Adequate but fragile
Basic device does provide USB connection to computer. Software is basic and cumbersome. The device is not robust, recommend unplugging power and USB when not in use.

OM-DAQ-USB-2400 - Beware when using w/ TCs
I purchased four of these units (over time) for use with various thermal experiments involving building assemblies (temperature ranged from 0 to 100F). With 8 differential channels on each unit, this model seemed like a bargain and I've always looked to Omega for easy online shopping and competitive prices.
When I started pairing these units together, I noticed pretty significant disagreements between TC readings when calibrating multiple devices at once. This disagreement wasn't resolved with offsets and scaling. I thought my devices needed calibrated, but digging deeper in the specs, I found the combined TC and cold junction compensation error for these units are +/-4F...not good for measurements requiring minimal absolute error, and worse than some of my old Omega handheld loggers. It would have been nice for the specs to provide the total measurement error, with CJC and TC errors together, as other products usually list them.
Using this model for analog voltage signal logging has worked well, on the other hand, and the software is simple and easy to use.
I'm upgrading to a DAQ-2416 to get better accuracy and I hope I can get more out of this unit even though the $$ per TC channel isn't that different from the USB-2400.

Did not live up to expectations.
The OM-DAQ-USB-2401 was acquired for the purpose of running 5 to 8 load cells. It was recommended specifically for the job, by an Omega support engineer on the phone support line.
When received, we found that the label on the top, identifying the ports, was 180 degrees off. We also found that the unit is very restricted with regards to excitation current! It is only capable of feeding 2 load cells, not 8.
Very disappointing.

Calibration issues
Calibration Cert not offered but when we tried to calibrate the unit as required for our use, it failed. Had to return the unit for Omega to review because they said it was factory calibrated. If that's the case, then why would a cert not be offered? Frustrating.

device works but software is limited
For my job, I need to connect this device to others in my network, and we only use Linux Systems. Is there some way to config the data acquisition module using standard serial communication?
I did make a program with python that can read serial port, but I not have any response.
Greetings.

Not recommended
It stopped working after 1-year use, error while setting data scanning rate. Doesn't support USB.

Caution: Input volt/current spike can damage 2401
The unit is easily damaged if there is a voltage/current spike, this renders the 2401 device useless. This has happened on three of 4 Omega units. Easy to use, but unprotected.
Ex: A suspected voltage spike occurred during DAQ, the unit(s) then began showing erratic thermocouple readings. We restarted all devices and found that the Omega 2401 would not "Configure."
