ADU100 USB Data Acquisition Interface  ( Dimensions, 5.1" X 2.8  X 1.0" )

The ADU100 features 3, ISOLATED 16-bit  analog inputs, 4 digital I/O lines, one 5 AMP relay contact output, four 16 bit event counters, and an auxiliary RS232 port. Two of the analog input lines can be programmed in 20mV to +/-2.5V ranges via an internal PGA. The third analog input is a high-level input with programmable ranges of 0-5, +/-5, 0-10, and +/-10 VDC.  Two reference outputs are available ( 2.5000V and 5.00V ) to allow direct connection of strain gauge type sensors. This low-cost data acquisition  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 ADU100 USB data acquisition interface also features an auxillary RS232 port for connecting Legacy RS232 devices. ( ADR Products ) The ADU100 includes a 10' USB cable and is available as a PCB or in an enclosure with several mounting options.The variety of I/O on this product make it unique and well suited for integration into a variety of instruments.
