Electromagnetic relays have a history of more than 150 years since their initial use.
Do you understand the types of electromagnetic relays? I'll introduce it to you today.
Electromagnetic relay includes: DC electromagnetic relay, AC electromagnetic relay, magnetic hold relay, polarization relay. Reed relay, energy-saving power relay.
(1) DC electromagnetic relay: the electromagnetic relay whose control current in the input circuit is DC.
(2) AC electromagnetic relay: the electromagnetic relay whose control current in the input circuit is AC.
(3) Magnetic holding relay: the magnetic steel is introduced into the magnetic loop. After the relay coil is powered off, the keeper of the relay can still remain in the state when the coil is energized, with two stable states.
(4) Polarization relay: a DC relay whose state change depends on the magnitude of input excitation.
(5) Tongue reed relay: the relay that uses the action of tongue spring sealed in the tube with dual functions of contact reed and armature circuit to open, close or convert the line.
(6) Energy-saving power relay: electromagnetic relay whose control current in the input circuit is AC, but whose current is large (generally 30-100A), size is small and power saving.
