Hi Everyone,
I'm trying to spec an intrinsically safe LED certified for use in a class 1 div 2 environment. I typically use Allen-Bradley 800H LEDs but since these are not certified intrinsically safe, so I can't use them.
In fact, why is it that an LED needs to be "intrinsically safe" anyway? Does a device not have to store energy to require certification? From my understanding, LEDs are a bit "grey" when determining whether they are considered simple devices or not (i.e. do not require IS cert.). Why is this?
I have found a couple different LEDs made by BEKA and RTK that are intrinsically safe, however they are only certified for operation at -20?C.
I require certification for use at -40?C.
Any help would be greatly appreciated!
Thanks!
Derek
