hWexla is a switch motor designed in Model Railroader Club Brno I to switch their turnouts. The project is opensource & openhardware, this repository contains all data.
- Model 9g servo used as a drive force.
- Magnetic detection of movement. No mechanical parts detecting servo movement.
- Installation via unified D-SUB 25 connector.
- 2 inputs for position setting.
- 2 outputs for position indication (up to 200 mA).
- 2 IO pins for debug/panel.
- 2×3 relay for switching track current (up to 3 A).
- Diagnostic interface.
- IO protection.
- Slave mode.
- Input voltage: 10–20 V.
- Stabilizing of servo-voltage is solved in external board – hWexla contains only connector. Stepdowns like RB0005 are expected to be used.
