EEx d ia devices

EEx d ia devices

Wanted to bring this up to see everyones thoughts on this.

If you have a device that is EEx ia, why would you need an explosion proof housing to make it EEx d ia? From my standpoint, you would take your PWR/Inputs to an IS barrier to the device. If ia is designed and certified for use in hazardous areas, then you could have it in a standard housing. Is there any reason to add the EEx d?

RE: EEx d ia devices

Some devices have dual cerification, i.e. they can be used in an Ex 'ia' application or an Ex 'd' application. One does not preclude the other.

RE: EEx d ia devices

Some property insurers, industrial concerns, and skittish specifiers require both types of protection, but it is kind of rare. You're right that you could use either unless otherwise required.

Plus, as Scotty says, some devices just come that way for either/or application.

Best to you,

Goober Dave
