New electromagnetic relay The new electromagnetic relay includes non magnetic holding relay and magnetic holding relay. Non magnetic latching relay is a monostable relay.
The contact output state of relay coil changes under the action of specified voltage excitation, but the contact output state returns to the initial state after the coil excitation is canceled.
Magnetic latching relay is a bistable relay, which is divided into single coil structure and double coil structure. The coil excitation is electric pulse. For the relay with single coil structure, when the contact output state of the coil changes under the action of the specified voltage excitation and the coil excitation is cancelled, the contact can remain in the existing state. To change the contact output state, a specified reverse voltage excitation shall be added to the coil.
For the relay with double coil structure, when the contact output state of the first coil changes under the action of the specified voltage excitation amount and the coil excitation is cancelled, the contact can remain in the existing state.
To change the contact output state, the specified voltage excitation amount needs to be added to the second coil. |
