Schneider Electric AS-H827-103 Modicon 11-Slot PLC
The Schneider Electric AS-H827-103 is a 27-inch, 11-slot primary rack housing designed for legacy Modicon 800 Series Programmable Logic Controller (PLC) systems. It provides the structural chassis and internal backplane bus interface required to house a central processor or remote drop adapter alongside up to ten discrete, analog, or specialty 800 Series I/O modules.
Backplane Interconnect and Slot Allocation
The chassis features 11 module positions across a 27-inch width frame. The integrated printed circuit backplane delivers parallel logic bus communication and DC power distribution to all installed cards. The primary slot typically hosts the drop processor or main power/controller module, while the remaining slots support high-density 800 Series input/output expansion modules.
Mechanical Construction and Installation
Engineered for panel-mount installation in industrial enclosures, the heavy-duty housing protects internal electronics from mechanical stress and vibration. Mechanical alignment tracks ensure precise alignment between individual module edge connectors and backplane bus sockets, reducing contact wear and preventing pin misalignment during module installation or maintenance.

Frequently Asked Questions
Q: What is the main structural difference between the AS-H827-103 and smaller 800 Series racks?A: The AS-H827-103 utilizes a wide 27-inch chassis that provides 11 total slots, accommodating larger I/O configurations compared to 7-slot (19-inch) or 4-slot (10-inch) housings.
Q: Can the AS-H827-103 primary housing be substituted directly with an AS-H827-209 housing? A: No. The H827-103 is engineered specifically as a remote I/O primary housing, whereas the H827-209 has distinct backplane wiring and processor routing dedicated to mainframe PLC processor setups.
