The intermediate relay is essentially a voltage relay, which operates according to the presence or absence of the input voltage. Generally, there are many pairs of contacts, and the rated current of the contact capacity is about 5A to 10A.
The intermediate relay is small in size and has high action sensitivity. Generally, it is not used to directly control the load of the circuit, but when the load current of the circuit is below 5A ~ 10A, it can also replace the contactor to control the load. There are many contacts in the intermediate relay. There are 8-pin, 11-pin, and 14-pin relays. The number of different pins is actually divided into two types of opening and two closing, three opening and three closing, and four opening and four closing types. For details, see The pinout diagram on the product.
The time relay is a very important component in the electrical control system. In many control systems, it is necessary to use the time relay to realize the delay control and play the role of delay closing or opening in the circuit.
The input quantity of the current relay is current, and it is a relay that operates according to the magnitude of the input current. The coil of the current relay is connected in series to the circuit to reflect the change of the circuit current. The coil has few turns, the wire is thick, and the impedance is small.
