Relay:
The relay is marked with: AC stands for alternating current, the bottom line 05V is the rated voltage of 5V, and the 30VDC below stands for 30V direct current.
Relay circuit diagram connection: as shown in the middle part of the figure below;
(1) 4 and 5 are D and E;
(2) 2 is normally open, 3 is normally closed;
(3) 1 and 3 form a closed state, and 1 and 2 form an open state;
Reason for using an armature: The armature will not be magnetized.
Freewheeling diode:
》Working principle: (Use knowledge related to induced electromotive force to understand) Therefore, the freewheeling diode needs to be turned on quickly after the circuit is cut off.
