Profinet / EtherNet-IP Deterministic Networks and I/O Density Scaling

The UR6GV module extends the Universal Relay hardware architecture by increasing discrete signal handling capacity through additional digital input and output channels. The opto-isolated input circuits provide electrical separation between field contact signals and relay logic processing. The module supports configurable I/O density scaling within UR chassis configurations, allowing additional status monitoring points and control outputs to be integrated into protection and automation schemes.

The output section provides direct contact switching for breaker control, trip circuits, alarm functions, and interlocking logic. The latching output channels maintain defined states during loss of relay power for applications requiring retained lockout or memory functions.

Frequently Asked Questions

Q: Can the UR6GV module be installed in any UR relay slot?
A: The UR6GV is installed in compatible Universal Relay chassis positions. Slot assignment depends on the specific relay hardware configuration and ordering arrangement.

Q: Does the UR6GV provide electrical isolation between field signals and internal relay circuits?
A: Yes. The digital input channels use opto-isolated circuits, and the module specifies 2000 V AC dielectric withstand isolation between inputs, outputs, and internal logic.

Q: Are the output contacts suitable for direct breaker control applications?
A: The module provides Form-A and Form-C contact outputs with specified current and switching ratings for control and trip circuit applications within the UR protection platform.

Field Installation Guidelines

• Install the UR6GV module into the designated Universal Relay chassis slot according to the relay hardware configuration.
• Verify the relay power supply and chassis grounding connections before inserting or removing the module.
• Route field contact wiring separately from high-voltage power conductors to reduce induced noise.
• Use appropriate shield grounding practices for control wiring where electromagnetic interference is present.
• Confirm digital input voltage levels before connection to ensure compatibility with the selected 17 to 300 V DC input range.
• Verify output contact wiring against the protection scheme drawings before energizing breaker trip or control circuits.
• Follow manufacturer procedures for module replacement, firmware compatibility checks, and relay configuration verification.
