    Tips: Functions of signal relay

    Signal relay is composed of two parts: contact system and electromagnetic system. The electromagnetic system consists of a coil, a fixed core, a yoke iron and a movable armature. The contact system consists of moving contacts and static contacts, which plays an important role whether it serves as the core component of relay signal system, or as the interface component of electronic or computer signal system. The functions of signal relay are as follows.

    • Expand the scope of control. When the control signal of multi-contact signal relay reaches a certain value, the multi-circuit can be switched on, disconnected and connected at the same time according to different forms of contact group.
    • Amplification. For example, a sensitive relay can control a large power circuit with a very small amount of control.
    • Integrated signal. When multiple control signals are input into the multi-winding relay in the prescribed form, the predetermined control effect can be achieved through comparison and synthesis.
    • Automatic, remote control and monitoring. Signal relays in automatic devices together with other electrical appliances, can form a programmed control circuit for automatic operation.

    Practical in work
    It has been three months since I bought this 1.5V DC signal relay. And it's also an environmentally friendly product. Although the signal relay is small, it is very practical in work!

    Excately as advertised!
    I purchased these relays to replace the failed units in the electric winch. No issues so far, shipped immediately and got here quickly. It is easy to use and I believe the quality is great. Time will tell.
