Model DI-149 - Discontinued (Please consider DI-2108)

The DI-149 is a new product for general-purpose data acquisition applications in a long line of low-cost starter kits from DATAQ Instruments. Suitable for measuring preamplified analog signals, the DI-149 in tandem with the included WinDaq software allows real time data acquisition, playback, and analysis performance equal to or better than other products that cost ten times or more than its low price. Predecessors of this instrument have been sold to thousands of hobbyists and professionals for countless data acquisition applications around the world. The DI-149 continues this legacy with noise-cancelling differential analog inputs that are transient-protected to ±150 VDC or peak AC. This tough and tolerant starter kit is an eight-channel version of the popular DI-145, with some enhanced capability.

The DI-149 offers eight analog inputs and four each discrete (digital) input and output channels. Two of the digital inputs (bits D2 and D3) can be used to measure rate up to 10 kHz and counts up to 16,383. The analog inputs offer a fixed measurement range of ±10 VFS at 10 bits of resolution. Sample rates as slow as 11.44 Hz (0.3052 Hz when using WinDaq software) and as fast as 10 kHz (divided by the number of enabled channels) are supported. Included WinDaq software allows a real time display of any combination of analog, digital, or counter/timer channels, and the ability to stream acquired data to disk in recorder-like fashion. Two digital inputs may be used for remote stop/start and remote event operations using WinDaq software. WinDaq also includes software to review recorded data files, including waveform analysis and data file export to Microsoft Excel and other applications.

The DI-149 is supplied with WinDaq software, which limits total sample throughput to 240 Hz or lower. An unlock code for higher speeds allows the DI-149 to operate at 10 kHz. No throughput restrictions exist at the programming level.
