The Yocto-IO-V2 device provides 4 digital I/O, electrically isolated from the USB bus. Each I/O bit can be configured individually as a simple input, an open-drain input (internal pull-up), a TTL/CMOS-like output, or an open-drain output (open collector).
Without external power source, each I/O pin can receive or produce a digital signal at 3V or 5V levels (low current).
With an external power source, the device can work with voltages up to 30V and deliver up to 500mA per channel, which makes it possible to work with industrial I/O systems.
If you need more channels, you can use the Yocto-Maxi-IO-V2.
USB cables and enclosures to be ordered separately.
