Product Overview
The UR6HH serves as a high-density interface module for the GE Multilin Universal Relay (UR) ecosystem, including the B30, C30, D60, and G60 platforms. This card facilitates the critical bridge between protection logic and substation field equipment. It features 16 discrete digital inputs for comprehensive system state monitoring and 8 high-capacity relay outputs engineered for high-speed circuit breaker tripping and closing operations. We provide this module as 100% Brand New and Original, ensuring your protection schemes operate with the millisecond accuracy required for utility-grade power systems.

Engineering Advantages
-
Substation-Hardened Design: The UR6HH excels in electromagnetically noisy environments. Integrated transient suppression protects the internal relay processor from high-voltage surges and switching transients common in HV/MV substations.
-
High-Speed Trip Execution: The 8 relay outputs utilize high-capacity electromechanical components designed specifically for "Fast-Trip" logic. This ensures the relay executes breaker commands in milliseconds, minimizing equipment damage during fault conditions.
-
Configurable Logic Mapping: Using the EnerVista UR software suite, engineers map the 16 digital inputs to specific protection elements or Sequence of Event (SOE) recorders. This flexibility allows for detailed post-fault analysis and complex interlocking schemes.
-
Optimized Thermal Range: The module operates within an industrial-hardened range of -40 °C to +60 °C. This makes the UR6HH suitable for unheated outdoor kiosks and extreme climate power generation sites.
-
Modular Hot-Swap Ready: The UR modular architecture allows for straightforward hardware upgrades. The UR6HH slides into designated slots in the UR chassis, allowing for rapid expansion of I/O capacity without replacing the entire protection relay.
FAQs
-
Can I use the UR6HH in a 125VDC control circuit?
No. The UR6HH is specifically designed for 24VDC nominal logic levels. If your substation utilizes a 125VDC or 250VDC battery bank for control logic, you must select the appropriate high-voltage I/O variant (such as the UR6L or similar) to prevent module damage.
-
How do I configure the input thresholds?
You configure the pickup and dropout thresholds via the EnerVista UR Setup software. For a 24V nominal system, the software typically sets the threshold between 17V and 19V to ensure positive state detection while ignoring stray induced voltages.
-
Does this module support Sequence of Events (SOE) recording?
Yes. The UR6HH inputs support millisecond-accurate time-stamping. When an input changes state, the UR system logs the event in its non-volatile memory, providing a precise timeline for fault investigations.
-
Is the UR6HH compatible with the older SR series relays?
No. The UR6HH is exclusively compatible with the Universal Relay (UR) modular platform. It will not fit or function in the older SR (750/760) series relays.
