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.

  交流继电器工作在交流电路中,如交流灯丝转换继电器、FD型电动发码器、JRC型二元二位继电器、整流式继电器等。

  交直流继电器在交直流电路中均能使用,如通用继电器、各种热力继电器等。

3. Classification according to action speed

  速动继电器衔铁动作时间小于0.1S。大部分信号继电器属此范围。

  正常动作继电器衔铁动作时间0.1——0.3s。大部分信号继电器属此范围。

  缓动继电器衔铁动作时间超过0.3s。如无极缓放继电器、热力继电器、安全型半导体时间继电器等。
