Power Relays, Over 2 Amps: MY4ZH-DC24 application field and working principle

Power relays are devices used to control a circuit by a separate low-power signals. They are usually used when a relatively high-power electric circuit needs to be switched on and off at intervals or to control the direction of current flow, and the controlling signal comes from a relatively small or sensitive circuit. The MY4ZH-DC24 is a type of such power relay and has widespread applications in various industrial, lighting, and building automation use cases. This article discusses the MY4ZH-DC24’s application field and working principle.

Application field

The MY4ZH-DC24 is an AC/DC four pole power relay which can switch up to 10A current in DC and AC, and up to 3A in power AC. It is especially fit for DC24V applications, however, a variety of other voltage types can be appropriate as well, depending on requirements. Its convenient plug-in connection and connection to DIN rail allow for easy wiring, making the installation process fast and straightforward.The MY4ZH-DC24 is most suitable for controlling machines and devices that require short, frequent on/off operations such as motors, lamps etc. It can be used in many industries, notably lighting, commercial buildings, and industrial settings. In these applications, the MY4ZH-DC24 acts as a switch that can be remotely or automatically controlled without needing physical access.

Working principle

Like all other power relays, the MY4ZH-DC24 uses a coil to control the switch. When current flows through the coil, it creates a magnetic field and attracts the armature which closes the switch. To turn it off, current simply needs to be interrupted and the armature returns to its initial position, opening the switch.The MY4ZH-DC24 comes with an optional LED indicator that will light up when the relay is in the ON state. Additionally, the MY4ZH-DC24 has a number of coil-related elements that make it suitable for a variety of applications. It can be ordered with force-guided or non-force-guided contacts, and with single-coil or double-coil types.

Conclusion

The MY4ZH-DC24 is an AC/DC four pole power relay which is suitable for switching up to 10A current in DC and AC, and up to 3A in power AC. It is especially fit for DC24V applications and has wide applications in industries which require frequent on/off control, such as lighting, commercial buildings, and industrial settings. The MY4ZH-DC24 works on the principle of a coil controlling the switch, and can be ordered with force-guided or non-force-guided contacts, and with single-coil or double-coil types.
