ADU100

USB Data acquisition interface
ISOLATED - 16-bit with PGA and relay output

Description

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. 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.
