AdapterBoard10V-3V3 Analog Signal Converter for PoKeys57CNC, PoKeys57U, PoKeys57E, and Arduino

The AdapterBoard 10V-3V3 is a specialized, ultra-compact analog signal interface designed to bridge the gap between industrial 10V sensors and modern 3.3V logic controllers. By accurately stepping down a 0-10V input signal to a safe 0-3.3V output, this board eliminates the risk of overvoltage damage to sensitive microprocessors while maintaining the linear integrity of your analog data.

Seamless Integration & Technical Performance
Specifically engineered to streamline the connection between the PlasmaDiv and the PoKeys57CNC controller, this board replaces the need for unreliable, hand-built resistor dividers. It features a high-reliability screw terminal input for the 0-10V signal and delivers the processed output through a standardized 10-pin IDC connector. While optimized for the PoKeys family—including the PoKeys57CNC, 57U, and 57E—its universal design makes it an ideal solution for Arduino, ESP32, and other 3.3V-based microcontroller systems. The board operates with a fixed conversion ratio, ensuring that your software receives a precise representation of the original 10V signal for accurate torch height control or sensor monitoring.

Industrial Build & Compact Form Factor
Designed for tight control cabinets where space is at a premium, the AdapterBoard 10V-3V3 features a miniature footprint of approximately 22mm x 37mm. Despite its small size, it is built for the rigors of an industrial environment and is fully compatible with DIN rail adapters for a clean, professional, and vibration-resistant installation. The board’s layout is optimized for low-noise signal transmission, which is critical when converting sensitive analog data in the electrically noisy surroundings of a CNC plasma table or automated workshop.

Kit Contents & Specifications
The system is sold as a complete integration kit to ensure an immediate, "plug-and-play" experience. Each package includes the AdapterBoard 10V-3V3 module along with a 10cm flat ribbon cable terminated with two 10-pin IDC female connectors. This allows for an organized and secure link between the adapter and the controller’s analog input header. The unit supports a full input range of 0-10VDC and provides a proportional 0-3.3VDC output, making it suitable not only for plasma voltage sensing but for any application requiring industrial signal scaling.

Why this Adapter is Essential for Your Build
Directly connecting a 10V signal to a 3.3V input will instantly destroy your motion controller's processor. The AdapterBoard 10V-3V3 provides a factory-calibrated, professional safeguard that ensures your system stays protected. By using this dedicated hardware instead of a "DIY" solution, you gain a cleaner signal, a more professional cabinet appearance, and the peace of mind that your expensive CNC electronics are operating within their safe voltage parameters.
