GE A03B-0807-C001 – 10-Slot Base Unit for CNC Rack Systems

This base unit provides mechanical support and electrical backplane for CNC modules. It holds up to ten separate cards in a single rack assembly. You can mount this chassis inside a control cabinet for CNC or PLC applications.

Key Technical Specifications

Physical Construction and Dimensions

This base unit measures 410 mm in width and 260 mm in height. Its depth reaches 120 mm for deep cabinet installations. The unit weighs 3.2 kilograms, indicating a robust steel frame construction. Four M6 threaded holes accept mounting bolts for secure panel attachment.

Internal Backplane and Energy Storage

Forty-two passive components reside on the internal backplane PCB. Two 4700 µF bulk capacitors provide a total energy storage of 9400 µF. This large capacitor bank decouples the power rails for all ten slots. Consequently, each module receives stable 5V, 12V, and 24V DC simultaneously. The backplane uses separate ground planes to minimize digital noise coupling.

Slot Configuration and Card Guidance

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

Power Distribution and Thermal Management

The base unit distributes power from a single external supply to all slots. Heavy copper traces carry up to 10 amps on the 5V rail safely. Passive convection cooling handles heat dissipation without any moving parts. Therefore, you get reliable operation in dusty or corrosive environments. An earth ground stud connects the chassis to plant safety ground.
