Barriers

Have your client call me.

If you want to get wiser on this subject, the embedded links here can be your toolbox.

Good luck.

Thank you, (whoever you are) for the GA.

Selecting, installing and using hazardous area electrical equipment cannot be done safely without some training. So stop. Either:

1. hand the job over to someone that knows what to do, or
2. wait until a proper training course has been tackled and completed.
3. There is no third option.

PWSlack, the project has not even started and is still under discussion stage, so the question of selection, installation or usage does not come here. I have 3-4 years of experience in Fieldbus Foundation in the hardware used in cabinets and HMI but not in the field.

This query has nothing to do with me working on it since it is only for information.

If the project will use Foundation Fieldbus then the barriers are a must.

Also if you are using barriers you can use less expensive sealing mechanisms.

Finally if you are an amatuer, please consult professionals, since they are the only ones who will know all the applicable codes, standards and equipment to use, here we are trying to give answers where the supplied information is generally less than complete, so any and all answers have to be confirmed.

Will Fieldbus replace LAN type BUS connections?
