Signal relays, also called coupling relays, are one of the most commonly used electrical components. These components are found in a variety of devices, from home automation systems to commercial applications. UB2-24NUN is one such signal relay that is designed to handle up to 2 Amps of current. In this article, we will discuss the application field and working principle of UB2-24NUN signal relays.

Application Fields

The UB2-24NUN series is a signal relay designed to handle up to 2 Amps of current. This type of signal relay is suitable for use in a range of applications, including:

• The protection circuits in electronic equipment, such as cell phones and TVs.
• Home automation systems that require reliable low power signals.
• Redundant power supplies, such as UPS systems.
• Industrial application, like power cycles and motor control.
• Lighting control systems.

These signal relays are designed to be used in conjunction with a control system, such as a logic chip or computer, to switch low level signals. UB2-24NUN relays are versatile enough to be used in many different types of electronic systems, and they can be used to switch DC control signals and AC loads like motors.

Working Principle

The working principle of UB2-24NUN signal relays is fairly simple. The main components of these relays include a coil, a pair of contact arms, and a set of pins. When current is applied to the coil, a magnetic field is generated, which causes the contact arms to close, completing the circuit. The circuit can then be used to switch low-level signals, or even to switch larger loads like motors.

The UB2-24NUN series is designed for use with a low voltage DC power supply, usually between 6-12 volts DC. When current is applied to the coil, the contact arms close and the relay is activated. The pins on the relay can then be used to switch loads, such as motors or lights. The UB2-24NUN series also includes a diode protection circuit, which helps protect the relay if the power supply is suddenly disconnected.

When the power supply is disconnected, the contact arms open, disconnecting the load from the power supply. This helps protect the relay from damage, and helps prevent any sudden surges in current if the power supply is suddenly disconnected.

Conclusion

UB2-24NUN signal relays are versatile and reliable components that are used in a variety of electronic systems. They are designed to switch low level signals and can handle up to 2 Amps of current. Their working principle is fairly simple, and they are equipped with a diode protection circuit to help protect them if the power supply is suddenly disconnected. UB2-24NUN signal relays are suitable for use in a range of applications, from home automation systems to industrial applications.
