1. Classified according to the principle of action
The electromagnetic relay drives the armature and the movable part to act through the suction generated by the current in the relay coil in the electromagnet and changes the working state of the contact system. Such as DC stepless relays, DC polarized relays, AC relays, binary differential relays, etc.
Induction relays operate by interacting with an alternating magnetic field with another alternating magnetic field to produce eddy currents in the wing plates of the moving part of the relay. Such as AC binary two-position relay, etc.
The thermal relay uses the current to heat the bimetal sheet, which has the weakness of one-way bending, and the relay takes advantage of this characteristic to act.
2. Classified according to the working current
DC relays work in DC circuits, and most signal relays belong to this category.
AC relays work in AC circuits, such as AC filament conversion relays, FD electric coders, JRJC binary two-position relays, rectifier relays, etc.
AC and DC relays can be used in AC and DC circuits, such as general relays, various thermal relays, etc.
3. Classification according to action speed
The action time of the quick relay armature is less than 0.1S. Most signal relays are in the ratio range.
The normal action relay armature action time is 0.1-0.3S. Most signal relays fall into this range. The action time of the slow relay armature is more than 0.3s. Such as stepless slow discharge relays, thermal relays, safety semiconductor time relays, etc.
