Compatible Replacement & Equivalent Models
When the original K.3784.05 is unavailable or discontinued, the following models are commonly evaluated as functional replacements. Always verify electrical and firmware compatibility before substitution.
- Rofin LasCon-WaC-1 — Earlier revision; same I/O architecture, verify firmware version
- Rofin LasCon-WaC-3 — Later revision with extended I/O; backward-compatible in most configurations
- Rofin SLOMO-2 / SLOMO-3 Interface Boards — Alternative I/O boards used in select DC-series laser heads
- Third-party CNC I/O Expansion Modules — Suitable for system integrators rebuilding control architecture; requires custom wiring and parameter mapping
Note: Konmask.com can assist with cross-reference verification. Contact us with your laser model and serial number for a confirmed match.

- Laser power modulation and beam-on/off signal interfacing
- Industrial laser maintenance and field service repair
- OEM machine builder integration for Rofin laser sources
System Compatibility
- Rofin DC Series (DC010 – DC050) CO₂ laser sources
- Rofin CW Series fiber and diode laser modules
- Rofin StarCut / StarWeld laser systems
- External CNC controllers via analog ±10 V / digital 24 V I/O (verify pinout with your system documentation)
Compatibility is subject to firmware revision. Please provide your laser serial number when ordering to confirm fit.
Selection Guide
Use the following criteria to select the correct interface module for your application:
- Step 1 — Identify your laser model and serial number from the laser source nameplate.
- Step 2 — Confirm the part number on the existing board (K.3784.05 or adjacent revision).
- Step 3 — Check I/O channel count required by your CNC controller (analog outputs, digital I/O lines).
- Step 4 — Verify firmware version compatibility if substituting with LasCon-WaC-1 or WaC-3.
- Step 5 — Contact Konmask.com with your findings for a confirmed part recommendation and lead-time quote.
