How does a safety relay work

WebThe “relays” embedded in electrical products work in a similar way; they receive an electrical signal and send the signal to other equipment by turning the switch on and off. For example, when you push the button on a TV remote to watch TV, it sends an electrical signal to the “relay” inside the TV, turning the main power ON. A safety relay detects wire breaks and faulty contactors/actuators by sending out electrical pulses through the wiring. By measuring flow of current the safety relay checks for welded contact sets and wire breaks. This is all done with timing. Timing is the other fault detection method safety relays use.
