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 stop... 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
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
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, t... read more
