Selection of relay

Relays are widely used in life, but do you know how to choose the right relay?

1. First of all, we need to know the conditions are: the power supply voltage of the control circuit and the maximum current that can be provided; Voltage and circuit in the controlled circuit; The controlled circuit requires groups or forms of contacts.（6v 5 pin relay）

When selecting a relay, the power supply voltage of the general control circuit can be used as the basis for selection. The control circuit should be able to provide enough working current for the relay, otherwise the relay will be unstable.（relay 5 pin 5v）

2. Refer to the relevant information to determine the conditions of use, and find out the type and specification of the relay required. If there is a relay, you can check whether it can be used according to the data, and finally consider whether the size is appropriate.（relay 5v dc 5 pin）

3. Pay attention to the volume of the appliance. If it is used for general electrical appliances, in addition to considering the box volume, small relays mainly consider the installation layout of the circuit board. For small electrical appliances, such as toys and remote control devices, ultra-small relays should be selected.（5v 5 pin relay datasheet）
