  • This USB board was designed to be used in today’s new Kiosk designs as a highly functional and compact I/O module. It is also an ideal solution for adding portable, easy-to-install digital I/O capabilities and solid state FET outputs to any computer with a USB port. It is a high-speed USB 2.0 device, USB 3.0 and 1.1 compatible. The unit is plug-and-play allowing quick connect/disconnect whenever you need additional I/O on your USB port.

    The board features 48 channels of TTL-compatible digital I/O with high output current capabilities. Each digital port can be programmed to accept inputs or to drive outputs. Power is supplied to the card via the USB cable, or, for higher source current capabilities, an external power option may be ordered. All I/O lines are buffered by a type 74ABT543A tristate buffer transceiver capable of sourcing 32mA or sinking 64mA. Jumper selected resistors permit configuration of each 8-bit I/O group for pull-up (to +5 VDC), pull-down (to ground) or floating depending on the application requirement. Pull-ups are useful for contact monitoring, while pull-downs assure that there are no erroneous outputs at power-up until the card is initialized by system software.

    The board also features 24 high side power MOSFET switch outputs. The fully protected outputs are de-energized at power-up to prevent an unintended control signal until turned on via software command. Each output shares a common switched voltage of 5-34VDC at up to 2A. Data to the solid state outputs are latched.
