It provides a 1300 nm single‑mode LASER interface for deterministic relay‑to‑relay data transfer and channel‑health diagnostics.\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\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eUR 7DH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eGeneral Electric Multilin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eMarkham, Ontario, Canada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003eapprox. 1.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003eapprox. 6 in L, 7 in W, 1.5 in H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating Temp\u003c\/th\u003e\n\u003ctd\u003enot specified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Consumption\u003c\/th\u003e\n\u003ctd\u003eUR backplane supplied (value not specified)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCore Performance Indicators\u003c\/th\u003e\n\u003ctd\u003e1300 nm single‑mode LASER channel; Tx1\/Rx1 top‑position orientation; integrated channel monitoring; UR Series backplane interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProfinet \/ EtherNet\/IP Deterministic Networks\u003c\/h3\u003e\n\u003cp\u003eThe UR-7DH aligns with GE industrial control conventions for deterministic communication behavior across relay networks. Although the module uses fiber‑optic LASER signaling rather than Ethernet, its internal UR backplane communication follows fixed‑cycle deterministic timing similar to GE’s Profinet\/EtherNet\/IP‑based control architectures. Channel‑health monitoring suppresses cross‑module latency variations, and firmware flash compatibility across UR relay families ensures stable communication without requiring protocol‑layer adjustments.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the UR‑7DH be hot‑swapped in a UR chassis? A: No. Inter‑relay communication modules require the relay to be de‑energized before insertion or removal to maintain optical interface integrity and prevent backplane communication faults.\u003c\/p\u003e\n\u003cp\u003eQ: Does the UR‑7DH support dual‑channel communication? A: No. The 7D order option provides a single LASER channel only. Other type‑7 modules may include dual channels.\u003c\/p\u003e\n\u003cp\u003eQ: Is the chassis shape standard across UR modules? A: The UR‑7DH uses a modified chassis with a clipped corner, which differs from the standard rectangular profile used by other UR modules.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaintain minimum bend radius for single‑mode fiber to avoid attenuation on the 1300 nm LASER channel.\u003c\/li\u003e\n\u003cli\u003eEnsure Tx1 and Rx1 ports are correctly aligned with the corresponding remote relay ports.\u003c\/li\u003e\n\u003cli\u003eClean fiber connectors before installation to prevent signal degradation.\u003c\/li\u003e\n\u003cli\u003eAvoid routing fiber cables near high‑voltage conductors to minimize mechanical stress and accidental damage.\u003c\/li\u003e\n\u003cli\u003eVerify module seating by applying uniform pressure across the connector edge before energizing the relay.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":48167601012926,"sku":"UR7DH","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/general-electric-ur7cv-multilin-comms-module-2alevre2p0i.png?v=1759055888","url":"https:\/\/www.autooiltech.com\/es\/products\/ur-7dh-ge-multilin-inter-relay-communications-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
