Power Relays, Over 2 Amps: RH2B-UTDC12V Application Field and Working Principle

The RH2B-UTDC12V is a high-current power relay designed for switching high torque loads and providing reliable protection to circuits. Applications of the RH2B-UTDC12V include commercial and industrial control systems, fast switch cycles for electric motors and automotive control systems.The RH2B-UTDC12V is a sealed power relay with a contact rating of 30 amps at 250VAC and a contact load up to 100 amps at 30VAC. It has an operating temperature range of -40°C to +85°C and can handle enormous switching power of up to 10,000VA. The relay features reliable contacts with excellent performance and long life despite multiple switching over time. The seal design protects it from dirt, oil, grime, and other contaminants.The RH2B-UTDC12V is a single-pole double-throw (SPDT) power relay with two contact forms for switch normally open (NO) and normally closed (NC). This type of contact arrangement allows for the control and connection of two different circuit branches. When in the normal open position, the circuit is open, and when the relay receives an input signal, it closes the circuit, thus switching the power to the load. When the input signal is removed, the relay reverts back to its normal open state.The RH2B-UTDC12V works on the principle of an electromagnetic field which is generated by passing an electric current through a coil. This electromagnetic field creates a movement of an armature which pulls the contact from the normally-open (NO) form to the normally-closed (NC) form where it makes contact and thus completes the circuit. This type of control design is known as "make-before-break" because the contacts are making contact before breaking the other set of contacts.The RH2B-UTDC12V is designed to operate from a DC power supply with a maximum rating of 12V. It is available in a variety of coil voltages which allows for flexibility in the selection of input voltage. This power relay is suitable for applications in harsh environments with its corrosion-resistant steel body, gold-plated contacts, and compact size. The RH2B-UTDC12V also has a wide range of control options available to meet various application requirements. It can be configured with a 1-form-1- and 1-form-2- throw operation, and it also comes with a control LED so that the user can easily tell when the relay is receiving an input signal.In summary, the RH2B-UTDC12V is a high-current power relay designed for switching high torque loads and providing reliable protection to circuits. Its SPDT contact form, high current rating, and wide operating temperature range make it a versatile choice for a variety of applications. The company also offers a wide range of control options and additional features to further customize the device as per user requirements.
