Signal relays are an essential part of any automated system, helping to route signals and detect faults. One of the most popular types of signal relays is the UB2-4.5NE, which is designed to work with up to 2 Amps. In this article, we will discuss the application field and working principle of this type of signal relay.

Applications: UB2-4.5NE relays are available for use in many kinds of control systems. They are commonly used for switching power supplies, controlling audio systems, and providing safety interlocks in industrial machinery. They are also used as control signals for electronic pacemakers and other medical devices. In addition, UB2-4.5NE relays can be used to provide security for access-controlled doors and other security systems.

Working Principle: UB2-4.5NE relays operate on a principle of electromagnetic induction. When a voltage is applied to the relay coil, it creates a magnetic field which induces an electric current in the armature. When the coil is energized, the armature is pulled towards it and the contact points within the relay open or close in response. When the coil is de-energized, the armature returns to its resting position and the contact points re-open.

The UB2-4.5NE relays feature a coil voltage range of 24V to 220V DC and contact ratings of 2A or 10A. They are rated with a maximum switching capacity of 230V AC at 2A or 120V AC at 10A. This type of signal relay is designed with a surge suppression feature which helps to protect against electrical surges.

The UB2-4.5NE relays are designed to be used in a wide variety of industrial applications. They provide efficient switching and fault detection, making them an ideal choice for power supplies, audio systems, and other control systems. They are also a reliable solution for providing safety interlocks for automated machinery, as well as providing security in access-controlled systems.

In summary, UB2-4.5NE relays are a reliable and versatile solution for many industrial control systems. They have a wide range of applications, from audio systems to security systems, and feature a wide operating voltage range and a surge suppression feature. They are an ideal choice for providing efficient switching and fault detection.
