GE Multilin UR Platform Communication and I/O Compatibility
The UR6CV CT/VT Module is designed for integration with GE Multilin Universal Relay systems through the relay chassis backplane interface. The module processes analog current transformer and voltage transformer signals for relay measurement functions.
Moreover, GE UR series modules support modular I/O density scaling through chassis-based configurations. The UR6CV maintains firmware flash compatibility with supported Universal Relay platforms and exchanges measurement data through the internal relay architecture.
The module provides four current measurement channels and three voltage channels, allowing phase voltage acquisition through VA, VB, and VC inputs. Therefore, it supports protection element calculations requiring synchronized electrical parameter sampling.

Field Installation Guidelines
- Install the UR6CV module only in compatible GE Multilin Universal Relay chassis positions.
- Verify CT and VT wiring polarity before connecting external measurement circuits.
- Use shielded signal wiring where required by the installation environment and terminate shields according to site grounding practices.
- Separate low-level measurement wiring from high-energy switching circuits to reduce electrical interference.
- Confirm current transformer secondary circuits are correctly terminated before energizing the relay system.
- Check module seating and backplane connection integrity before system commissioning.
