Test & Measurement: USB-Based Data-Acquisition Modules Boast High Channel Counts

The DT9813-10V and DT9814-10V are high-channel-count, low-cost data-acquisition modules added to the ECONseries of USB 2.0-based devices. The DT9813-10V offers 16 analog inputs, four digital inputs, and four digital outputs. The DT9814-10V provides 24 analog inputs and no digital I/O. Both supply two analog outputs and one 32-bit counter-timer. Resolution is 12 bits, and throughput rate is 50 ksamples/s. They feature a bipolar input range of ±10 V and a high input impedance. Signal connections are made through the modules' screw terminals. The units plug into any PC's USB port, and the included GO! software creates a PC-based instrument. For more advanced applications, they also come with DTx-EZ for Visual Basic.NET and C#, DT-LV Link for LabView, and other software. The DT9813-10V costs $349, and the DT9814-10V is priced at $399.
