RoHS 12 Volt Universal Car Relay Protection Fuse Sensitivity Type

Definition of relay:

A relay is a component that produces a predetermined jump in one or more of its outputs when the input reaches a specified condition. Generally, it can be simply understood as a specified electrical signal is applied at the input end, and its output end turns on and off a switch of the controlled circuit. Most of the relays used in automobiles are electromagnetic relays.

Application Scenarios of Automotive Relays:

Use scenario 1, to realize the opening and closing of the switch through small current control, and prevent the ablation of the switch contacts by the large current in the circuits. Scenario 2 to implement auxiliary functions, such as flashing relay, wiper relay, etc.

Selection of relays:

Automotive relays generally have a separate special material number for management in an OEM factory. Even if there is no one, there are reliable suppliers to supply them. When selecting relays, try to use the company's existing products for control. Generally speaking, when selecting a relay, the main considerations are the contact form of the relay, the type of load, the voltage that the contact can withstand, the magnitude of the current, the pull-in/release voltage of the coil, and the use environment.

1. Contact form: choose the appropriate contact form according to the usage.

2. Maximum Switching Voltage: The maximum load voltage that the relay contacts can switch.

3. Maximum switching current: the maximum load current that the relay contacts can switch

4. Maximum continuous current: The maximum load operating current that the relay contacts can withstand. This value varies under different ambient temperatures.

5. load type

Universal Automotive Relay Introduces:

A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity meets the specified requirements. It has an interactive relationship between the control system and the controlled system. Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
