Working principle of 24V relay.

24V relay can only be used in working systems with 24V power supply, and can be combined with 12V relay or used separately. There is an internal structure diagram on the side of the relay, mainly used to drive external high-power loads, commonly used for low side drive output functions. Its working principle is that the 85 # heel 86 # pin energizes the internal coil through the voltage difference, the coil closes the internal switch through electromagnetic induction, connects the 30 # heel 87 # pin, and drives the external high-power load to work normally.
