Velleman VM140 Manual De Instrucciones página 3

This computer interface board has a total of 33 inputs / outputs, including analogue / digital and a
PWM output.
The connection to the computer via the USB port is galvanically-optically isolated, so that damage to
the computer is impossible 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 Borland Delphi, Borland C++ Builder, Microsoft
Visual Basic, Microsoft VC or most other 32-bit Windows application development tool that supports
calls to a DLL.
