Personal DAQ/55

22-bit USB data acquisition module

Personal DAQ/55


Please consider our newer 24-bit voltage and temperature measurement devices 

Designed for high accuracy and resolution, these IOTech 22-bit Personal data acquisition systems from Firetail DAQ directly measure multiple channels of voltage, thermocouples, pulse, frequency, and digital I/O*. A single cable to the PC provides high-speed communication and power to the Personal Daq. No additional batteries or power supplies are required in most applications**.

The Personal Daqs are supplied with Personal DaqView, IOtech’s Windows®-based data logging application that allows you to set up your acquisition applications and save acquired data directly to disk. The Personal Daqs also include PostView, a post acquisition application that permits you to display acquired data previously saved to a file. Drivers for Visual Basic® and C/C++ are also included. In addition, drivers are available for icon-based software packages, such as DASYLab® and NI LabVIEW™.

Both the Personal Daq/55 and the Personal Daq/56 can be easily expanded with one of two available PDQ snap-on expansion modules, bringing the total capacity up to 60 analog or thermocouple channels, 32 digital I/O lines, and 4 frequency input channels. Furthermore, USB hubs can be used to create multi-unit systems.

* The Personal Daq/54 does not have frequency, digital I/O, or expansion capability

** In rare instances an external power source is required when PC-supplied power is inadequate
