The main purpose of the intermediate relay has two, one is with the normally open or close contact to control one or more large load current (10A) circuit switch (main contactor and circuit breaker), as the current control circuit button or micro switch with larger load a control signal. Among the elements of the transmission link, it is called the "relay"; the other is used to directly control the small current (10A or 5A) line or electrical equipment, such as lights, lights, bells, small capacity, small volume, small electric motor fan, then the equivalent of a small capacity contactor (such as the CJ10 series 20A and 10A two specifications).
AC relay is a type of domestic varieties compared to traditional ZJ7 4/4, one of the "ZJ" stands for "relay", "7" for the design of serial number, "4/4" said there are 4 pairs of normally open contact and the normally closed contact of 4.
There are also a variety of specifications, some varieties can be inserted and through the combination way, will increase the number of touch.
Intermediate relay excitation coil voltage is 12V, 24V, 36V, 110V, 220V, 380V and so on, contact rated current is 5A, the maximum is 10A.
