Static relay and we usually encounter the relay in the structure, function and use of the way there are those differences? What is his advantage?
The use of the two different principles of subtle differences.
Static intermediate relays are used in a variety of protection and automatic control circuits. Such relays by the electronic components and precision small relays, etc., is the power series of intermediate relays replacement products of choice. Static relay without contact, no electromagnetic coil, also known as solid state relay.
As long as the coil at both ends with a certain voltage, the coil will flow through a certain current, resulting in electromagnetic effects, the armature will be attracted by the role of electromagnetic force to overcome the return of the spring to pull the iron core, Moves the contact with the static contact (normally open contact). When the coil is powered off, the electromagnetic force will disappear, the armature will return to the original position of the spring, so that the movable contact with the original static contact (normally closed contact) release. So that pull, release, so as to achieve the circuit in the conduction, cut off the purpose. For the relay "normally open, normally closed" contacts, it can be distinguished: relay coil is not in power when the state of the static contact, known as the "normally open contact"; in the state of the static contact As "normally closed contact". Relays generally have two circuits, low voltage control circuit and high voltage working circuit.
Electromagnetic relay generally consists of iron core, coil, armature, contact reed and other components.
