    GE UR6UH Digital I/O Module (Multilin UR Series)
    Manufacturer: GE Multilin / General Electric
    Model: UR6UH
    Series: Multilin UR (Universal Relay)
    Type: Digital Input/Output (I/O) Module
    Function: Monitoring & control of auxiliary equipment in power systems
    1. Overview
    The GE UR6UH is a **high‑density digital I/O module** for the GE Multilin UR series protection relays. It provides 6 digital inputs and 6 Form‑A (normally open) relay outputs, designed for monitoring status and controlling auxiliary devices in substations and industrial power systems. It features high‑speed response, optical isolation, and direct integration with UR relay backplanes.
