Description
The GE Multilin UR-6TH (UR6TH) is a modular digital input/output (I/O) expansion module designed specifically for the Universal Relay (UR) series platform. Engineered for critical power utility substations and industrial protection systems, it provides reliable signal conditioning, discrete monitoring, and high-speed tripping capabilities to safeguard transformers, generators, and distribution feeders.
📋 Technical Specifications Datasheet
- Brand: GE Multilin (General Electric / Alstom / Grid Solutions)

⚙️ Operating Norms and Usage
- Always adhere to strict electrostatic discharge (ESD) safety protocols, utilizing a properly grounded wrist strap when handling or installing the module.
- Insert the module smoothly into its designated slot within the UR chassis backplane, ensuring complete board alignment before securing fastening hardware.
- Verify all field wiring, control power levels, and terminal block screw torques against system schematic drawings prior to energization.
⚡ Power-On / Power-Off Sequence
- Power-On Sequence: Confirm that all rear terminal blocks and communication links are securely terminated, energize the main relay control power supply, and observe the front-panel relay display and diagnostic LEDs for normal self-test and module recognition.
- Power-Off Sequence: Isolate associated trip and control circuits to prevent inadvertent actuation, power down the relay chassis power supply, and allow complete internal capacitor discharge before servicing or extracting the module.
📖 Product Usage Instructions
- Use GE EnerVista UR software to configure input debounce timers, map programmable logic (FlexLogic), and assign output states for the UR-6TH module.
- Continuously monitor module status through the relay’s front-panel HMI or SCADA network interface to verify healthy communication and active loop status.
- Leverage the modular architecture to replace or upgrade I/O slots seamlessly when system expansion or maintenance is required.
❓ Common Questions & Answers Q&A
- Q: What is the specific configuration of the UR-6TH I/O module?
A: The UR-6TH features a specific combination of digital inputs and Form-A outputs (typically 4 Form-A non-monitoring outputs and 8 contact inputs, depending on the exact sub-variant order code) built to handle fast control actions.
- Q: Can this module be hot-swapped in a UR relay chassis?
A: It is recommended to de-energize the relay chassis prior to inserting or removing internal modules to prevent electrical transients or configuration errors.
