Velleman VM140 EXTENDED USB INTERFACE BOARD

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.
