The National Instruments VXI-DIO-128 is a 128-channel parallel digital I/O module for the VXIbus. This module can be interfaced with many digital I/O applications including: LEDs; optically isolated, solid-state relays and I/O module mounting racks; centronics-compatible printers and plotters; panel meters; electromechanical relays; instruments and test equipment with BCD readouts and/or controls.

The VXI-DIO-128 uses 8 16-bit programmable peripheral interfaces (PPIs) which can further be divided into 16 8-bit ports. 4 82C55A PPI chips control 64 open-drain output channels and 64 input channels with programmable threshold.

With this module, your VXIbus system can serve as a digital I/O system controller for production testing, laboratory testing, and industrial process monitoring and control.
