Hello everyone, 

I am finding trouble selecting similar modules to S7 1500 1511 PN that are similar to the S7-300 ones.

Can you please guide me with this selection here, I want the same card for S7-1500, is there a similar one to this? and can the 1511 PN configure such card ? Thank you

Ok, I will answer myself here, after searching for 2 hours I have found this link

it seems there are no EX hazard modules for S7-1500 because all the modules are now ex certified, list of modules in the certificate in this link.

Hope this will help someone

Hello Automoto;

It seems you are correct, Siemens has not yet integrated a S7-1500/ET 200MP failsafe analog input module in their catalogs.

See: http://w3.siemens.com/mcms/distributed-io/en/ip20-systems/et-200mp/Pages/signal-modules.aspx?tabcardname=failsafe%20i/o

As a workaround, you could use the same module you were describing earlier, as part of a ET 200M station on Profibus or Profinet, controlled by your S7-1500 F-CPU. You have the choice of using any Profibus/Profinet F-AI module from different platforms, actually. Look at this attachment, taken from the Simatic Safety v13 manual:

Hello,

yes, you can use this one : 6ES7531-7QD00-0AB0

If you need there is another "identical" but capable of handling more inputs (8) , the 6ES7531-7KF00-0AB0

And yes, you can use that card in any 15XX PLCs

 dchartier,

I know that I do ask alot of questions on this forum,

mostly you are the one that answer them, if you hate that I do use the forum to the max you should stop answering me so perfectly, because your full answers, support and the support of people like you is why I come back to use siemens support forums whenever I face any trouble and what keeps this website alive helping thousands around the world.

Thank you so much.

Hello Davinator,

at first i did not want to go with the 4AI  module because it does not cover the description of the S7300 module :

"SIMATIC S7, ANALOG INPUT SM 331, OPTICALLY ISOLATATED, 4 AI, 0/4 - 20MA, 1 X 20 PIN, F. SIGNALS F. HAZARDOUS AREAS, CAPABLE OF DIAGNOST.,PTB-TESTED"

no F.Hazard thing in the S71500 modules, which is the EX type of modules in the s7 300 module range :)

but then found this link:

 https://support.industry.siemens.com/cs/document/89291166/for-use-in-hazardous-locations-iecex-dekra-exam-dmt?dti=0&pnid=19902&lc=en-WW

and it turns out that all S7 1500 modules are EX certified, thats why they stopped mentioning EX or have a different range for it 

Hello Everyone,

I feel this thread has taken a wrong path.

Question is about S7-1500 modules for hazardous applications/areas not about fail safe applications.

As far as I could see, ET200MP/S7-1500 fail safe modules are not suitable for signals in hazardous areas.

it seems there are no EX hazard modules for S7-1500 because all the modules are now ex certified, list of modules in the certificate in this link.

Hope this will help someone

 No, You are wrong.

As far as I can see, none of ET200MP/S7-1500 is certified for Ex ib signals.

So, none of them is equivalent to the6ES7331-7RD00-0AB0.

 wrong once again.

Before I explain, I wish if you provide answers for the below questions.

1- What's your application?

2- Where is your control panel (indoor or outdoor)?

3- What are the connected signals?

There's a great difference between the location of IO modules and the location of IOs themselves (i.e. sensors & actuators).

Normally most of SIMATIC modules (if not all) are certified to be installed in Zone 2. This is also valid for most (if not all) of HMIs.

Only ET200iSP is certified to be installed in Zone 1 with some protection measures.

However, the location and types of sensors and actuators will decide whether you should have an explosion protection method or not.

For explosion protection (briefly),

1- You can use Exd sesnors and actuators (except for Zone 0) then you will be able to use standard IO modules. 

2- Install Ex barriers for Exia and Ex ib signals. Still you can use standard modules in this case.

3- Use an IO module with internal protection (Exia or Exib) like the module you are referring to (6ES7331-7RD00-0AB0) or like the ones of ET200iSP.

Once again, the certificate you are referring to means that ET200MP/S7-1500 modules can be used in Zone 2 but doesn't mean you can connect Exib signals to them.

Please, have a look on 

_{SIMATIC Principles of Explosion Protection}

_{Multimedia Presentation System "Explosion Protection in industrial environments with distributed I/O"}

Hello H-H 

Thank you for this really, really valuable and detailed information

1- What's your application?

It is a chemcial factory

2- Where is your control panel (indoor or outdoor)?

indoor

3- What are the connected signals?

level signals and gas sensors

and thank you sooo much for the last line you typed, now I understand the difference, you're the boss.
