The PCI-Express 64 digital I/O board APCIe-1564 has 64 digital inputs/outputs, 24 V. It is especially suited for applications like signal switching, ON/OFF monitoring of motors, lights etc., as interface to electromechanical relays, for automated test devices or as interface to machines in the harsh industrial environment. Drivers for Windows 8/7/Vista/XP and Linux as well as programming samples are included.
