Images are for illustration purposes only. E&OE Features The K8055 interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows (98SE, 2000, Me, XP) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL.DIAGNOSTIC / TEST SOFTWARE:Separate output / input testClear all / set all functionCounter function on inputs 1 and 2 with adjustable debounce (max 2kHz depends on total I/O load)Analogue output set slidersAnalogue input bar-graph indicationMinimum system requirements:Pentium class CPUUSB1.0 or higher connectionWindows 98SE or higher (Win NT excluded)CD ROM player and mouse5 digital inputs (0= ground, 1= open) (on board test buttons provided)2 analogue inputs with attenuation and amplification option (internal test +5V provided)8 digital open collector output switches (max. 50V/100mA) (on board LED indication)2 analogue outputs: 0 to 5V, output resistance 1K5PWM 0 to 100% open collector outputs max 100mA / 40V (on board LED indication)General conversion time: 20ms per commandPower Supply through USB: approx. 70mADiagnostic software with DLL includedDimensions: 145 x 88 x 20mm (5.7" x 3." x 0.8") Additional Information Group Computer / Interface / Programmers Model K8055 PCB Size 145x88x20mm Current 70mA
