Acces I/O Products PICO-II8IDO4A multifunction module

PICO-II8IDO4A from Acces I/O Products is designed for expansion on Pico-ITXe single board computers. This dense, multifunction product features eight individually optically isolated inputs, four fully protected solid-state FET outputs capable of switching up to 3 A each and two 16-bit analog inputs.

The isolated digital inputs are polarity insensitive and accept up to 31 VDC or AC RMS. In addition, jumper-selectable filtering per input channel reduces high-frequency AC and voltage transients. The analog inputs accept unipolar 0-5 V signals and can sustain up to 4 kSps.

The module is suitable for use in space-limited applications. Bus and power connections are built on the stackable unified module interconnect technology (SUMITT) connector, that allows simple connection of PCI Express, LPC, SPI and USB 2.0 buses.

The connector allows up to four Pico-I/O modules to be stacked on a single Pico-ITXe processor board.

It is a high-speed USB 2.0 device that uses a custom-designed driver optimised for a maximum data throughput that is 50-100 times faster than the USB human interface device (HID) driver.

The optical isolation makes the module suitable for use in control and instrumentation applications where high-voltage protection is required.

With appropriate sensors, the two 16-bit analog inputs provided allow the monitoring of a variety of system parameters such as voltage, temperature and humidity.
