GE Multilin UR-8LH CT/VT Module

Description:

The GE Multilin UR-8LH is a CT/VT module designed for use with the Universal Relay series. It can replace existing modules, upgrade current modules, or provide new capabilities to relays that originally did not include this module. The UR-8LH supplies the relay with 4 CT (Current Transformers) and 4 VT (Voltage Transformers), featuring enhanced diagnostic capabilities.

Technical Specifications：

• Model Number: UR-8LH
  
• Manufacturer: General Electric Multilin (GE)
  
• Dimensions: Approximately 6” L x 7” W
  
• Weight: 2 lb 9 oz

Key Features:

• Enhanced Diagnostics: The module includes advanced diagnostic capabilities that verify the integrity of analog signals, ensuring their reliability. An advanced algorithm is used to assess whether the signals are operating properly.
• Signal Scaling: CT/VT transformers reduce current and voltage values to levels that the relay can handle, allowing for accurate calculations of current and voltage ratios. This is crucial for detecting hazardous voltage and current conditions and determining an appropriate response.
• Data Display: Diagnostic data can be viewed via the liquid-crystal display on the front faceplate or through a computer using the EnerVista UR software.
