The K8055 interface board has 5 digital input channels and 8 digital output channels. It also features 2 additional analogue inputs and 2 analogue outputs with an 8-bit resolution. The number of inputs and outputs can be increased further by connecting (up to a maximum of 4) cards to the PC USB ports. All communication programs are contained in a Dynamic Link Library (DLL). You can write custom Windows (98SE, 2000, ME, XP) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows auxiliary application tool that supports DLL. DIAGNOSTIC/TEST SOFTWARE: - Separate input/output test - Clear all/set all function - Counter function on input 1 and 2 with adjustable debounce (max. 2 kHz depending on total I/O load) - Analogue output with slide controls - Bar graph (analogue input) - Minimum system requirements: - Pentium-class CPU - USB 1.0 or higher - Windows 98SE or higher (excluding Win NT) - CD-ROM drive and mouse - 5 digital inputs (0= ground, 1= open) (test buttons on board) - 2 analogue inputs with attenuation and amplification options (+5 V provided for internal test) - 8 digital output switches with open collector (max. 50 V/100 mA) (LED indicator on the board) - 2 analogue outputs: - 0 to 5 V, output impedance 1K5 - PWM 0 to 100% open collector output up to 100 mA/40 V (LED indicator on board) - General conversion time: 20 ms per command - Power supply via USB: approximately 70 mA - Dimensions: 145 x 88 x 20 mm https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2017-08-05 https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2018-01-25 https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2018-12-16 https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2021-06-03 https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2021-06-21 https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2022-05-30 https://elecena.pl/product/9689324/wsi8055n-kit-usb-experiment-interface-board 2022-10-27
