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 Series modules ship with an impressive array of software, including 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 2010 or later) and InstaCalTM installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows® VISTA/7/8/10 (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 on the PDF.

What is the difference between your OMB-AI-EXP32 and your OMB-DAQ-2416 ?  (Besides the price)

Asked by: marklindsayphysics
Hello The OMB-AI-EXP32 is the expansion module for the OMB-DAQ-2416, allowing more channels to be added to the device
Answered by: JA Engineer
Date published: 2019-07-24

Am i able to use single ended and differential channels at the same time when recording data?

Asked by: Unknown
The OMB-DAQ-2416 series cannot do what you are asking for. If a channel is set to differential then the others by default will set to differential, is single ended then all the channels will be set to single ended. Thank you.
Answered by: Application Engineer
Date published: 2019-07-15

Does it support all types of thermocouples?

Asked by: unknown
This device is compatible with J, K, T, E, R, S, B and N thermocouple input types. Thank you for your question.
Answered by: Application Engineer
Date published: 2019-07-01

1. Does it supply power for sensors connected to it, such as LVDT, strain gages. Is this parameter "Supply Voltage ±30V (power on)"? 2. Is it possible to get a connection scheme and description of each port?

Asked by: Anonymous
The OMB-AI-EXP32 is an expansion module with capability of supplying 5 volts DC power supply but can drive only 10 mA. We do not recommend this unit if you are using multiple transducers and load cells. Most transducers need 9-24 volts DC with at least 10 mA current draw. OMB-AI-EXP32, EXPANSION MODULE, User Output Voltage: +5 V, 10 mA max available (pin 19). If you have multiple voltage output devices that you want to connect to a single readout, then please use the INET600 and the INET510 device in conjunction. You will still need an external power supply. If you have more questions please connect us to advise further on the parts you have and want to connect to a readout, we will help you select a DAQ system.
