Velleman K8061 Extended USB Interface Board Kit

Availability: Out of stock

This interface board has a total of 33 input/outputs: including analogue / digital and + 1PWM output.

Connection to the computer is galvanically-optically isolated, so that damage to the computer is not possible thus providing a high level of secure implementation.

All communication routines are contained in a Dynamic Link Library (DLL).
You may write custom Windows*. Applications in Delphi, Visual Basic, C++ Builder or most other 32-bit Windows application development tool that supports calls to a DLL.
