KEBA Kemro k2-700 OB781/D – High-Performance CNC Control Module | Kemro K2-700 Series
Engineering Background
The KEBA Kemro K2-700 platform is an advanced CNC control architecture developed by KEBA AG (Austria), engineered for demanding multi-axis machining centers, turning centers, and flexible manufacturing systems. The OB781/D module serves as a core operator/bus interface board within the K2-700 control cabinet, providing deterministic real-time communication between the HMI layer and the drive/I/O subsystems.
Product Positioning
Designed for OEM machine builders and end-users requiring a direct replacement or spare for KEBA Kemro K2-700 series CNC systems. The k2-700 OB781/D is a precision-engineered board-level component that maintains full compatibility with the Kemro K2-700 hardware ecosystem, minimizing downtime and re-engineering costs.

System Architecture & Signal Flow
Within the Kemro K2-700 control cabinet, the OB781/D module occupies the operator/bus interface slot. It bridges the operator panel (HMI) signals and the internal K2-700 backplane bus, routing operator commands (cycle start, feed hold, axis jog, spindle override) to the real-time CNC kernel. The /D variant designation indicates a specific hardware revision with updated bus arbitration logic for improved noise immunity in high-EMI machine environments.
Signal flow: Operator Panel → OB781/D Interface → K2-700 Backplane Bus → CNC Kernel → Drive Amplifiers → Servo/Spindle Motors

Technical FAQ
Q: Is the OB781/D compatible with all K2-700 cabinet revisions?
A: The OB781/D is designed for the Kemro K2-700 platform. Compatibility with specific cabinet revisions should be confirmed against your cabinet’s BOM or by contacting our technical team with your cabinet serial number.
Q: Can this module be used with the Kemro K2-500 or K2-1000 series?
A: No. The OB781/D is specific to the K2-700 platform architecture. Cross-platform use is not supported.
Q: Do you provide a warranty?
A: Yes. A 12-month warranty against manufacturing defects is provided on new units. Refurbished units carry a 6-month warranty. Terms available on request.
Q: What is the typical lead time for international orders?
A: Standard international shipping (DHL/FedEx) typically delivers within 5–10 business days after dispatch. Express options available.
Q: Can you provide ECCN / export classification?
A: Export classification documentation is available upon request for customers requiring customs pre-clearance.
