The OMB-DAQ-2416 and the OMB-DAQ-2416-4AO are highly accurate, multi-function measurement and control modules for the USB bus. These modules are 24-bit analog input devices for voltage or temperature, with eight digital I/O lines and two counters. In addition to the features listed, the OMB-DAQ-2416-4AO also includes four analog output channels with 16-bit resolution, ±10V output range, and an aggregate 1000 Hz update rate.
System Expansion
With the addition of an optional OMB-AI-EXP32 analog input expansion module, the number of analog input channels on the OMB-DAQ-2416 or OMB-DAQ-2416-4AO can be doubled—increasing from 16 differential/32 single-ended inputs, to 32 differential/64 single-ended inputs. The expansion module also provides an additional 16 channels of DIO, bringing the total DIO count of the mated pair to 24.
All features of the OMB-DAQ-2416 series module are included when the OMB-AI-EXP32 is attached, including the ability to accommodate thermocouples on any input channel, built-in cold junction compensation, and open thermocouple detection. The OMB-AI-EXP32 can be plugged directly into a OMB-DAQ-2416 series module. The packaging for the OMB-DAQ-2416 series and the OMB-AI-EXP32 ensures ease of use in a variety of applications. Detachable screw terminals facilitate attaching and removing without re-wiring. The modules can easily be DIN-rail mounted for rack applications.
Software
The OMB-DAQ-2416 modules ship with an impressive array of software, including the new TracerDAQ?, a full-featured, out-of-the-box data logging, viewing, and analysis application. Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft? Visual Studio? programming languages, and other languages, including DASYLab?, and ULx for NI LabVIEW? (comprehensive library of VIs and example programs compatible with 32-bit and 64-bit LabVIEW v8.5 through 2012) and InstaCalTM installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows? XP (32-bit only) and VISTA/7/8 (32-bit and 64-bit) operating systems.
The OMB-DAQ-2416 Series data acquisition modules are supplied with TracerDAQ software which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:
Strip Chart—Log and graph values acquire from analog inputs, digital inputs, temperature inputs and counter inputs
Oscilloscope—Display values acquired from analog inputs
Function Generator—Generate waveforms for analog outputs
Rate Generator—Generate waveforms for counter outputs
TracerDAQ PRO is an enhanced version of TracerDAQ. A comparison of some of the features included in TracerDAQ vs TracerDAQ PRO is shown below.
