    Tips: Working principle of electromagnetic relay

    Electromagnetic replay uses electromagnet to control “on” or “off” status of operating circuit. Thus how an electromagnetic relay works specifically?

    Electromagnetic relay consists of electromagnet, armature, spring, movable contact and stationary contact. When applying voltage to both ends of a coil, the coil will be flowed with current and generate electromagnetic effect. The electromagnet will attract armature to the iron core against tension of spring, so as to pull the movable contact of the armature to the stationary contact (normally open contact, or NO). When users cut off power, attraction of the electromagnet will disappear and the armature will restore its position under tension of the spring to release the movable contract from the stationary contact (normally closed contract or NC). The pulling and releasing are used to control opening and closing of the circuit. Normally open and closed contacts respectively refer to the stationary contract when the coil is cut off from power and the stationery contract when the coil is connected to power.

    Electromagnetic Relay Introduction
    This 8-pin relay features DPDT wiring which you can see clearly through the transparent outer shell. Coil voltage is optional among 12/24/110/220V. Contacts are made from silver alloy for precision operation. It's widely used in auto-control system.

    Functions & Operation of HH52PL Electromagnetic Relay
    The working principle of electromagnetic relay is to use electromagnetic force to drive the opening and closing of contacts. When energized, the coil produces a magnetic field whose strength increases as the current increases. This magnetic field attracts the iron core, causing it to move, thus pushing the contacts to close. When the power is cut off, the magnetic field disappears and the iron core returns to its original position under the action of the spring force, causing the contacts to open. By controlling the on and off of the current, the contacts can be controlled, thereby controlling the circuit. We used 4 light bulbs (220V), a power supply, a push button switch and relay to show you how it works in a more intuitive way.

    Solid electromagnetic relay
    I bought 2 electromagnetic relays. They do make a buzzing noise when active. I used them to control the master valve in my in ground irrigation system. They work just fine.

    High quality electromagnetic relay
    Equal in quality to any relays I've used in industry applications. Handy LED indicator. Electromagnetic relay plugs in and out of the socket smoothly and firmly.

    Compact and easy to wire
    This is a DPDT electromagnetic relay with a 12V coil. The din mount makes it easy to install with others. The ease of having the relay socket labeled. I will definitely be buying these again as I make several control panels.

    When the relay and its lights are on for a while, will unit get too warm?
    I'm a little worried about when the relay and its lights are on for a while, is the unit suppose to get fairly warm? Cause the one I bought from elsewhere gets too warm.
