It provides local signal backplane connectivity between a primary CompactBlock LDX base module and an expansion I\/O module. Measuring 15 cm in length, this extended ribbon cable allows maintenance and control system engineers to position adjacent expansion modules with up to 7 cm (2.76 in.) of physical separation on standard DIN rails, simplifying panel wire routing and thermal management in high-density control enclosures.\u003c\/p\u003e\n\u003ch3\u003eExtended Distance Inter-Module Connectivity\u003c\/h3\u003e\n\u003cp\u003eIn standard CompactBlock LDX distributed I\/O layouts, base units connect directly to expansion blocks via standard short interconnects. The \u003cstrong\u003e1790-15CMCBL\u003c\/strong\u003e addresses spatial constraints inside enclosure layouts where components cannot be mounted immediately side-by-side. The 15 cm flexible ribbon cable transfers internal communication logic and power buses between the base block and the extension block without degradation, ensuring seamless integration within DeviceNet and other supported fieldbus architectures.\u003c\/p\u003e\n\u003ch3\u003eStructural Specifications \u0026amp; Pack Quantity\u003c\/h3\u003e\n\u003cp\u003eConstructed with industrial-grade flat ribbon cabling and factory-terminated connectors, the \u003cstrong\u003e1790-15CMCBL\u003c\/strong\u003e ensures secure multi-pin alignment with low insertion resistance.
