This type of the CNC USB MACH3 Controller Card is of strong anti-interference ability, the frequency converter interface is isolated from the computer and the main control circuit,. The interference signal will not be introduced because of the introduction of the external strong current equipment.
The interface output 0-10V analog signal also can be configured as a 0-5V output, convenient for you to choose the type you need.
To make the system more stable, you can use an external 24V DC power supply to isolate USB and external ports.
