Power Relays, Over 2 Amps - RT134012 Application Field and Working Principle Relays are common electro-mechanical components used for controlling electrical circuits. This is particularly true in the case of RT134012, a double-pole, double-throw (DPDT) power relay capable of switching flows of over 2 Amps. This type of relay is especially well-suited for controlling large, high-current circuits in a variety of applications, such as motor starters, DC motors, lighting systems, industrial automation systems and more.To explain the operation of RT134012, it is best to start by considering the most basic form of a relay: a single-pole, single throw (SPST) switch. A SPST switch is a device that has two terminals, a normally open (NO) connection and a normally closed (NC) connection. When the switch is open, the NO terminal is connected to the NC terminal. When the switch is closed, the NC terminal is disconnected from the NO terminal. RT134012 operates on the same principle; however, it is much more complex due to its two poles and two throws.Essentially, RT134012 is a double-pole, double-throw (DPDT) power relay. It has four contacts (A1, A2, B1, and B2), and each contact is either normally open or normally closed. The two poles are identical in that they control the same two switches at the same time, but each of the two poles can be switched independently. This control allows for a greater degree of circuit control than a single-pole, single-throw (SPST) switch.The primary application of RT134012 is for motor control on larger, powerful electrical circuits. For example, it can be used to start or stop a motor, reverse motor direction, or control motor speed. RT134012 also enables more complex functions such as on/off starting or controlled acceleration and deceleration.To understand how this relay operates, consider a motor controller circuit with two switches, one for each phase of the motor. In the controller circuit, when the switch for one phase is open, the switch for the other phase is closed. This connects the two phases together in order to start the motor. When the switch for the other phase is open, the switch for the first phase is opened and the motor is stopped.RT134012 is used in this circuit to perform the switching. The two poles of the power relay are connected to each of the two switches in the circuit, with one pole controlling the switch for one phase and the other pole controlling the switch for the other phase. When the normally open side of the first pole is connected to the normally closed side of the second pole, the circuit is closed and the motor is started. When the normally open side of the second pole is connected to the normally closed side of the first pole, the circuit is open and the motor is stopped.In essence, RT134012 is a highly reliable power relay that is capable of switching flows of over 2 Amps. It is a double-pole, double-throw (DPDT) switch, allowing more complex functions to be controlled, such as on/off starting and controlled acceleration and deceleration. It is well-suited for controlling larger, high-current circuits in a variety of application, such as motor starters, DC motors, lighting systems, and industrial automation systems.
