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
