Compatible Replacement & Equivalent Models
When the original KUKA 00-127-755 is unavailable or end-of-life, the following alternatives may be considered subject to firmware and controller compatibility verification:
- KUKA 00-127-755 VER.3 – Earlier hardware revision; functionally equivalent in most KRC2 applications. Verify firmware version before substitution.
- KUKA 00-127-755 VER.5 – Later revision if available; may offer enhanced diagnostics. Confirm backward compatibility with controller software.
- KUKA ESC Safety Board (KRC4) – For KRC4 platform upgrades; requires controller-level reconfiguration.
- Third-party certified safety boards – Only acceptable if certified to SIL2/PLd and validated by a KUKA-authorized integrator.
⚠ Always validate replacement parts against your specific controller serial number and software version before installation.
Why Choose the Original Model
- OEM Guaranteed Compatibility: Designed and tested exclusively for KUKA controller architectures — zero integration risk.
- Safety Certification Integrity: Maintains the original SIL2/PLd safety rating of the robot cell without re-certification overhead.
- Firmware Alignment: Factory-matched to KUKA KSS (KUKA System Software) versions — no firmware patching required.
- Warranty & Liability: Using OEM parts preserves machine warranty and simplifies liability documentation for safety audits.
- Long-term Support: KUKA spare parts are supported through authorized service channels with traceable documentation.
Typical Applications
- KUKA KR series industrial robot safety circuit maintenance and repair
- Automotive body-in-white welding cell safety system restoration
- Palletizing and material handling robot controller overhaul
- Preventive maintenance programs for high-uptime production lines
- Safety system upgrades in collaborative robot (cobot) integration projects
System Compatibility
| Controller Platform | Compatible | Notes |
|---|---|---|
| KUKA KRC2 (Classic) | ✅ Yes | Primary target platform for VER.4 |
| KUKA KRC2 ed05 | ✅ Yes | Verify KSS version ≥ 5.x |
| KUKA KRC4 | ⚠ Conditional | Requires hardware adapter; consult KUKA service |
| KUKA KRC4 compact | ❌ No | Different safety board architecture |
| KUKA iiwa (LBR) | ❌ No | Collaborative robot platform uses different safety system |
Selection Guide
Use the following decision flow to select the correct safety board for your application:
- Identify your controller model – Check the nameplate inside the KRC cabinet door (e.g., KRC2, KRC2 ed05).
- Record the current board part number – Located on the PCB silkscreen label (e.g., 00-127-755 VER.4).
- Check KSS software version – Navigate to KUKA smartPAD → About → Software version.
- Confirm VER compatibility – VER.4 is recommended for KSS 5.4–5.6. For KSS 8.x (KRC4), a different board family applies.
- Evaluate replacement vs. repair – Board-level repair is possible for some fault codes; full replacement is recommended for safety-critical failures.
- Contact Konmask for sourcing – Provide part number, VER, and controller serial for fastest fulfillment confirmation.

Replacement & Compatibility FAQ
Q: Can I use VER.3 instead of VER.4?
A: In most KRC2 applications, VER.3 and VER.4 are functionally interchangeable, but always verify with KUKA service documentation for your specific KSS version.
Q: Is this board compatible with KRC4?
A: Not directly. KRC4 uses a different safety board architecture. Contact us for the correct KRC4 safety board part number.
Q: Do you provide a warranty?
A: Yes — all parts carry a 90-day functional warranty. Extended warranty options available on request.
Q: Can this board be repaired instead of replaced?
A: Some fault conditions allow board-level repair. Contact our technical team with the fault code for assessment.
Q: What certifications does this board carry?
A: The OEM board is CE marked and compliant with SIL2/PLd safety standards as part of the KUKA robot system certification.
