The purpose and classification of the control relay is an automatic electrical appliance. It is suitable for long-distance connection and disconnection of AC and DC small-capacity control circuits and is used for control, protection, and signal conversion in electric drive systems. The input quantit... read more
The function of the time relay is very wide and wide, and there are many types, mainly used for circuit control, which can also be called a circuit switch, then, will the time relay work make a sound, the following is Explain this problem to everyone. There are many types of relays.Generally, mechan... read more
1. Before using the relay, check whether there is any damage during transportation, that is, set it at the first setting point, turn the movable system in the direction of the magnetic pole by hand, and then release it, the movable system should be turned back to the original position Until it stops... read more
The DC contactor adopts a modular design, which can assemble the number of contact paths required by the customer and the form of contacts required by the customer (normally open, normally closed and converted) with the fewest parts; the contact breaking voltage of this series of products is high , ... read more
1. DC contactor It is generally used to control DC electrical equipment. DC current is applied in the coil. The operation principle and structure of DC contactor are basically the same as that of AC contactor. Because it can quickly cut off the AC and DC main circuits and can be frequently connected... read more
