Power Relays, Over 2 Amps

LY4-AC100/110 are power relays with a rated switch load capacity of over 2 Amps. The relays provide user-friendly access to a wide range of applications for both industrial as well as home use. In this article, we will discuss the application fields and working principle of LY4-AC100/110.

Application Field

LY4-AC100/110 relays can be used for a wide range of applications. The relays can be used for controlling high voltage and current loads, such as electric motors, pumps, lighting, and heating systems. The relays can also be used to control low voltage and low current applications, such as computers, ovens, water heaters, washer and dryers. Furthermore, the relays are suitable for controlling high-power electronic equipment, such as robotics, industrial processes, and audio-visual devices.

Other applications where the relays can be used include power transmission lines, train control systems, and security systems. Relays can also be used in the same way as conventional relays for controlling the switching of motors, contactors, and other types of mechanical switches. The relays can also be used for current protection and voltage monitoring.

Working Principle

The LY4-AC100/110 relay is of the electromechanical type, and uses a coil and a contact to switch low voltage and low current devices. The current in the coil creates a magnetic field, which attracts the contact and engages the circuit. The contact can be disengaged by reversing the current flow in the coil, or by physically deactivating the relay. The contact can be closed or open to allow current flow or block current flow.

The relays have two electromechanical contact points, which are usually referred to as ‘changeover points’. These contacts allow the user to control the logic of two separate circuits. When the relay is switched ‘on’, the contact points are ‘closed’, allowing current flow. When the relay is switched ‘off’, the contact points are ‘open’, preventing current flow. The relays can also be used to ‘delay’ the action of the contact points, by introducing a time delay before the contact points are switched ‘on’ or ‘off’.

The relays also provide the user with the ability to switch off the relay in case of excessive current or voltage fluctuations. This feature is enabled by a ‘voltage protection’ circuit. When the voltage or current exceeds a certain limit, the voltage protection circuit switches off the relay, thus protecting the circuit from damage.

Conclusion

LY4-AC100/110 relays are ideal for a wide range of applications where remote, automated, or manual control of circuits is required. They are easy to install and maintain, as well as being cost-effective. The relays also provide user friendly access to a range of advanced features, such as voltage monitoring and current protection circuits. This makes the relays suitable for applications ranging from industrial and domestic to security and pro audio-visual systems.
