ADU71 USB to 4-20mA Output Interface
The ADU71 USB to Current Output Interface (Transmitter) is a USB bus powered current loop source for driving 4-20mA or 0-20mA input devices. The ADU71 can also be used with external resistors to provide 1-5VDC, 0-5VDC or 0-10VDC signals for variable frequency drives, valves etc. The ADU71 internally generated 24VDC loop supply eliminates the need for an external loop power supply. This low-cost USB to Current Output Interface is easy to use with VB, VB.NET, Visual C++, C , MATLAB, LABView etc. 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 ADU71 includes a 10' USB cable and is available in a flange mount enclosure with a DIN rail mount option.
