It provides internal system bus connectivity between a primary CompactBlock base unit and adjacent CompactBlock expansion modules. Supplied in a package of 5 pieces, this flexible ribbon cable enables compact side-by-side module interconnection inside panel enclosures without requiring external terminal wiring.\u003c\/p\u003e\n\u003ch3\u003eSystem Interconnection and Bus Communication\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1790-15CMCBL\u003c\/strong\u003e carries high-speed system bus communication signals and internal logic power from the main CompactBlock I\/O base block to expansion I\/O blocks. Its 15 cm length provides sufficient slack for proper positioning and alignment of adjacent DIN rail mounted blocks while maintaining minimal signal latency and low noise susceptibility across the expansion bus.\u003c\/p\u003e\n\u003ch3\u003eInstallation and Physical Specification\u003c\/h3\u003e\n\u003cp\u003eFeaturing pre-molded multi-pin ribbon connectors at both ends, the cable plugs directly into the designated expansion ports on the side housing of CompactBlock I\/O modules. Keyed connector housings prevent reversed insertion, ensuring correct pin alignment during installation or module maintenance. The ribbon cable construction accommodates clean wire routing in tight control cabinets.\u003c\/p\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\u003e1790-15CMCBL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDistributed I\/O Expansion Cables\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e1790 CompactBlock I\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e15 cm (0.15 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Quantity\u003c\/td\u003e\n\u003ctd\u003e5 pieces per pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003eMulti-pin pre-molded ribbon connectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eBus interconnection for CompactBlock I\/O expansion modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.02 lbs (0.01 kg) per cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary function of the 1790-15CMCBL expansion cable?
