Safety relay: definition, characteristics and working principle
Definition and characteristics of safety relay
Safety relay is a special equipment, which is composed of multiple relays and circuits. Its core mission is to act strictly according to preset rules when the system fails, so as to ensure the overall safety of the system. There is a significant difference from ordinary relays. Safety relays have a forced guide contact structure. This unique design is extremely critical because it can still ensure system safety even in the more extreme condition of contact welding, which is a feature that ordinary relays cannot achieve.

Working principle of safety relay
SRC106 safety relay generally uses a dual-channel signal design. Under normal working conditions, the signals of both channels must remain normal for the safety relay to operate stably. Once the signal of any channel is disconnected, the safety relay will respond quickly and stop output immediately. Moreover, the safety relay can only resume work when the signals of both channels return to normal and the reset operation is completed at the same time. This design greatly enhances the safety and reliability of the system and can effectively avoid safety accidents caused by single channel failure.
