Density relay is a type of relay that generates a predetermined response from the relative motion of mechanical components under the b of current in the b circuit.
It includes DC electromagnetic relay, AC electromagnetic relay, magnetic holding relay, comparative relay, tongue spring relay, and energy-saving power relay.
(1) DC electromagnetic relay: An electromagnetic relay in which the control current in the b circuit is DC.
(2) AC electromagnetic relay: An electromagnetic relay in which the control current in the b circuit is AC.
(3) Magnetic retention relay: Introduce magnetic steel 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 energized, with two stable states.
(4) Comparison relay: A DC relay whose state changes depending on the polarity of the b excitation quantity.
(5) Tongue spring relay: A relay that uses the b of a tongue spring sealed in a tube, with a dual effect of contact spring and armature magnetic circuit to open, close, or switch circuits.
(6) Energy saving power relay: An electromagnetic relay in which the control current in the b circuit is AC, but it has a large current (usually 30-100A), small size, and energy-saving function
