When working, adding a certain control signal to the input circuit can control the switching state between the two ends of the output circuit. In order to prevent the influence of the output end on the input end, the circuit between the input end and the output end in the electrical soli……

Time relay refers to a relay whose output circuit needs a specified accurate time to jump (or contact action) after the input action signal is added (or removed). It is an electrical component used in low voltage or low current circuits to connect or disconnect high voltage and high curr……

1. Measure the contact resistance. Use the resistance gear of the multimeter to measure the resistance of the normally closed contact and the moving point, and the resistance value should be 0; The resistance between the normally open contact and the moving point is infinite. It can be d……

Control relay is a kind of automatic electrical appliance, which is suitable for long-distance switch and DC small capacity control circuit, and is used for control, protection and signal conversion in electrical transmission system. The input quantity of relay is usually electric quanti……

1. What is a relay? In fact, the relay is a kind of input quantity. When a certain input quantity such as electricity, magnetism, sound, light or heat reaches a specific value, its output will change by leaps and bounds. Relays have control systems (also known as input circuits) and cont……

1. When used for AC inductive load communication, the output terminal will release high transient voltage and surge current, which will cause the solid-state relay to turn on or off or damage. Usually, voltage operating elements with special clamping voltage, such as multi wire zener dio……
