We should all be aware of the role of the relay. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, which will produce electromagnetic effects. The armature will overcome the pull of the return
Does the relay make a sound when it works? The answer is yes. The role of relays is very wide, and there are many types of relays. We can see relays in circuit control. The role of relays is to be used as a switch. Because the action is the pull of t
What are the requirements for component sensitivity of power relays: 1. Voltage excitation sensitivity At the most sensitive angle and 0.5 times rated current, the minimum operating voltage of power relays: rectifier type relays should not be greater
What factors need to be considered when selecting a power relay: 1) The voltage and current in the controlled circuit; 2) When selecting a power relay, the power supply voltage of the general control circuit can be used as the basis for selection. Th
What are the steps of relay wiring: 1. Find out the coil pins. Use a multimeter to measure the resistance between the pins. The two pins with a resistance value of hundreds to 1K ohms are coil pins. Note that the coils of some relays are divided into
