Industrial Control Network and I/O Processing Features
The UR 4DH module operates as a configurable digital interface component within the GE Multilin UR Series relay architecture. It processes discrete field signals from external devices and transfers status information to relay logic functions.
The module supports digital input handling for protection schemes, breaker status monitoring, alarm circuits, interlocking logic, and supervisory control interfaces. GE UR platform configurations can combine multiple digital I/O modules to increase signal density, supporting system designs requiring expanded input and output channels.
The module architecture supports GE industrial control requirements including backplane communication velocity licensing, I/O density scaling, and firmware flash compatibility within supported UR relay configurations. These functions allow digital signal expansion without changing the primary relay processing platform.

Field Installation Guidelines
Install the UR 4DH module according to the GE Multilin UR Series hardware configuration requirements.
Verify the relay chassis slot assignment before insertion and confirm that field wiring matches the configured digital input voltage range. Maintain proper separation between low-level signal wiring and high-voltage switching circuits to reduce electrical interference.
Use appropriate terminal grounding practices and verify cable shielding connections according to the site electrical design. Check module status indicators and relay configuration parameters after installation to confirm correct digital input recognition.
