We have about 50 installed for about 3 years now with no failures. We don't use any with HART yet only 4-20 but have choose to install them just in case there is a future need. 15-20 years is a long time to wait if you need to try and pull some info into a asset management tool. The Instro's are also keen to start using some of the smarts on some of the newer instruments, valve sticktion etc. I've seen a few comments regarding the TA failures, I curious if this is only when used with HART! we haven't seen any on current. The newer versions 8.4.x do have the alarming functions but beware the output is a packed Boolean so HAI, LAI etc don't exist so if your upgrading your graphics will need modified. We opted to just go with a RIN-AIN, AOUT-ROUT combination rather than change our graphics, maybe one day when we have time we might go though and start cleaning out the AIN/AOUTs. The 214 is group isolated but there is a new 214b which channel isolated so it looks like a good competitor to the 204. There also used to be a problem with channels freezing (flat lining) but I haven't heard of anything for a long time and haven't seen it here on site. On the whole I've been happy with them but have thought about having a mixture of 204 and 214 mainly because the 204's qualify for advantage upgrade programs where the 214/215s don't, and I very much doubt we will ever go completely HART.
