The unit utilizes an industrial-grade microprocessor paired with flash memory and onboard RAM to drive high-speed computation for feeder, generator, transformer, and motor protection algorithms. Operating on dual power options of 24-48 VDC or 110\/220 VAC, the standard 38 mm module integrates three 10\/100\/1000Base-T Ethernet ports alongside one RS-485 serial port to execute continuous real-time data processing and SCADA network communication.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eUR9WH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Multilin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e200 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e38 mm thickness (standard UR slot width)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24-48 VDC \/ 110\/220 VAC dual power input capability\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor \u0026amp; Memory\u003c\/td\u003e\n\u003ctd\u003eIndustrial-grade microprocessor, onboard flash memory, high-speed RAM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interfaces\u003c\/td\u003e\n\u003ctd\u003e3 x Ethernet ports (10\/100\/1000Base-T), 1 x RS-485 serial port\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eGE Multilin UR Series protection relay chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity and Firmware Flash Compatibility\u003c\/h3\u003e\n\u003cp\u003eThe GE Multilin UR9WH manages backplane bus communication velocity across the internal UR chassis architecture. The integrated microprocessor verifies firmware flash compatibility during startup and maintains high-speed data exchange between adjacent protection, metering, and I\/O modules. By maintaining deterministic network arbitration across its three gigabit Ethernet channels, the CPU prevents communication packet congestion during high-density event logging and real-time protection trip processing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the UR9WH CPU module interface with existing UR series chassis hardware?\u003c\/p\u003e\n\u003cp\u003eA: The module installs directly into the standard 38 mm central processing slot of any GE Multilin UR series chassis, establishing immediate connection with the backplane power and communication buses.\u003c\/p\u003e\n\u003cp\u003eQ: What network interface options are available for SCADA integration?\u003c\/p\u003e\n\u003cp\u003eA: The board provides three 10\/100\/1000Base-T Ethernet ports for redundant network architectures along with one RS-485 serial port for legacy protocol integration.\u003c\/p\u003e\n\u003cp\u003eQ: How are firmware updates managed on the CPU module?\u003c\/p\u003e\n\u003cp\u003eA: Firmware images load directly into onboard flash memory via network connections or service software without interrupting physical board calibration or user configuration settings.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eField technicians must observe the following physical and electrical procedures during module insertion:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDe-energize the UR relay chassis power supply before attempting module installation or removal to prevent electrical arc damage to backplane connectors.\u003c\/li\u003e\n\u003cli\u003eSlide the 38 mm module evenly along the chassis guide rails until the rear multi-pin connector seats firmly into the backplane socket.\u003c\/li\u003e\n\u003cli\u003eTighten the top and bottom captive retaining screws to secure the module chassis and ensure frame ground continuity.\u003c\/li\u003e\n\u003cli\u003eConnect 10\/100\/1000Base-T Ethernet cables to the front RJ-45 ports, ensuring minimum bend radius clearance inside the cabinet door.\u003c\/li\u003e\n\u003cli\u003eVerify that power input wiring matches the selected voltage supply range (24-48 VDC or 110\/220 VAC) prior to re-energizing the chassis.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":43871051415651,"sku":"UR9WH","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/354_51b362dd-d282-4249-be91-0731b1459855.jpg?v=1764832546","url":"https:\/\/www.autocontrolglobal.com\/products\/relay-cpu-module-ge-multilin-ur9wh-universal","provider":"AutoControl Global","version":"1.0","type":"link"}
