Mach 3 interface board

PLo3857qY3

Fully support control via parallel port, such as MACH3, etc.
USB power supply and external power supply are separate for safety.
External power supply input: 12-24V. Equipped with an anti-reverse connection function.
All input signal will be isolated by optical coupler for further connection with emergency
stop,tool setter, limit, ect for PC safety.
One relay output port for control spindle on/off. The output interface. is P17.
One 0-10V analog voltage output port for control of inverter that has relative analog interface,
and for control of spindle speed. The output interface is P1.
If all 17 interfaces are activated, drivers equipped with optical coupler can be controlled and
5 axis stepper motor can be controlled.
As PWM output, P1 can control spindle speed regulator that is equipped with optical coupler.
Connection with 5V input drivers that has common cathode or anode is supported.
