Signal relays, up to 2 amps are widely used in a variety of applications including connection and disconnection of circuits, monitoring and measurement, and controlling. The most common types of signal relays are the UB2-4.5NE-L. This type of relay is particularly useful in situations where a low level of current is needed, such as low voltage control. This article will provide a brief overview of the UB2-4.5NE-L application field and its working principle.

The UB2-4.5NE-L is a small signal relay with a contact rating of 4.5 Amps. It has a contact configuration that provides both normally closed and normally open connections, which makes it suitable for a wide range of applications. It also has an LED indicator and a variety of mounting options, such as panel mount and surface mount. The UB2-4.5NE-L is particularly useful for applications that require a low level of current, such as low voltage control, and can be used in both AC and DC circuitry.

The UB2-4.5NE-L can be used in a variety of applications, including connection and disconnection of circuits, monitoring and measuring of current, and controlling. In connection and disconnection of circuits, the UB2-4.5NE-L provides a reliable way to switch circuits on and off. It can also be used to monitor and measure current by connecting it to a voltage source. Additionally, it can be used in controlling applications, such as motor control, water monitoring, and light control, by providing a switchable connection between a control device and the circuit.

The UB2-4.5NE-L has a very simple working principle. When the voltage source connected to it is higher than the relay\'s rated voltage, called "pickup voltage", the relay coil is energized and the contacts close. The contacts will stay closed until the voltage drops below the rated voltage. When the voltage drops, the relay coil is de-energized and the contacts open. This on and off operation is repeated as long as the voltage source is applied to the relay.

In summary, the UB2-4.5NE-L is a small signal relay with a contact rating of 4.5 Amps and a contact configuration that provides both normally closed and normally open connections. The UB2-4.5NE-L is particularly useful for applications that require a low level of current, such as low voltage control. It can be used in a variety of applications, including connection and disconnection of circuits, monitoring and measuring of current, and controlling. The UB2-4.5NE-L has a very simple working principle. When the voltage source connected to it is higher than the rated voltage, the relay coil is energized and the contacts close. When the voltage drops, the relay coil is de-energized and the contacts open.
