It serves as the physical chassis and high-speed backplane backbone required to house a central CPU, power supply unit, and compatible expansion I\/O modules within a unified local assembly.\u003c\/p\u003e\n\u003ch3\u003eSystem Bus Interconnect and Slot Architecture\u003c\/h3\u003e\n\u003cp\u003eThe chassis features 11 module slots with an integrated System Bus (SYSBUS) backplane assembly. The SYSBUS routes power distribution, control signaling, and parallel data transfer across installed card positions. The primary slots accommodate the main controller module and power supply, while remaining slots support high-density 800 Series discrete, analog, and specialty I\/O modules.\u003c\/p\u003e\n\u003ch3\u003eMainframe Configuration vs Remote Primary Housings\u003c\/h3\u003e\n\u003cp\u003eUnlike remote drop housings (such as the AS-H827-103), the \u003cstrong\u003eAS-H827-209\u003c\/strong\u003e is wired specifically as a mainframe primary housing. Its internal backplane traces include dedicated CPU signal paths and system bus routing required for local PLC operations. This structural design ensures deterministic module scanning and communication between the central processor and local I\/O cards without requiring additional drop adapters.\u003c\/p\u003e\n\u003ch3\u003eSystem 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\u003eAS-H827-209\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric (Modicon)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePLC Racks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eModicon 984 \/ 800 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Configuration\u003c\/td\u003e\n\u003ctd\u003eMainframe Primary Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Bus\u003c\/td\u003e\n\u003ctd\u003eSystem Bus (SYSBUS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Capacity\u003c\/td\u003e\n\u003ctd\u003e11 Slots (27-inch chassis)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eIndustrial Panel Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Dimensions\u003c\/td\u003e\n\u003ctd\u003e27.0 in length (approx. 68.6 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApproximate Weight\u003c\/td\u003e\n\u003ctd\u003e18.0 lbs (approx. 8.17 kg)\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 functional difference between the AS-H827-209 and the AS-H827-103 housing?
