Working principle of Safety Relay / How relays work with electrical safety / Safety relay wiring

Working principle of Safety Relay : How relays work with electrical safety ?
#Safety_relay is a #kill_switch type safety device that operates automatically.
Safety #relay_switch installation is recommended for almost all machines, that are moderately dangerous in operation.
“Dangerous machine” refers to a machine that can cause an accident in the course of its operation injuring its operator and/or damaging the equipment.
Even if a machine's #emergency_stop is pressed, #contact_welding on its normally closed contact points on a #contactor will allow the machine to run continuously.
This will create a dangerous situation, endangering the life of the operator, and can also cause severe damage to the machinery.
Safety relays can effectively isolate quite dangerous machines, when a working contactor or a #relay_opearation is faulty.
The operation and installation of the safety relay are explained here in a descriptive way for easy understanding.

I was looking for a vacuum replacement part and Amazon accidentally came up with safety relays and now I'm here.
I'm not even an electrician, I'm an artist.
Thanks for satisfying my curiosity

Thank you

[@raquelsapalaran2907]

one of the best video tutorial❤

I often encountered these safety relay often bypass because they say that it is hard to troubleshoot due to to many wirings, sensitivity and interlocks. That is why you need to know the importance and the purpose of thess safety relays and the consequences if you did bypassed it

[@ElectroAcademyEA]

Sure. Thank you

Why do we need a Master Relay before the Magnetic contactor?

[@michaelcostello6991]

S12 supplies 24 V to S34 to reset. Is s12 just looking at channel 1 ? Please advise.

[@ElectroAcademyEA]

S11-S12 and S21-S22 are input switches and must be in the closed position for internal contactors K1 and K2 to be closed.
Contactors K1 and K2 (placed inside the safety relay) must be in the closed position for control power to be available at terminal 14.
Although 24 volts for reset power have been connected from S12 of channel 1, the system cannot be restarted without channel 2 enabled.
So, the motor run contactor control power will not be out from terminal 14, without closing both the S11-S12 and S21-S22 switches.

[@michaelcostello6991]

@@ElectroAcademyEA Thank you very much for clarifying this. Please do more safety videos as there as so many different types of safety controllers in industry

[@SusilTech]

Amazing video 👍

Thank you

Emergency stop doesnt stop the circuit ?

[@ElectroAcademyEA]

If the motor running contactor has a contact welding condition, emergency stop cannot stop that faulty contactor from operating.
