While preparing a story on another product's life cycle status, we became aware of the fact that Rockwell had updated the status of their 1797 Flex Ex line to “end of life.”

[flexex-artadrr-ebay]The Flex Ex line of distributed I/O is based on the popular Flex I/O product line, but it's also hazardous area rated in North America for Class I Zones 1 and 2, Groups IIC, IIB, and IIA.

While Rockwell has updated the Flex Ex product line with a discontinued date of 12/31/2016, no word on a replacement Allen-Bradley line of intrinsically safe I/O could be found on their website.

So what do you think? Is Rockwell likely to release a new line of intrinsically safe I/O, and if so when would they announce it?

Or is the market for installing I/O in hazardous locations not large enough to warrant a replacement product?

  1. I would just like to know what kind of failure rate exists on the 1797 Ex Flex I/O in an effort to plan and purchase replacements for all of our current 1797 ex flex I/o

    • Good morning Ken,

      If you contact your local Rockwell representative they can talk to you about MTBF rates for most any of their products.

      Hope this helps,

      Shawn Tierney
