What is the function and working principle of 12V small relay?

Small relays are devices that bai controls high voltage or high du current through low voltage and small current. Dao will be used in many places of 12V, which must be matched with your control voltage, such as automobiles, air conditioners, home appliances, industrial control, etc.

Time delay relays are parts that activate a multitude of appliances, machinery, and equipment. Some of the applications include:

· Motor vehicles

· Furnace fans

· Conveyor belts

· Dispensing equipment

· Warning systems

Timing relays have a built-in time-delay function. Triggered in various ways, time delay relays minimize the energy used to start large industrial machinery or can switch on and off light switches.

Time delay relays can also make sure that the different parts of a machine start separately at predetermined times, such as:

· Production

· Safety

Safety

As a safety application example, furnaces require ventilation to get rid of fumes and avoid the possibility of explosions. A time delay relay provides a scheduled window to clear noxious gases from the chamber.

Generally, a time delay relay is triggered either by opening or closing a circuit or by providing an input current. The trigger signal can be either a dry-contact control switch, such as a float switch, limit switch, or push button; or with voltage.
