Firmware Flash Compatibility and Backplane Integration

The UR-1HH power module interfaces with the Universal Relay chassis power architecture to supply regulated voltages for CPU cards, digital I/O modules, communication boards, and field contact circuits. The modular design supports I/O density scaling by allowing dual power supply installation configurations within compatible UR relay chassis. Firmware flash compatibility depends on the installed relay platform and associated hardware revision.

Frequently Asked Questions

Q: Can the UR-1HH be installed in a redundant power supply configuration?
A: Yes. The module supports dual power supply arrangements using compatible Slot 1A and Slot 1B chassis positions for redundant relay power configurations.

Q: Does the UR-1HH provide power for external field contacts?
A: Yes. The module provides isolated voltage output for powering external dry-contact input circuits connected to the relay system.

Q: Is the UR-1HH a hot-swappable module?
A: The module uses a slide-in chassis mounting design with release clips. Maintenance procedures must follow the relay system installation requirements before module removal or insertion.

Field Installation Guidelines

• Install the UR-1HH only in the designated power supply slot locations of compatible GE Multilin Universal Relay chassis.
• Verify auxiliary AC or DC input wiring before energizing the module.
• Maintain separation between power wiring and low-level signal wiring to reduce electrical interference.
• Connect cable shields according to the relay panel grounding practice and site electrical standards.
• Confirm connector seating and mechanical retention clips are fully engaged after installation.
• Inspect fuse condition and terminal wiring integrity during maintenance activities.
