The K&S signal adapter board is an electrical adapter module in the wire welding machine. Its function is to relay signals between the control board and execution components (such as motors, grating rulers, sensors), and to complete voltage conversion and isolation protection. It is not a consumable item and is often burned due to high temperature, static electricity or short circuit. When damaged, it can cause position deviation, axis alarm and other faults. It is one of the core components for troubleshooting circuit problems and is crucial for protecting the expensive main control board.
