Signal relays are electronic switches used to turn on or off electrical and electronic devices. Their switching capabilities are determined by the electrical and mechanical properties of the relay contacts. The UB2-3SNU signal relays are general-purpose relays with a maximum switching power of up to 2 amperes.

The UB2-3SNU relays consist of two components: a coil and contacts. The relay coil is an electromagnet that is energized to actuate the contacts. The contacts are usually either normally-closed or normally-open, and can work in the following ways:

• Normally-closed: The contacts will remain closed until the coil is energized. When the coil is energized, the contacts open.
• Normally-open: The contacts will remain open until the coil is energized. When the coil is energized, the contacts close.

When the contacts are closed, they will allow an electric current to flow through the circuit. When the contacts are open, they will create an electrical barrier between the two sides of the circuit, thus preventing electric current from flowing. The UB2-3SNU relays are designed to operate between 24 and 48 volts AC and DC, and are capable of switching up to 2 amperes.

The working principle of the UB2-3SNU is simple. When the relay coil is not energized, the contacts remain in their normally-open or normally-closed positions. When the coil is energized, the electromagnet inside the coil creates a magnetic field, which attracts the contacts and causes them to change positions. Once the contacts open or close, they will remain in that position until the coil is de-energized.

In addition to providing general switching capabilities, the UB2-3SNU relays can also be used for voltage isolation, noise suppression, motor control, and other applications where silence, endurance, and performance are important factors. They are also ideal for applications in areas where high reliability, minimal energy consumption, and low operational cost are critical. With their ability to handle high amperage switching, the UB2-3SNU relays are perfect for use in industries including telecommunications, security systems, instrumentation, automotive, and HVAC.

The UB2-3SNU relays are reliable and easy to use. They are available in various shapes and sizes, and can be installed in either a vertical or horizontal position. They are also designed to operate in ambient temperatures as low as -55°C and as high as 125°C. Furthermore, the UB2-3SNU relays are RoHS compliant, meaning that they are safe to use in sensitive environments.

The UB2-3SNU signal relays offer reliable performance for applications that require up to 2 amperes of switching power. With their easy installation, high-temperature operation, robust design, and low-cost operational requirements, the UB2-3SNU relays are perfect for many different applications.
