What kinds of relays can be divided according to the principle of action?

1. Electromagnetic relay
A relay that produces a predetermined response by the relative motion of mechanical components under the action of current in the input circuit.
It includes DC electromagnetic relay, AC electromagnetic relay, magnetic holding relay, polarization relay, reed relay, energy-saving power relay.
(1) DC electromagnetic relay: The electromagnetic relay in which the control current in the input circuit is DC.
(2) AC electromagnetic relay: The electromagnetic current relay whose control current in the input circuit is AC.
(3) Magnetic holding relay: The magnetic steel is introduced into the magnetic circuit. After the relay coil is de-energized, the armature of the relay can still maintain the state when the coil is energized, and has two stable states.
(4) Polarized relay: A DC relay whose state changes depending on the polarity of the input excitation amount.
(5) Reed relay: A relay that opens, closes, or switches a line by a action of a reed that is sealed in the tube and has a dual function of a contact reed and an armature magnetic circuit.
(6) Energy-saving power relay: The control current in the input circuit is an AC electromagnetic relay, but its current is large (generally 30-100A), small in size, and power-saving function.
2. Solid state relay
A relay that performs input and output functions by electronic components without mechanical moving parts.
3. Time relay
When the input signal is added or removed, the output portion needs to be delayed or time-limited until the specified time to close or open the relay of its controlled line.
4. Temperature relay
A relay that operates when the outside temperature reaches a specified value.
5. Wind speed relay
When the speed of the wind reaches a certain value, the controlled circuit will be turned on or off.
6. Acceleration relay
When the acceleration of the moving object reaches the specified value, the controlled circuit will be turned on or off.
7. Other types of relays
Such as optical relays, acoustic relays, thermal relays, etc.
