Main Features and Advantages
The GE URRHH delivers a combination of electrical performance and intelligent monitoring that addresses the operational realities of modern protection systems. Its high-range input capability accommodates both DC station battery voltages and AC auxiliary supplies, providing installation flexibility across varied substation configurations. The module’s 35 W output capacity sufficiently powers the UR relay’s internal processing logic while maintaining adequate headroom to energize connected dry-contact input circuits without requiring external auxiliary power sources.
Integrated self-diagnostic functionality: The GE URRHH distinguishes itself through continuous health monitoring executed in coordination with the UR relay’s self-testing architecture. The system performs primary and secondary integrity assessments, evaluating hardware functionality and automatically de-energizing the power supply upon detection of critical failure conditions. This proactive protection mechanism prevents fault propagation and provides maintenance teams with actionable diagnostic data through the relay’s event logging system.
Visual status reporting: Faceplate LEDs on the GE URRHH provide immediate, software-independent indication of module health. Three distinct states—continuous ON for normal operation, ON/OFF cycling for warning or minor fault conditions, and OFF for de-energized or critical failure states—enable rapid visual assessment during routine inspections or troubleshooting procedures. This straightforward interface reduces diagnostic time and minimizes reliance on configuration software access.
Robust environmental construction: The GE URRHH is housed in a black matte finish enclosure designed for protection against environmental contaminants commonly encountered in electrical control rooms and outdoor cabinets. The module operates reliably across a temperature range of −20°C to +70°C, ensuring consistent performance in both climate-controlled enclosures and less regulated environments. The 4 A / 250 V internal fuse provides essential circuit protection without requiring external fusing components, simplifying panel design and reducing installation complexity.
