Velleman K8000 PC Interface Board Kit

€74,80
Availability: Out of stock

Connection to the computer is galvanically 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 galvanically 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 Velleman kits such as : K6714 16 channel relay card, K8023 10-channel 2-wire remote control.
