This is an normal use example of a safety relay , you may like to add them to this video . It takes two hands to activate these switches, minimizing the risk of accidental equipment start up. A complete system requires two switches, one safety relay, and two outlet boxes. Safety relays control the two switches by sending an output signal when both switches are activated within 0.5 seconds of each other. Self-monitoring circuitry offers additional protection-if any part of the system fails, the entire system shuts down until repaired.
I am using siemens nxair breaker in that they implemented 3sk1111-1aw20 safety relay for two e stops ..now when I release these two e stop switches the breaker is getting auto close and it's causing the 5.5 mw motor to run..please give the solution for this problem
Yes, they are called safety PLCs. Their usement is still concentrated on safety, but user could implement individual logic inside it depending on specific project requirements. Safety PLCs have also a fieldbus interface to communicate with other PLCs. You may take a look at ABB Pluto series for example…
You forgot to mention that safety relay has positive guided contacts. In case of welding of NO contact, all contacts are immovable and hence guarantee that no safety is comprised.
Honestly;
whenever I login to UA-cam for self-turoring and find your good-looking face i like the video before I even watch it!
keep up the good job!
Wow, thank you!
Also wondering when you guys are doing Pt. 2! Thanks!
1 year after lol

If we ever have 1st contact with aliens, i want this guy to do the talking.
Still no part 2. Thanks guys.
Can you give a practical exam? Where a safety relay must be used rather than a standard one and why?
I could not find the part 2,
Still waiting on Part 2. Any word on when it might drop?
Are there any programmable Safety Relays that are controlled using microcontroller?

When are you releasing part 2?
Than you for your effort , i learn a lot.
still waiting for part 2

They must be studying how these safety relays work. Because there is no part 2 even 5 months later.
They have it now xd
