UE9 Datasheet

Original Ethernet/USB multifunction DAQ.

This datasheet covers all UE9 variants:  UE9 and UE9-Pro.

Production Status:  NLA (no longer available as of March 2022).  Many parts required to build the UE9 have been discontinued by their manufacturers. Production of the UE9 has become increasingly difficult and expensive, if not impossible. The T7 is a newer (not drop-in) replacement that is superior in every way including cost.

The UE9 family was the first LabJack product to incorporate industrial strength Ethernet, and offers a wide range of capabilities. It has a long service record of reliability and customer satisfaction, but new applications should consider the newer T7 or T7-Pro instead.

These HTML pages form the complete datasheet, manual, and user's guide for the UE9.  Most information in this datasheet applies to all UE9 variants.  Specifications are in Appendix A.  UD library documentation is in Section 4.

Offline PDF Note

Offline PDF

If you are looking at a PDF, hardcopy, or other downloaded offline version of this document, realize that it is possibly out-of-date since the original is an online document.  Also, this document is designed as online documentation, so the formatting of an offline version might be less than perfect.

To make a PDF of this entire document including all child pages, click "Save as PDF" towards the bottom-right of this page.  Doing so converts these pages to a PDF on-the-fly, using the latest content, and can take 20-30 seconds.  Make sure you have a current browser (we mostly test in Firefox and Chrome) and the current version of Acrobat Reader.  If it is not working for you, rather than a normal click of "Save as PDF" do a right-click and select "Save link as" or similar.  Then wait 20-30 seconds and a dialog box will pop up asking you where to save the PDF.  Then you can open it in the real Acrobat Reader rather than embedded in a browser.

Rather than downloading, though, we encourage you to use this web-based documentation.  Some advantages:

  • We can quickly improve and update content.
  • Click-able links to further or related details throughout the online document.
  • The site search includes this document, the forum, and all other resources at labjack.com.  When you are looking for something try using the site search.
  • For support, try going to the applicable page and post a comment.  When appropriate we can then immediately add/change content on that page to address the question.

Periodically we use the "Save as PDF" feature to export a PDF and attach it to this page (below).


Has there been any MTBF analysis done on any of the labjack products?

We have not done an MTBF specific analysis or testing ourselves.  The UE9 is just made of normal semiconductor components, and nothing with a rating in terms of limited lifetime.  It is rare for a UE9 to fail on its own, and I can't say we have ever seen a failed UE9 where the failure was not most likely attributed to damage due to an external influence.  Overwhelmingly, all failed UE9s we see have damage attributed to an out-of-spec voltage/current that has been introduced to the UE9 from some external source.  That is the nature of a DAQ device like ours that has so many user controlled connections (communication, power, ground, and lots of I/O).


The following mentions a DoD document that might provide a way to come up with an MTBF number based on models, but we have not pursued it:



We do get asked about MTBF occasionally.  Last time, it was someone from MIT that asked, and they later responded to us with:

"Typically, for an electronic device such as yours, with off the shelf components, and with an approximate number of parts-by-count of roughly 50, I should expect an MTBF of 30K~75k hours. I'll probably utilize some figure within that range."

Can a CB37 extension board be used with a UE9?
