Interworld Electronics has released a new USB-104 form factor Digital I/O module from Acces I/O. The USB-DIO-32I provides 32 lines of independently selectable buffered digital I/O. The USB-DIO-32I features on-board intelligent firmware that provides Watchdog Timer, Configurable Power-On Defaults, Contact Debouncing and Latching, Digital Pulse generation and Matrix Mapping functionality. The USB-DIO-32I is a USB 2.0 high-speed device and is compatible with both USB 1.1 and USB 3.0 computer ports.

All I/O lines are buffered by tri-state buffer transceivers capable of sinking 64 mA or sourcing 32 mA. The buffers are configured under program control for input or output. 10K ohm pull-ups (to +5 VDC) on the board allow for contact monitoring and ensure a known signal level at power-up.

Power is supplied to the cards via the USB cable. If high source current capabilities are required, an external power option may be used. The I/O wiring connections is via an industry standard 50-pin connector. For external circuits, fused +5VDC power is available at the connector. This resettable fuse is rated at 0.5A.

The USB-DIO-32I is supplied in a rugged industrial case. An OEM (board only) option is also available. What makes the OEM option unique is that its PCB size and pre-drilled mounting holes match the PC/104 form factor. This allows the modules to be added to any PC/104, PCI-104, or PCI/104-Express stack making them perfect for embedded applications.
