* The OMB-DAQ-54 does not have frequency, digital I/O or expansion capabilty.

The OMB-DAQ-54, OMB-DAQ-55 and OMB-DAQ-56 Personal Daqs are full-featured data acquisition products that utilize the Universal Serial Bus (USB), which is built into almost every new PC. Designed for high accuracy and resolution, the 22-bit OMB-DAQ-54/55/56 data acquisition systems directly measure multiple channels of voltage, thermocouple, pulse, frequency, and digital I/O (the OMB-DAQ-54 does not have digital, frequency I/O). A single cable to the PC provides high-speed communication and power to the OMB-DAQ-54/55/56. No additional batteries or power supplies are required, except when using bus-powered hubs.

The OMB-DAQ-54/55/56 modules are the first products in a new family of low-cost, USB-based products from OMEGA. Because of the strict power limitations of the USB, the modules incorporate special powermanagement circuitry to ensure adherence to USB specifications.

The OMB-DAQ-54/55/56 avoid many of the limitations of PC-Card (PCMCIA) data acquisition devices and offer advantages over many PC plug-in data acquisition boards as well.

The OMB-DAQ-54 data acquisition system offers 10 single-ended or 5 differential analog (up to ±20 V full scale) or thermocouple input channels with 16 programmable ranges and 500 V optical isolation.

The OMB-DAQ-55 offers 10 single-ended or 5 differential analog (up to ±20 V full scale) or thermocouple input channels,16 programmable ranges, 500 V optical isolation, 8 digital I/O lines, and 2 frequency/ pulse/ duty-cycle channels.

The OMB-DAQ-56 offers twice the I/O capacity as the OMB-DAQ-55 in the same size package.

To simplify attachment of signals and transducers, the OMB-DAQ-54/55/56 modules feature convenient, removable screw-terminal input connections.

SOFTWARE
Personal DaqViewTM a graphical data acquisition software, is an easy-to-use yet powerful application is provided with the OMB-DAQ-54, OMB-DAQ-55 and OMB-DAQ-56 at no additional charge. The software allows users to configure a test, and display or record data within minutes, without programming.

Personal DaqView lets the user
Select one of any OMB-DAQ devices connected to the system
Set up, configure and display analog, frequency, counter and digital I/O channels in real time
Easily and quickly configure acquisition parameters such as trigger events, stop events and acquisition scan rates
View real-time analog, frequency, and digital I/O using extensive charting and metering displays
Acquire analog, frequency, and digital I/O channels to disk in real time
AView acquisition status at a glance, including triggered time/date, acquisition progress, as well as acquisition destination file

Real-Time Displays
Personal DaqView allows the creation of real-time displays using built-in display options, including digital, dial meter, bar graph, and strip chart displays. No programming is required — simply point, click, and drag desired display options to create a visual display screen.

The OMB-DAQ-54/55/56 are also shipped with PostView, a postacquisition application that permits you to display acquired data previously saved to a file. Drivers for Visual Basic, Delphi and C++ for Windows XP SP2 and SP3/Vista/7 are also included. In addition, drivers are available for icon-based software packages, such as DASYLab and LabVIEW.

 


Personal DaqView PlusTM
The optional Personal DaqView Plus software provides advanced charting capabilities, including multiple traces per chart, multiple chart groups, and support for up to 100 Personal Daq devices attached to one PC.
Allows display groups to be created for customized viewing
Supports up to 100 Personal Daq devices

Personal DaqViewXLTM
The optional Personal DaqViewXL software allows Personal DaqView or Personal DaqViewXL Plus to execute seamlessly from within Microsoft® Excel’s tool palette. Acquired measurements are inserted directly into an Excel spreadsheet in real time.
Allows formula creation on acquired data
Provides control of acquisition from spreadsheet

Personal DaqViewXL PlusTM
The optional Personal DaqViewXL Plus combines the features of Personal DaqView Plus and Personal DaqViewXL into one package.


Expandable Inputs
The OMB-DAQ-55 and OMB-DAQ-56 are expandable through the use of the OMB-PDQ1 and OMB-PDQ2 expansion modules as shown in the table below. The OMB-DAQ54 does not have any expansion capability.
