The module exchanges processed measurement data through the UR chassis backplane interface and maintains compatibility with the host relay firmware environment. The modular design supports I\/O density scaling through chassis-based hardware configuration and allows integration with UR protection functions including differential, distance, overcurrent, and voltage measurement applications.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What signal types are accepted by the UR8LM module?\u003cbr\u003eA: The UR8LM accepts analog electrical inputs from 4 CT channels and 4 VT channels for current and voltage measurement processing within the host UR relay.\u003c\/p\u003e\n\u003cp\u003eQ: Can the UR8LM operate as a standalone protection device?\u003cbr\u003eA: No. The UR8LM is an input module designed for installation in a GE Multilin Universal Relay chassis and requires a compatible UR host device for processing and communication functions.\u003c\/p\u003e\n\u003cp\u003eQ: What environmental conditions are specified for UR8LM operation?\u003cbr\u003eA: The specified operating temperature range is -40 deg C to +70 deg C. Additional environmental parameters depend on the complete UR relay system installation.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the UR8LM only in compatible GE Multilin Universal Relay chassis positions. Verify module seating, chassis backplane contact alignment, and connector engagement before applying power.\u003c\/p\u003e\n\u003cp\u003eUse appropriate shielded wiring practices for CT and VT signal connections. Maintain separation between analog measurement wiring and high-current switching conductors to reduce electromagnetic interference.\u003c\/p\u003e\n\u003cp\u003eConfirm CT secondary circuit conditions before removal or installation procedures. Follow site protection procedures for energized current transformer circuits.\u003c\/p\u003e\n\u003cp\u003eVerify host relay configuration, firmware compatibility, and communication settings after module installation. Validate analog channel assignments through the relay configuration interface before placing the protection system into service.\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":44497817469016,"sku":"UR8LM","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/UR8MH.jpg?v=1785829406","url":"https:\/\/www.industriaxplc.com\/products\/ge-multilin-ur8lm-ur-8lm-ct-vt-analog-input-module","provider":"IndustriaX Limited","version":"1.0","type":"link"}
