  • What are the technical parameters of the main products of the relay

    The technical parameters of the main products of the relay have five aspects. 1. Rated working voltage It refers to the voltage required by the coil when the relay is working normally. Depending on the model of the relay, it can be either AC voltage ...

  • What is the role of the magnetic latching relay in the device

    Magnetic latching relays are very similar to polarized relays, with two static contacts, one moving contact, and multiple coils, which are equivalent to a "bistable relay" (which can also be regarded as a "current-driven" SPDT switch") The polarized ...

  • What are the main classifications and functions of voltage relays

    The main classification and functions of voltage relays: 1) Electromagnetic relay: use the circuit in the input circuit to connect the core of the electromagnet 2) Solid-state relay: refers to a kind of relay in which electronic components perform th...

  • What issues should be paid attention to when choosing a relay

    When selecting a relay, factors such as the type of power supply, the rated voltage and rated current of the contacts, the rated voltage or rated current of the coil, the combination and number of contacts, the pull-in time, and the release time are ...

  • Features and applications of voltage relays

    Voltage relay is a commonly used electromagnetic relay, and voltage relay is used for voltage protection and control of power drag system. The coil is connected to the main circuit in parallel to sense the line voltage of the main circuit; the contac...

  • What is the purpose of the current relay electromagnetic

    The electromagnetic current relay is an electromagnetic instantaneous overcurrent relay, which is widely used in the circuit of the secondary circuit relay protection device of the power system as an overcurrent starting element. The electromagnetic ...

  • What is the function of the voltage relay

    A voltage relay is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.Voltage relay structure and prin...

  • How does a voltage relay work

    Electromagnetic relays are generally composed of iron cores, coils, armatures, contact reeds, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, resulting in an electromagnetic effect, and ...
