In industrial control lines and current home appliance control lines, there are often intermediate relays. For different control lines, the role of three-phase relays is different. The functions of the intermediate relays are common in the following ways: 1. Replace the small contactor The contacts ... read more
1. Introduction to magnetic latching relays The magnetic latching relays is also a kind of relay, but it has more stable performance than other relays, and has a smaller volume and a stronger carrying capacity. The magnetic latching relays is essentially an automatic switch that can automatically tu... read more
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
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
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
