Description
Product Overview
The KEBA CU313/B-SI/58626/09 is a central control unit designed for KEBA automation systems used in industrial machine control applications. As part of the KEBA CU300 series controller family, the unit provides the main processing platform for executing PLC programs, coordinating connected I/O modules, and managing machine-level control functions. The KEBA CU313/B-SI/58626/09 is commonly found in specialized automation equipment including robotics, plastics machinery, packaging systems, CNC-related applications, and production machines requiring deterministic control performance.
Built as the primary controller within a KEBA control architecture, the CU313/B-SI/58626/09 manages application logic, communication tasks, and interaction with distributed automation components. The controller works together with KEBA expansion modules, operator interfaces, and field devices to form a complete machine automation solution. The SI designation identifies a specific hardware configuration within the CU313/B family, meaning replacement planning should include verification of the exact ordering code, installed software version, and connected peripheral modules.
The KEBA CU313/B-SI/58626/09 remains relevant in long-service production equipment where machine builders and plant maintenance teams need to preserve an existing control architecture instead of redesigning the entire automation platform. Typical replacement projects involve failed CPU hardware, machine refurbishment, or spare inventory preparation. To be completely transparent, controller replacement requires more than matching the front label; application software, parameter files, communication settings, and hardware revision must align before returning a machine to production.
Product Introduction (Non-Templated)
When a dedicated machine controller reaches the end of its service life, the main challenge is restoring the validated control sequence without changing machine behavior. The KEBA CU313/B-SI/58626/09 provides a replacement CPU platform for compatible KEBA automation systems.
Designed for real-time industrial control, this controller supports machine logic execution, I/O coordination, and communication with KEBA automation components, making it suitable for legacy machine maintenance and controller replacement projects.

Frequently Asked Questions (FAQ)
1. Is the KEBA /B-SI/58626/09 compatible with my existing machine controller system?
Compatibility depends on the complete KEBA hardware and software configuration.
Verify:
- Existing controller model and revision
- KEBA project software version
- Connected I/O modules
- Communication configuration
- Application backup availability
A matching controller number does not always mean the installed application will run immediately.
2. Can I hot-swap this?
No standard hot-swap operation should be assumed for the /B-SI/58626/09.
Typical replacement steps:
- Save the existing KEBA application
- Record controller parameters
- Shut down machine power safely
- Replace the CPU unit
- Restore software and settings
- Test machine sequences
Machine controllers normally require controlled restart procedures.
3. Does the /B-SI/58626/09 support firmware v3.1?
Firmware support depends on the exact controller revision and KEBA software environment.
Check:
- Existing firmware version
- Programming tool version
- Application library compatibility
- Connected expansion hardware
The controller firmware and application software must be considered together.
4. Will I lose my machine logic when replacing the /B-SI/58626/09?
The controller hardware does not automatically contain your original machine program.
Before replacement:
- Upload the current project
- Save configuration files
- Record communication parameters
- Backup machine settings
After installation, reload the application and verify all machine functions.
5. How can I verify a New Surplus KEBA /B-SI/58626/09 is authentic?
Recommended checks:
- Confirm KEBA identification label
- Verify complete ordering code
- Inspect connectors and housing condition
- Check hardware revision markings
- Review available inspection records
For machine controllers, software compatibility is as important as the physical unit condition.
6. Can the /B-SI/58626/09 support a legacy automation upgrade?
Yes, when the existing machine architecture is based on KEBA control hardware.
Common applications:
- Machine controller replacement
- Production line restoration
- Robotics system maintenance
- OEM equipment lifecycle support
The original machine software environment should be preserved whenever possible.
7. What should engineers check before commissioning this controller?
Key verification points:
- Confirm power supply compatibility
- Verify I/O module communication
- Restore correct application software
- Check field device communication
- Test safety functions
- Validate machine sequence operation
These checks reduce commissioning time and help maintain the original machine behavior.
