Signal relays are widely used devices designed to switch one or more electrical signals between two nodes. The Ub2-24Nu-L signal relay is a part of this family of components, typically used for low-power relaying tasks, with up to 2 Amps of current. This article will explore the application field and the working principle of this type of signal relay.

A. Application Field of Ub2-24Nu-L Signal Relay

This signal relay is suitable for use in a variety of low current applications. These applications can be highly diverse, ranging from factory automation and automotive control systems, to home appliance control and the protection of commonly used electronic components such as relays and motors. Accessories for devices such as relays should be chosen to be compatible with the voltage and current level of the particular application. The Ub2-24Nu-L is generally employed with signal voltage ratings from DC 5-24V and a load current of up to 2 Amps, making it suitable for a variety of applications.

In addition, it is specifically designed for intermittent duty applications. This means it can be utilized for applications such as automotive injectors, hall effect sensors and timers, when connected to a digital signal. In such scenarios, the Ub2-24Nu-L signal relay is activated only for a short period of time (up to 10 seconds).

Due to its small size and load current rating, the Ub2-24Nu-L signal relay can also be used in applications suitable for miniature relays. These can include everything from cell phone systems to digital cameras.

B. Working Principle of Ub2-24Nu-L Signal Relay

The Ub2-24Nu-L signal relay is a single-pole, double throw (SPDT) signal relay, the working of which is based on a magnetically actuated armature. The device has trips composed of two NC (normally closed) contacts and one NO (normally open) contact. When the relay is energized, the armature is drawn to the magnet, connecting the NO contact to the contact associated with the actuating coil. This allows the circuit to be completed, thus switching the signal.

The Ub2-24Nu-L relay is a low-power device, and as such requires additional circuitry to drive it. This usually involves providing the relay with a signal, such as a pulse current from a microcontroller or an external device. The pulse current is the force which energizes the device in order to switch the NO contact.

Although the Ub2-24Nu-L signal relay is primarily used for intermittent duty applications, there are other applications in which it can be employed. These include switch mode power supply control, and switching of contactors or motors. It can also be used in applications requiring multiple relays, and can be combined with other relays or other devices.

The Ub2-24Nu-L signal relay has a wide range of applications, due to its small size, low power consumption, and the ability to switch other components easily and quickly. It is a useful component for numerous low current applications, and can be used in various types of systems.
