Relay Sockets

JRE400301 Application Field and Working Principle

Relay sockets are combinations of individual machines consisting of relays and timers connected together to achieve complex automation or control tasks. JRE400301 is a 4-harness relay socket, Each harness consists of one normally open contact and one normally closed contact.

Application Field

JRE400301 relay sockets are mainly used in industrial automation, such as starting of air compressors, control of time and temperature, etc. In addition, this relay socket can also be used in semiconductor chip processes to provide reliable control of complex operations. The application field of this type of relay socket is vast and can always be leveraged to facilitate many types of industrial tasks.

Working Principle

JRE400301 relay sockets work by activating one of two poles when a certain operation is activated. When a coil is energized, the normally open contact closes and the normally closed contact opens. When the coil is de-energized, the opposite action occurs, and the normally closed contact closes and the normally open contact opens. This allows for various types of operations to occur in order to achieve various types of control or automation tasks. The main feature of JRE400301 relay sockets is the self-locking function. The self-locking function ensures that the relay contact is reliably settled after power failure. Once the coil is energized, the contact maintains its original state even after the power is cut off, thus enhancing the reliability of the device.The self-locking function is implemented by the mechanical device of the relay. When the coil is energized, a movable iron core will be attracted and locked in the right position of the magnetic field inside the relay. The movable iron core locks the magnetic field, and the switch is then respectively in a stable state with each coil energized or de-energized. The coil of the relay can be energized or de-energized by signals from an external voltage or an internal power supply. When an external voltage is applied to the coil, the voltage drives the current in the coil and generates a magnetic field. The magnetic field attracts the movable iron core and settle into the final state. The current is generated by either a low voltage DC or an AC signal, which can be provided by external or internal power supplies.

Conclusion

The JRE400301 relay socket is a versatile device with a wide range of applications in industry and semiconductor chip processes. It allows for complex tasks and operations to be controlled and automated. It also features a self-locking function that ensures that the relay contact is securely settled after power failure. This type of relay socket is a valuable tool in industrial automation and its reliable control is essential for its success.
