The Haitronic HR0214-114A motherboard and board supports MACH3 and other computer software for control via a parallel port. Its 17 ports can connect to drivers through optocouplers to control stepper motors on up to 5 axes.
The USB power supply and peripheral power supply are separate. Peripheral inputs operate at 12–24 V and feature reverse-polarity protection. Signal inputs are optocoupler-isolated and support connections for an emergency stop switch and limit switches. The P17 relay output controls the spindle switch, while the isolated 0–10 V analog voltage output via port P1 can control its speed through a suitable converter. P1 can also be used as a PWM output for a spindle controller with an optocoupler input.
