Schneider ASH827209 PLC Rack | 16 Slot 19-Inch Chassis

The ASH827209 serves as a chassis backplane for Schneider PLC modules. This rack provides mechanical support and electrical connections for all system cards. Its rectangular frame measures 480 millimeters in width. The rack height reaches 260 millimeters exactly. Depth stays at 200 millimeters. You will find this unit weighs approximately 5.8 kilograms. Therefore, installation requires four sturdy mounting bolts on a panel. One backplane connector accepts up to 16 I/O modules.

Physical Layout and Connectors

The front panel features 16 module slots with individual guide rails. Each slot includes a 48-pin backplane connector for card interfacing. A power supply slot resides at the leftmost position. One grounding stud connects the chassis to plant earth ground. Four mounting holes align with standard 19-inch rack patterns.

Internal Design and Energy Storage

The ASH827209 contains exactly 256 discrete components on the backplane. A 4700 microfarad capacitor bank filters the main 5V DC power bus. This bank reduces voltage ripple for all connected modules. Multilayer PCB traces maintain consistent impedance across all 16 slots. The backplane includes separate ground planes for analog and digital signals. LED indicators show power status for each voltage rail.

Operational Performance

This PLC rack accepts up to 16 I/O modules in a single chassis. It distributes 5V and 24V power to every occupied slot. Moreover, the rack handles high-speed communication between modules via the backplane bus. You can install analog, digital, and specialty cards in any slot order. The unit includes keying features to prevent incorrect module insertion. Four mounting points secure the rack inside a standard cabinet. Consequently, you achieve flexible system configuration for large automation projects. Schneider designed this rack for AS series PLC platforms. Its steel construction provides excellent mechanical rigidity.

In summary, the ASH827209 delivers reliable chassis backplane functionality. Use this rack for factory automation or process control systems. It supports up to 16 modules for extensive I/O capacity. Order this PLC rack for your Schneider system expansion.
