MK3PN-5-I AC6

Power Relays, Over 2 Amps

The MK3PN-5-I AC6 is a mid-range power relay that is designed primarily for use in industrial automation and control systems. The relay is capable of switching current in excess of two amperes, making it suitable for a wide range of applications. This article will examine the application field and working principle of the MK3PN-5-I AC6.

Application Field

The MK3PN-5-I AC6 is most commonly used in industrial automation and control systems such as PLC (Programmable Logic Controllers) and SCADA (Supervisory Control and Data Acquisition systems). It is also suitable for use in a variety of other industrial and commercial applications. The relay is designed to switch AC line voltages between 0 and 250 volts, and line currents up to 2.5 amperes. It is rated for a continuous duty cycle of up to 100%, making it suitable for applications that require high current loads.

The MK3PN-5-I AC6 is also designed to provide a range of other features that make it suitable for use in a range of applications. The relay offers two switch contacts, allowing for a variety of control configurations. It also includes a coil voltage protection circuit that prevents damage from voltage spikes. The relay also features dual LED indicators that can be used to indicate whether the relay is in the open or closed position. Lastly, the MK3PN-5-I AC6 is designed to be able to withstand vibration and shock, making it suitable for harsh operating environments.

Working Principle

The MK3PN-5-I AC6 is a simple solid-state relay that operates on the basic principle of electromagnetism. When a voltage is applied to the input side of the relay, the input coil is activated. This creates an electromagnetic field which in turn activates the movable plunger. The plunger then moves, closing the internal circuit and thus switching the AC line current between 0 and 250 volts. The LED indicators provide a visual indication of the relay\'s switch status.

The MK3PN-5-I AC6 also incorporates a protection circuit that prevents damage to the relay from voltage spikes. This is achieved by incorporating a zener diode that triggers when the voltage on the input side of the relay exceeds a certain level. The zener diode then redirects the excess voltage, protecting the relay from damage and ensuring its longevity.

Conclusion

The MK3PN-5-I AC6 is a solid-state power relay designed primarily for use in industrial automation and control systems. The relay is capable of switching AC line voltages between 0 and 250 volts, and line currents up to 2.5 amperes. It also includes a number of features, such as dual LED indicators and voltage spike protection, that make it suitable for a variety of applications. The basic working principle of the relay is based on electromagnetism, and it operates by activating an internal coil, which in turn activates the movable plunger and switches the current between 0 and 250 volts.
