ADU200 USB Relay I/O Interface ( Dimensions, 5.1" X 2.8  X 1.0" )

The ADU200 USB  Relay I/O Interface Controller allows control of 4 relay contact outputs, 4 contact or TTL inputs, and 4 event counters via a USB port.  The ADU200 can effectively convert  a standard PC to a powerful   PLC ( programmable logic controller ). High quality PA-Series relays from Aromat offer superior performance. This low-cost serial relay contact  interface is easy to use with VB, and Visual C++ via standard HID drivers included with Windows 98,2000,XP.  A mini-driver ( DLL )* is also provided allowing control using standard ASCII commands using familiar readfile , writefile commands. The ADU200 USB interface also features an auxillary RS232 port for connecting Legacy RS232 devices. ( ADR Products ) The ADU200 includes a 10' USB cable and is available as a PCB or in an enclosure with several mounting options.
