I wish the video in Arabic would be much easier

Thanks

so for 4-20 mA we can use a zenner barier and for discrete signals we can use isolated barier? Thank you!

On minutes 5:00 when photo-eye ON it will turn on a diode Where is the power from? Is there any battery inside photo-eye?

Clear, simple and straightforward basic explanation of the main aspects and concepts of intrinsic safety Congratulations! brJust a small conceptual comment: Both "classified" and "unclassified" areas need to be considered and deemed as "SAFE" brElectrical, automation and instrumentation installations, in both cases, need to use equipment with appropriate "Ex" protection types (in classified areas) or associated equipment (in non-classified areas), in addition to performing the applicable installation, inspection and maintenance "Ex" service procedures, according to IEC 60079-14 and IEC 60079-17 👍 brThus, it is suggested to use the term "UNCLASSIFIED AREA" or "NON HAZARDOUS AREA" instead of "SAFE AREA"

What happens if the field instrument is not ATEX certified?

Hello, the video was really helpful in understanding intrinsic safety in a context of plc control system But, I have something to clarify It was said in the video that Div 1 is for environment where combustible dust is present during abnormal conditions I think abnormal is for Div 2 Would like if you can give clarification on this Thank you

4:29 Division 2 means particles present during ABNORMAL operations

Absolute brilliance! Teaching this to new apprentices and time and time again I find exactly what I am teaching right here at RealPars - Thank you

What about intrinsic safety for wireless loops? Does the receiver has to comply with IS regulations too?
Comment from : Jesus Manuel Levinson Rondon

Definitely for Electrical control engineering and technicians

Realpars, please what's the difference between this video vis-a-vis IS vs Non-IS cables?

Highly recommended videos 🔥

i always isolate the inputs and outputs between the panel and the field
Comment from : Adham ShoraFa

Whats the difference between Ex d and Ex i? What are the applications?brbrAlso all barriers will need a photo eye?

You mentioned at the start, that the video would show how to DESIGN a circuit which is intrinsically safe? Is this video demonstrating the LOOP concept (follow the manufacturer certification exactly) and ignores the ENTITY circuit calculations?brWhat about the requirements for the circuit calculation, the entity parameters, cable capacitance and inductance? The number of times I’ve had near misses from sub contractors, mistakenly thinking, that when they pick a barrier which will power a device in the field also means it’s safe for the hazardous area is beyond frustrating (at times has lead to follow up action with their employer when competency is an issue) Also, would it not have been easier just to say the barrier must be installed in a safe area rather than give a specific example of a purged panel which achieves this?

Thank you Realpars You are doing great!

For your example division two actually refers to the presence of a hazardous atmosphere under abnormal operating conditions such as maintenance

another interesting video thanks real pars

Another interesting video on safety Is Siemens ET 200iSP better to use in the field as DP compared with the inc safety barriers?
