Features:
- UR Universal Relay Series High-performance CPU module
- Designed for installation in the Universal Relays series
- UR devices support power modules for both high voltage (HI) and low voltage (LO) ranges
Universal Relays (UR) is a leading line of protection and control products built on a common modular platform. All UR products offer high-performance protection, scalable I/O options, integrated monitoring and metering, high-speed communication, and robust programming and configuration capabilities. UR lays the foundation for simplified power management and critical asset protection, and can be used as standalone devices or integrated into overall power automation systems.
UR is managed and programmed via EnerVista Launchpad. Each relay comes with this powerful software package, which not only programs the relay's setpoints but also provides setpoint file management, automatic access to the latest firmware/documentation, and an overview of the substation automation system.
The UR9UH GENERAL ELECTRIC CPU module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The UR is available in various configurations and can be equipped with either a 19-inch rack-mount horizontal unit or a smaller (¾) vertical unit. The UR consists of the following modules: power supply, CPU, CT/VT inputs, digital inputs/outputs, sensor inputs/outputs, inter-relay communication, communication switches, and IEC process bus.
The UR9UH, as a central processing unit, is widely used in several core areas of modern power grids:
Asset Protection Solutions: Provides powerful computing capabilities for dedicated protection of generators, transformers, large motors, and transmission lines.
Substation Automation: Serves as a communication hub, integrating field data into SCADA systems using IEC 61850, DNP3, and Modbus protocols.
Digital Fault and Event Logging: Captures high-speed data with 1-millisecond resolution during system disturbances for post-event analysis.
Predictive Maintenance: Analyzes current and voltage trends to identify early signs of equipment failure, such as motor rotor problems or transformer degradation.
Synchronous Phasor Monitoring: Supports wide-area monitoring (PMU) for assessing grid stability by transmitting accurate, time-synchronized phasor data.
