Auch sinking outputs, aber das müsste man ja hinbekommen mit ein bischen Aufmerkstamer Verdrahtung.

For slow I/O for your workpiece exchange you can also use (provided you have a PCI slot or PCIe Slot) one of the cheap parallel port cards and a simple Break out board for the parport?
Or you buy an external PLC (Programmable Logic Controller) if I/O needs to be added anyway. Then you only need the Input to start the PLC and a few outputs to make sure everything is, ready with workpiece change and start new machining cycle.
