Measurement Computing's USB-3112 is a USB 2.0 full-speed, high-drive device that is supported under popular Microsoft Windows® operating systems. The USB-3112 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-3112 provides eight channels of analog voltage output, eight digital I/O lines, and one 32-bit event counter.
Each of the voltage outputs of the USB-3112 incorporates high-drive current output capability. The high drive current outputs allow each of the voltage outputs to sink/source up to 40 mA (maximum) of load current.
The USB-3112 has two quad (4-channel) 16-bit digital-to-analog converters (DAC). The voltage output range of each DAC channel can be set independently with software for either bipolar or unipolar. The bipolar range is ±10V, and the unipolar range is 0 to 10V. The outputs may be updated individually or simultaneously.
The USB-3112 is powered by a 5-volt, 2-amp AC power adapter that is shipped with the board. All I/O connections are made to the screw terminals located along each side of the USB-3112.
"With reliability a key concern, we chose a name we could trust and the USB unit was a low-cost item that has proved very effective." Gordon Roxburgh, Volunteer Engineer, Brooklands Museum
"USB output has really made life easier on insutrumentation projects because you can simply swap from one laptop to another with minimal fuss. On this sort of operation that gives us extra confidence." Stephen Kemp, Manager, GBG Structural Services
