Digital I/O

The I/O systems can detect or switch digital states (on/off). The USB-PIO(-OEM) processes standard TTL/CMOS levels (0–5 V) at a very low current. If higher voltages and currents need to be processed, the USB-OI16 or the USB-PIO can be used in conjunction with the OR8. The OI16 optocoupler board is particularly suitable for the internal measurement cards and the LAN measurement systems.
