Failure probability is categorized like this (in order of most likely to least likely.
Mechanical
Electro-Mechanical
High Current
Low Current
Solid State
As you eluded to, environment can be an exception to the general rule.
(Relay card most likely, and MTBF is useless unless solid state, as...

Next time (and anyone else seeing their design requires 5-10 counter/rate meters in a single panel door), use a HMI screen instead like Allen Bradley's Panelview. Then you will be only cutting out one squire to mount HMI screen, and you get the added functionality and expandability at little cost.
