Description

The UR-8FH module from General Electric Multilin is a specialized CT/VT (Current Transformer/Voltage Transformer) module, engineered for installation within the Universal Relays series. 

Technical Specifications

• Manufacturer: General Electric Multilin
• Manufacturing Location: Markham, Ontario, Canada
• Weight: 2 lb, 9 oz
• Dimensions: Approx. 15 cm L x 18 cm W x 4 cm H

Key Features

• Current Transformers (CT):
  • Provides 3 x 1A/5A phase current transformers.
  • Includes 1A/5A ground current transformers.
• Voltage Transformers (VT):
  • Offers four voltage transformer terminals.
  • Capable of scaling down current and voltages to manageable levels for relay monitoring and control.

Functionality:

• Channel Configurations:
  • The module allows for the use of voltage or contact inputs on channels one through four or channels five through eight.
  • Specific connections for each channel:
    • Channels one and five: Phase A
    • Channels two and six: Phase B
    • Additional channels are similarly configured, as outlined in the UR manuals.
• Safety and Installation Guidelines:
  • The UR manuals provide detailed instructions for proper relay connections, including the importance of matching the nominal current (1 A or 5 A) to the secondary rating of the connected CTs.
  • Failure to follow these guidelines may result in system damage.
