    Relay classification
    Created:2014-6-18 11:57:42  |  Views:77

    In 1, according to the working principle of relay or structural feature

    ( 1): use of electromagnetic relay input circuit within the iron core of the electromagnet and armature road is generated between the suction effect and working in an electrical relay.

    ( 2): a solid state relay electronic components to perform its function without mechanical motion component, input and output isolation is a relay.

    Temperature relay ( 3 ): when the outside temperature reaches a given value and action relay.

    ( 4) reed relay : the use of sealing in tube with electric shock, reeds and the armature magnetic dual role of the reed moves to open, close or convert circuit relay.

    ( 5) a time relay: when add or remove the input signals, output to delay or limit to the specified time to close or open the controlled circuit relay.

    ( 6): high frequency relay for switching high frequency, RF circuit with minimum loss relay.

    ( 7) polarized relay : a polarized magnetic field and control the current through the coil of the magnetic field generated by the synthetic effect of the relay action. Relay action direction depends on the control of the direction of current flow through the coil.

    ( 8) other types of relay relay relay: such as light, sound, thermal relays, meters relay relay, Holzer effect, differential relay.

    In 2, according to the shape and size classification of relay

    ( 1) miniature relay

    ( 2) subminiature relay

    ( 3) miniature relay

    In 3, according to the load relay classification

    ( 1) a power relay

    ( 2) weak power relay

    ( 3) in power relay

    ( 4) large power relay

    In 4, according to the relay protection feature classification

    ( 1) sealed relay

    ( 2) closed type relay

    ( 3) open type relay
