Density relay is a type of relay that generates a predetermined response from 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, comparative relay, tongue spring relay, and energy-saving power relay.
(1) DC electromagnetic relay: An electromagnetic relay in which the control current in the input circuit is DC.
(2) AC electromagnetic relay: An electromagnetic relay in which the control current in the input 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 input excitation quantity.
(5) Tongue spring relay: A relay that uses the action 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 input circuit is AC, but it has a large current (usually 30-100A), small size, and energy-saving function
2. Solid state relay abb density relay 1HSB495663-1
A relay whose input and output functions are completed by electronic components without mechanical moving components.
3. Time relay
When adding or removing input signals, the output part needs to delay or * * to the specified time before closing or disconnecting the relay of its controlled circuit.
4. Temperature relay
A relay that operates when the external temperature reaches a specified value
5. Wind speed relay
When the speed of the wind reaches a certain value, the controlled circuit will be connected or disconnected.
6. Acceleration relay
When the acceleration of a moving object reaches the specified value, the controlled circuit will be connected or disconnected.
