If DT80 is to be installed inside an explosion proof box as the system is to be used in a hazardous zone 1 area, do we need to install zener type intrinsically safe barrier like this? http://www.process-controls.com/MTL/mtl_intrinsic_Barriers.html

Have a lot of other users done this? What is the most popular IS barrier brand used for DT80?

Advance thanks.

Good morning Orange,

This is a tricky one. The problem is that just about every industry that requires intrinsically safe barriers have their own requirements and the exact requirements can change between site in the same company.

I would suggest you talk to the end customer and find out their exact needs and specifications they are working with.

Cheers,
Roger
