Description
Product Overview
GE Multilin UR6PH is a hot-swappable digital I/O expansion module designed for the GE Vernova Multilin UR series universal protection relays. It provides extra opto-isolated digital input channels and Form‑A relay outputs to extend substation control, interlocking and alarm functions for UR family relays including G60, T60, D60, F60 and M60. It adds contact control and status feedback for circuit breakers, disconnect switches, alarm annunciators and auxiliary substation devices. Widely used in power substations, power plants and industrial power distribution systems, this module is commonly stocked as spare replacement hardware for existing UR relay installations.

Key Features
- 4 opto-isolated digital inputs + 6 Form‑A relay outputs for substation auxiliary control and interlock logic
- Built-in current monitoring on each relay output to detect coil/load faults
- Hot-swappable plug-in design; replaceable without removing main relay from service
- Supports GOOSE messaging, sequence of event (SOE) timestamping for fault analysis
- Front panel LED indicators for channel status, module health and fault alarm
- Software configurable via EnerVista UR without hardware DIP switch changes
- High isolation rating to protect protection relay core circuitry from field surge and noise
Installation & Testing Notes
- Insert UR6PH into the designated expansion slot of UR series relay chassis
- Terminate field wiring for DI and relay outputs, verify contact load derating for inductive loads
- Check wiring insulation and confirm no short circuits before energizing substation control power
- Configure channel assignment and logic mapping via EnerVista UR setup software
- After configuration, run module self-test and validate each DI status and relay output operation
- Hot swap is supported when host relay remains powered; confirm relay is not in critical trip state before replacement
- Perform contact output test and SOE logging verification during commissioning and routine maintenance
