When choosing the Cheap 12v relay, you should mainly consider factors such as the type of power source, the rated voltage and rated current of the contacts, the rated voltage or rated current of the coil, the method and number of contact combinations, the pull-in time and the release time.

Cheap 12v relay uses its normally open or normally closed contacts to control one or more circuit switches with larger load currents (mainly contactors and circuit breakers), as control buttons or micro switches and circuit switching elements for larger load currents A control signal transmission link of Zhizheng;
Cheap 12v relay is used to directly control smaller current circuits or electrical equipment, such as lights, indicator lights, electric bells, small-capacity electric stoves, small-capacity motors, small fans, etc. It is equivalent to a small-capacity contactor.
Cheap 12v relay is mainly used in various protection and automatic control devices, the number of contacts and the capacity of the protection and control loops.
■ Its function is fully compatible with DZY electromagnetic intermediate relay.
■ AC and DC dual purpose
■ Fast rail installation structure, suitable for all kinds of rail installation.
■ Screw crimping terminal.
