1. Electromagnetic relay

A relay in which a predetermined response is generated by the relative movement 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 control current in the input circuit is DC electromagnetic relay.

(2) AC electromagnetic relay: the control current in the input circuit is an AC electromagnetic relay.

(3) Magnetic holding relay: the magnetic steel is introduced into the magnetic circuit, and after the relay coil is powered off, the armature of the relay can still maintain the state when the coil is powered on, with two stable states.

(4) Polarized relay: a DC relay whose state changes depending on the polarity of the input excitation.

(5) Reed relay: Use the action of the reed sealed in the tube, with the dual role of the contact reed and the armature magnetic circuit to open, close or convert the line of the relay.

(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 size, and power-saving function.
