Configured for contact‑signal interfacing in Universal Relay (UR) protection platforms, the GE UR‑6DH (UR 6DH digital I/O module) provides sixteen Form‑C contact inputs and outputs for system‑level control, tripping, and interlocking. It integrates with UR‑series frames to deliver modular digital‑I/O expansion without additional hardwiring.

Within UR‑series architectures, the UR 6DH aligns with deterministic relay‑logic timing required for synchronous digital‑signal processing. Its Form‑C contact paths maintain stable propagation intervals for protection and interlocking functions. I/O density scaling is achieved through modular UR frame configuration, while firmware flash compatibility resides entirely at the relay CPU level; the UR‑6DH hardware characteristics remain fixed across all variants.
Frequently Asked Questions
Q: What type of contacts does the UR‑6DH provide? A: The module provides only Form‑C contacts. Users requiring Form‑A or fast Form‑C contacts must select a different UR digital‑I/O module.
Q: How is the UR‑6DH configured? A: Configuration and diagnostics are performed through EnerVista UR software, which offers Viewpoint Monitoring and Viewpoint Maintenance tools.
Q: What role does digital I/O play in UR relays? A: Digital I/O modules provide variable contact inputs and outputs for protection schemes, tripping logic, interlocking, and auxiliary control across UR‑series applications.
Field Installation Guidelines
Ensure the module is fully seated in the UR frame to maintain deterministic contact‑signal timing.
Maintain separation between digital‑I/O wiring and CT/VT cabling to reduce noise coupling.
Bond shielded cables at a single termination point to avoid ground‑loop formation.
Verify correct contact‑type requirements (Form‑C only) before installation.
Inspect connectors for proper engagement prior to energizing the relay.
