Brand :ABB

Model :3HAB8859-1/03A

ABB 3HAB8859-1/03A density relay A relay that produces 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, more chemical 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, 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 

(4) 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, power-saving function.Solid state relay abb density relay 1HSB495663-1

A relay in which the input and output functions are performed by electronic components without mechanical moving parts. 3. Time relay

When adding or removing the input signal, the output part needs to delay or close or disconnect the relay of its controlled line until the specified time. 4. Temperature relay

Relay that operates when the external temperature reaches the specified value.5. Wind speed relay

When the speed of the wind reaches a certain value, the controlled circuit will be switched on or off. 6. Acceleration relay

When the acceleration of the moving object reaches the specified value, the controlled circuit will be switched on or off.
