upper-layer control/monitoring systems, including SCADA, DCS, or PLC-based automation architectures, without hosting autonomous control logic itself.
