    Relay selection and precautions

    1. First understand the necessary conditions a. control circuit power supply voltage, the maximum current that can be provided; b. voltage and current in the circuit being controlled; c. The controlled circuit needs several sets and what forms of contacts. When a relay is selected, the power supply ... read more

    Is the car relay hot is normal

    The car relay is hot. From the perspective of physics, it is a process in which mechanical motion generates heat and mechanical energy is converted into heat. This is a normal phenomenon. This is also the reason why radiators are installed in many machines. When a large amount of heat is generated d... read more

  • The difference between solid state relays and mechanical relays

    The difference between solid state relays and mechanical relays

    Relays have solid-state relays and mechanical relays. What is the difference between these two relays? Electromagnetic relays and solid-state relays are not afraid of earthquakes; the former are afraid of magnetism and the latter are afraid of induction; one is low and the other is high; one is low ... read more

    The role of general purpose relays

    What is a general-purpose relay? General-purpose relay is a relatively abstract concept in physics. Many people may not understand what a general-purpose relay is. The relay is usually used in an automatic control circuit. It actually uses a small current to control high-current operation. An "autom... read more

    How to set up the electromagnetic relay

    The structure and working principle of the electromagnetic relay are similar to those of the contactor, and are mainly composed of an electromagnetic mechanism and a contact. Electromagnetic relays are also available in both DC and AC. The suction and release values of the relay can be adjusted with... read more
