Product Overview

The GE Multilin UR-67H (12A0-0006-C6) functions as a high-density executive interface for the Universal Relay (UR) platform. This expansion module provides 8 independent Form-A (Normally Open) relay outputs designed for critical substation operations, including circuit breaker tripping, closing commands, and auxiliary alarm logic. We supply this module as 100% Brand New and Original, ensuring your protection system—whether it be a B30, C30, D60, or G60—operates with the high-speed switching and utility-grade reliability required for fault clearance and power system stability.

Engineering Advantages

  • High-Current Breaker Interfacing: The UR-67H handles a "Make and Carry" current of 30 A for short durations (0.2 seconds). This allows the module to directly energize heavy-duty circuit breaker trip coils without the need for interposing relays, reducing the total fault clearing time and simplifying cabinet wiring.

  • Electromagnetic Resilience: Utility environments generate significant EMI during switching events. This module features a 2000 VAC dielectric strength rating, which isolates field-side transients from the sensitive microprocessor logic. This barrier prevents nuisance trips and hardware damage during severe grid disturbances.

  • Extreme Environmental Endurance: Engineered for the "Extreme Utility Grade" standard, the UR-67H operates flawlessly from –40°C to +85°C. This thermal resilience permits installation in unconditioned substation kiosks and remote switchgear rooms across diverse geographical climates.

  • Seamless EnerVista Integration: The module integrates fully with the EnerVista UR Setup software. This allows engineers to map outputs to internal logic variables—such as overcurrent elements or bus differential trips—with millisecond-level precision using logic gates and timers.

  • Mechanical Security: The plug-in design features robust locking mechanisms for the 6U UR chassis. This ensures that electrical contacts remain intact even in high-vibration substation environments, such as those located near heavy-duty power transformers or reactors.

FAQs

  • Does the UR-67H support contact monitoring?

    No, the UR-67H (12A0-0006-C6) provides non-monitored dry contacts. If your application requires Trip Circuit Monitoring (TCM) to supervise the continuity of the trip coil, you should consider UR modules with "M" or "S" designations in the output configuration.

  • Can I use the UR-67H in any UR series relay?

    Yes. The UR-67H is a universal module compatible with the entire GE Multilin Universal Relay family, including the B30, C30, D30, D60, G30, G60, L30, L60, L90, M60, N60, and T60, provided there is an available I/O slot in the chassis.

  • How does the module perform during high-inductive breaking?

    The UR-67H features contacts optimized for high-inductive loads. However, for highly inductive DC trip circuits, we recommend using external surge suppression or ensuring the load falls within the module's DC breaking capacity specifications to maximize contact life.

  • What is the benefit of purchasing a "Brand New" module versus refurbished?

    Protective relaying is a "fail-safe" requirement. Used or refurbished modules may have contact pitting from previous switching events or degraded dielectric barriers. A 100% Brand New UR-67H ensures the contact resistance is at factory minimums, guaranteeing reliable operation during a genuine power system fault.
