The PCI 16 digital I/O board APCI-1516 has 8 digital inputs, 24 V, and 8 digital outputs, 24 V, 500 mA/channel with filters. The board is especially suited for I/O control, signal switching, PLC coupling, as interface to machines or electromechanical relays, etc. in the harsh industrial environment and thus is equipped with many protective circuits. Drivers for Windows 8/7/Vista/XP and Linux as well as programming samples are included, real-time drivers for Windows and Linux are available on request
