Images are for illustration purposes only. E&OE Features To enable a computer to communicate with the outside world, it is usually fitted with a keyboard, a display and perhaps a mouse. If however it is to be used in certain control applications, or certain control functions are to be carried out, then an interface is needed. The interface card here excels in its simplicity of use and installation. The card is connected in a very simple way to the printer port (there is no need to open up the computer). Likewise there is no need to install an extra printer port, even if a printer is to be used. This can be connected to the card in the usual manner. Connection to the computer is optically isolated, so that damage to the computer from the card is not possible. The card is controlled in a simple way using Turbo Pascal, QBasic, Visual Basic, Delphi, C++ (to use with MS-DOS, Win3.11, Win95, 98, ME, NT, XP, 2000). These procedures are pre-programmed and are provided along with a number of test and example programs on the diskette supplied. The card itself has 16 optically isolated digital connections, which can be freely chosen as either inputs or outputs (eg. 6 inputs and 10 outputs) according to how they are set up by the user. Furthermore, the card has 9 analogue outputs, of which one is high precision, and 4 analogue inputs. If this capacity is not sufficient for a particular application then up to 4 cards can be connected together (1 master and 3 slaves), such that an enormous potential exists. The card can be used with many of our other kits such as : K6714 16 channel relay card, K8023 10-channel 2-wire remote control.Optically isolated from computer16 optically isolated digital connections9 analogue outputs, of which one is high precision and 4 analogue inputsA simple way of controlling using Turbo Pascal, Turbo C, Qbasic, Visual BasicPrinter bypass connector on boardSimple connection with printer portDigital outputs: Optocoupler, open collector output: 50mA - max. 30VDCDigital inputs:Optocoupler input: 5V/5mA, max. 20V/40mAAnalogue outputs:8 outputs DAC1 to DAC8, resolution: 64 stepsMinimum output voltage: 0.1V at 2mAMaximum output voltage: 11.5V adjustable at 2mAResolution per step from 0.1 to 11.5V: 160mV +/- 90mV1 precision output DA1, resolution: 256 stepsMinimum output voltage: 0VMaximum output voltage: 4.5V adjustable at 0.5mAResolution per step from 0 to 4.5V: 17.5mVAnalogue inputs: 4 analogue inputs AD1 to AD4, resolution: 256 stepsMinimum input voltage: 0VMaximum input voltage: 5VInput impedance: 50MohmResolution: 19.5mVCommunication protocol: I²CbusLED indication for each I/O25 pin D series connector for computer25 pin D series connector for printerSupply Voltage: 230VacPCB dimensions: 237 x 133mm (9.3" x 5.2) Additional Information Group Computer / Interface / Programmers Model K8000 PCB Size 237x133mm Voltage 230VAC
