This board is a PCI bus-compliant interface board for input/output of digital signals. This board can output and input the digital signal of 12 - 24VDC. PIO-64/64L(PCI)H can input and output up to 64 channels. With the Windows version, the Linux version driver (API-PAC(W32)).

Common power-supply configuration in 16 channel units, capable of supporting different external power supplies
A different external power supply can be used for each common pin as it is shared by 16 channels.

Optocoupler used to electrically isolated I/O signal interface from the PCI bus, offering good noise immunity
Opto-coupler used to electrically isolated I/O signal interface from the PCI bus, offering good noise immunity.

Capable of using up to 16 channels of input signals as interrupt inputs
Capable of using up to 16 channels of input signals as interrupt inputs. Also capable of selecting the input signal edge for generating interrupts.

Digital filtering that prevents input signal noise and chattering
