With a CNC Breakoutboard you can controll a CNC system through a LPT port of a computer. One cnc-breakoutboard can for example controll 4 relais, 5 switches and 4 stepper or servomotors. Any other combination is of course also posible, like 6 steppermotors and 5 switches at the same time.

This breakoutboard has 4 relais with goldplated contacts and replacable amplifiers in the form of 3 pcs 74HCT573 drivers. Those can be repaced ( if needed ) by other types to match logic levels. The board can be configured to wait for a few seconds after powerup before being active, or wait until a chargepump signal ( mach3 ) is detected on pin 1 of the LPT input. In the latter case, the relais connected to pin 1 is not able to switch anymore. Furthermore external solidstate relais can be connected to an aditional connector, to switch even higher loads.
