Power relays are electrical relays that use a small electrical current to switch or regulate the larger current flowing in a circuit. The MY4N-J DC12 relay is a power relay designed to switch AC or DC current over 2 amps and is primarily used in automation and control applications. The MY4N-J DC12 relay can be operated either manually or with a digital control signal, delivering reliable, precise, and cost-effective switching power in a wide range of applications.

Construction of the MY4N-J DC12

The MY4N-J DC12 features an electromechanical contact system enclosed in a dustproof, moisture-resistant and heat-resistant plastic body. It has a low-power DC coil and four contacts, consisting of three normally open contact points and one normally closed contact point. The contacts can be connected to a load or device, enabling a circuit to be switched on or off by applying or interrupting power to the contacts. The contacts are made of durable metal for reliable switching performance, even in high-temperature environments.

Applications of the MY4N-J DC12

The MY4N-J DC12 power relay is suitable for a range of applications, mostly in automation and control systems. It can be used to switch small AC and DC current over 2 amps in motor control, lighting, HVAC, home automation, factory automation, process control, and retail control systems. It can also be used in automotive applications, including air conditioning, car diagnostic systems, electric window control, audio systems, and engine control.

Working Principle of the MY4N-J DC12

When AC or DC power is applied to the relay, a magnetic field is generated which causes the magnetic armature to move. The movement of the armature opens or closes the contacts, depending on whether or not the relay is energized. When the transfer of power is interrupted, the magnetic armature returns to its original position restoring the contacts to their original state. The MY4N-J relay has a mechanical force that maintains the closed contacts in place, preventing them from opening again until it is triggered by an external signal.

Benefits of the MY4N-J DC12

One of the main benefits of the MY4N-J DC12 is its small size and low power consumption, meaning that it can be used in a range of applications without needing additional power sources. It is also designed for reliable and precise switching performance, providing a consistent and reliable signal in a range of conditions. Additionally, the MY4N-J DC12 is inexpensive, making it a cost-effective solution for a range of applications.
