What is the relay used for? Relay is a kind of protection element, an automatic switching element with isolation function. The relay can be used for switching, breaking, and connecting multiple circuits, which can expand the control range. With sensitive relays and intermediate relays, high-power ci... read more
The structure and working principle of an electromagnetic relay are similar to that of a contactor, mainly composed of an electromagnetic mechanism and contacts. Electromagnetic relays are also available in DC and AC. The suction value and release value of the relay can be adjusted within a certain ... read more
How to choose the power relay correctly, which is divided into 4 steps, I hope it will be helpful to everyone's study. 1. Measuring contact resistance Use the resistance file of the universal meter to measure the resistance of the normally closed contact and the moving point. The resistance value sh... read more
Circuit board relay is a miniaturized electronic control device, in which the circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. The relay has a control system (also ca... read more
A relay is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specified requirement. There are many types of relays, to... read more
