1. Select the rated working current of the electromagnetic relay coil: For the DC electromagnetic relay driven by transistors or integrated circuits, the rated working current of the coil (generally 2 times the suction current) should be within the output current range of the driving circuit.

2. Select the contact type and contact load of the electromagnetic relay: the same type of relay usually has a variety of contact forms to choose from (electromagnetic relays are: single group contact, double group contact, multiple group contact and normally open contact, normally closed contact, etc.), and the contact type suitable for the application circuit should be selected.

3. Select the power supply voltage of the electromagnetic relay coil: When selecting the electromagnetic relay, you should first choose whether the power supply voltage of the relay coil is AC or DC. The rated working voltage of the relay should generally be less than or equal to the working voltage of its control circuit.

4. Choose the appropriate volume of the electromagnetic relay: The size of the volume of the Omron relay is usually related to the size of the contact load of the Omron relay, and the size of the relay should be selected according to the requirements of the application circuit.
