Safety relays are required for safety circuits to protect people and machines, and the use of safety relays in Europe is mandatory.
The so-called "safety relay" has a regular action when it fails, and it has a forced guiding contact structure, which ensures safety even in the case of contact sintering, which is completely different from the general relay.
There are a variety of safety relays, which are mainly used in emergency stop circuits, specifically in safety circuits. It ensures that the control circuit leads to safety in some emergency situations, not necessarily emergency stop. Emergency stop is a common type. Security measures. For example, sometimes the shutdown is safe, but the ventilator in the underground coal mine is turned to the full speed-power frequency instead of the shutdown after the inverter is broken.
