GE Multilin UR6DV – Digital I/O Input Module | Universal Relay Platform
Engineering Background: The GE Multilin Universal Relay (UR) series represents GE Grid Solutions’ flagship protection and control platform, deployed across transmission substations, generation facilities, and industrial power systems worldwide. The UR platform’s modular architecture allows engineers to configure relay functionality precisely to application requirements — eliminating over-specification and reducing lifecycle cost.
Product Positioning: The UR6DV is a dedicated Digital I/O module designed for the UR chassis. It expands the relay’s digital input and output capacity, enabling integration with external switching devices, SCADA systems, and interlocking circuits. This module is essential for complex protection schemes requiring high channel density and deterministic response times.

- Wide DC Input Range: Field-selectable voltage thresholds accommodate diverse substation battery bus standards.
- Hot-Swap Compatible: UR chassis architecture supports module replacement without full system de-energization (verify with site safety procedures).
- Backward Compatible: Interoperable with existing UR chassis generations — protects prior capital investment.
System Architecture & Signal Flow
The UR6DV installs into any available I/O slot of a UR chassis (3U or 6U form factor). Digital input signals from field devices (auxiliary contacts, pushbuttons, SCADA outputs) are optically isolated and conditioned before being passed to the UR CPU module via the chassis backplane. The CPU processes logic equations and protection elements in real time, then drives output commands back through the UR6DV’s relay output contacts to trip coils, alarms, or interlocking circuits. All I/O states are time-stamped and logged for post-event analysis via the UR’s onboard event recorder.

Technical FAQ
Q: Is the UR6DV compatible with all UR chassis generations?
A: The UR6DV is designed for the GE Multilin UR platform. Compatibility depends on chassis firmware version — contact us with your chassis model for confirmation.
Q: Can the digital inputs be configured for both wet and dry contacts?
A: Yes. Input thresholds are field-configurable via UR Setup software to accommodate both wet (voltage-sourced) and dry (voltage-free) contact types.
Q: What is the warranty on refurbished units?
A: Refurbished UR6DV modules carry a 12-month functional warranty. New sealed units carry the standard GE Multilin warranty.
Q: Do you provide IEC 61850 configuration support?
A: Yes. Our engineering team can assist with SCL/CID file configuration for IEC 61850 GOOSE integration — inquire at time of order.
Q: What is the lead time for in-stock units?
A: In-stock units ship within 1–3 business days. Out-of-stock lead times vary by sourcing channel — typically 2–6 weeks.
