Power Relays, Over 2 Amps: RH2B-UDC12V Application Field and Working Principle

The RH2B-UDC12V power relay is a device designed to control different types of electrical current, up to two amps. It is primarily used to switch on and off various components of a circuit, such as motors, lights, solenoids, and other electrical equipment. This power relay is suited for a wide range of applications, including industrial, heavy-duty, and residential. It can be used as a fail-safe device or a controller for various complex electric automation systems.

The RH2B-UDC12V takes advantage of electromagnetic force to coordinate the flow of electricity. Its construction features a coil that winds around a metal cylinder. When electric current is applied to the winding\'s leads, an electromagnet forms and pulls the armature lever into contact with a set of contacts. This completes or opens the circuit in a designated direction, depending on the specific method of wiring and configuration. The current is then guided through a designated path to create a circuit of specific output.

The RH2B-UDC12V power relay can be mounted in either a mold case or a plug-in printed circuit board (PCB) version. The solid core version consists of a single unit cube with LEDs for visual inspection. The plug-in version offers various accessories to customize the design for a specific application. The superior temperature characteristics and regulated power input makes it ideal for temperatures of up to 50°C. In addition, the RH2B-UDC12V was designed to classify and match highly reliable power requirements in energy plants, motor control, and even in automotive. Its superior insulation withstanding voltage characteristics ensures a great working performance in all covered applications.

The RH2B-UDC12V offers two options for coil voltage: 5 volts direct current (DC) and 12 volts direct current (DC). When supplying the coil with 5 volts DC, the contacts can open and close when proper voltage is present, as low as 2.4 volts DC. With the RL2B-UDC12V, the contacts can open and close down to 3.6 volts DC. The coil is designed to be operated on AC or DC power, making it suitable for both applications.

It is also possible to configure the relay as a normally open (N/O) or normally closed (N/C) relay. Normally open means that the circuit is open until current is applied to the coil, switching the contacts to a closed state. The normally closed option means that the circuit is closed until the coil is energized, switching the contacts to an open state.

The RH2B-UDC12V belongs to the family of power relays over two amps. It is designed with a number of features that include wide variations in motor torque and a series of continuously adjusting characteristics. This makes it suitable for a variety of applications, from industrial automation to residential and specialty systems. It is highly reliable, with a long life cycle and superior temperature characteristics, making it a dependable choice for many applications.
