    GE UR6PH UR Series Digital I/O Expansion Module (GE Multilin Substation Protection Relay Accessory)
    Manufacturer: GE Multilin (General Electric Grid Solutions)
    Model: UR6PH (UR universal relay series I/O daughter card)
    Matching Host: All GE UR series multifunction protection relays (UR30, UR50, UR70, UR80, UR90 etc.)
    Type: Rack pluggable digital I/O extension module, 4 isolated DI + 6 Form-A relay DO, optional voltage/current metering option
    Core Function: Collect circuit breaker/disconnector position dry contact signals; drive trip/close coil, alarm horn, fault indicator light via relay contacts; support substation GOOSE interlock, Modbus TCP data upload; full channel self-diagnosis for open/short circuit faults, expand point capacity of main protection relay
    1. Product Overview
    UR6PH is an expandable I/O daughter card exclusively for GE UR series universal power protection relays, installed via internal rack slot of the main relay unit to expand digital signal access and control output capacity. It carries 4 independent galvanically isolated digital input channels for picking up on-site switchgear dry contact status (breaker position, earthing switch, fault trip feedback). Six Form-A single-pole normally open relay outputs are used to directly control trip coils, alarm devices and auxiliary interlock circuits. Optional built-in sampling circuit supports auxiliary voltage/current measurement for auxiliary loop monitoring. The module integrates triple industrial Ethernet ports, native support for IEC 61850 GOOSE substation interlock communication and Modbus TCP industrial Ethernet protocol, realizing fast cross-device logic interlock in intelligent substation. All channels adopt surge suppression and ESD protection, wide temperature industrial hardware design, suitable for high electromagnetic interference environment of power distribution room. GE official discontinued production, only refurbished and surplus new spare parts available in aftermarket, widely used in thermal power, hydropower, petrochemical power distribution substation protection systems.
