Description
Description
This is a FluidNC CNC Module to electrically isolate remote displays and pendants. Placing a display or pendant at the end of a long cord can make the host controller vulnerable to voltage spikes and ESD common in CNC environments. This also attempts to provide some amount of protection from user wiring and configuration errors.
Features.
- Isolated 12V 3A power supply.
- PTC fuse protection on 12V power supply.
- Digital isolators for Tx and Rx signals.
- TVS diodes to protect circuits from high-voltage surges and static electricity (ESD)
- Series resistors to help protect digital signals from short circuits.
- 2 standard pendant connector types.
Note: This is currently shared for collaboration purposes only. It is not complete or tested.
