Relay Card Kit

Connecting a number of relays to the outputs of an electronic circuit may seem very simple, but in reality it might possibly create some problems regarding the cabling. This kit provides an attractive and compact alternative. Moreover, it can be assembled and connected very rapidly.
Dimensions: 76 x 69mm (PCB)
Power Supply: 9Vdc / 300mA

Quad Triac Switch Card Kit

Relays are usually used to switch AC voltages by means of an electronic control because of their simplicity. However, when switching occurs too frequently or too quickly the life time of the contact points is shortened considerably. This can be solved perfectly by replacing the relays with a triac. Using opto-couplers, the entire interface network remains electrically isolated from the voltage that has to be switched.

PC Interface Board Kit

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.

Stepper Motor Card Kit

For bi- and unipolar motors (maximum 1A). Easy to connect with K8000. High precision possible (up to 0.9┬░, or even more when using a motor with reduction). While the motor turns you can simultaneously check the status of switches using K8000, or drive another motor. You can always give an emergency stop signal. Test program included. Manual test buttons to test the card without K8000 interface. Can be used in every application where positioning is needed (for example a plotter, printer). High precision motor included (12V).
Dimensions: 100 x 90mm (PCB)
Power Supply: 7-25V dc or ac / 1.5A

Programmable Message Board with LCD, Serial Interface and 8 Inputs Kit

Add an LCD display to any low-tech application and make it look high-tech ! Replace up to 9 indicators or lamps by one single backlit LCD, recall messages simply by pressing a button, inputs accept dry contacts, open collectors and logic levels. No programming skills required ! Store up to 9 sixteen-character messages in non-volatile EEPROM memory. 4 operating modes: 1): display the status of all inputs simultaneously 2): display all active inputs 3): display active input with highest priority 4): display text messages in a 'tickertape'-fashion. A default message can be displayed to signal that no inputs are active messages can be transferred to the K8045 from any PC or terminal. Wireless data transfer between PC/terminal and K8045 is possible with optional RX/TX433 modules. 1 on-board push button is available for an application of your choice.

USB Experiment Interface Board Kit K8055N

New Lower Price

The K8055N 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 (XP, Vista, Windows7) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL. Source code examples for Visual Basic, Visual C++, Visual C#, Excel, Delphi and Borland C++ builder are available.
