GE A05B-2316-C111 – 5-Slot Backplane Rack for CNC Systems

This backplane rack provides mechanical support and electrical interconnect for five CNC modules. It distributes power and data signals across all installed cards. You can mount this chassis inside a standard 19-inch control cabinet.

Key Technical Specifications

Physical Construction and Dimensions

This backplane rack measures 280 mm in width and 200 mm in height. Its depth reaches 85 mm for shallow cabinet mounting. The unit weighs 1.4 kilograms due to the steel chassis construction. Four M5 threaded holes accept bolts for secure backplate attachment.

Internal Backplane and Energy Storage

Twenty-eight passive components reside on the internal backplane PCB. Two 2200 µF bulk capacitors provide a total energy storage of 4400 µF. This capacitor bank decouples all three power rails for the five slots. Consequently, each module receives clean 5V, 12V, and 24V DC simultaneously. Heavy copper traces carry up to 5 amps on the 5V rail safely.

Slot Configuration and Card Guidance

Each of the five slots features a 32-pin backplane connector for module interface. Plastic card guides align each board perfectly before connector engagement. You can install CPU, I/O, or motion modules in any combination of slots. Therefore, the system allows flexible configuration based on your application needs. A top retaining bar secures all modules against vibration in mobile equipment.

Power Distribution and Cabinet Mounting

The backplane distributes power from a single external supply to all slots. Separate ground planes minimize digital noise coupling between adjacent cards. Passive convection cooling handles heat dissipation without fans or moving parts. An earth ground stud connects the chassis to the plant safety ground. You can mount the rack vertically or horizontally without performance changes.
