DIO-0808LY-USB Digital I/O USB I/O unit

Shipping calculated at checkout.

    This USB 2.0-compatible digital I/O terminal can be connected to a USB interface of a PC to provide input and output digital signals (12 - 24 VDC) easily. It allows input for up to eight channels as well as eight output channels. This unit does not require external power supply and it is compatible with USB1.1/USB2.0 for high speed transfers.

    The USB (PC) is isolated from the input and output interfaces by opto-couplers. Therefore, this unit has excellent noise performance. In addition, the terminal connector (with screws) enables easy wiring.

    The driver library [API-USBP(WDM)] allows you to create Windows application software for this terminal in your favorite programming language supporting Win32 API functions, such as Visual Basic or Visual C++.
