Relay A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid state relays. Relays are used where it is necessary to control a circuit by a separate low power signal, or where several circuits must be controlled by one signal. What Is a Control Relay? Types of Relays Control relays were invented more than a century ago, and today's world of electronics is dependent on control relays to control the currents that power so many of modern society's electric and electronic gadgets. Control relays are electronic parts that are used in motors, power plants, power supply systems, transistors, and more. What Is a Control Relay? (with picture) wisegeek The master control relay is used in safety devices that will ultimately remove power from the load. Cutting and heavy pressing devices, for example, may need a master control relay to stop the device from causing injury to personnel. These master control devices will safely shut down the equipment. The Basics of Control Relays | Electrical Construction ... A relay is used to energize the starter, which, in turn, switches the motor voltage while the PLC controls the relay. Wired to provide a control sequence, relays may also be used for simple control schemes where a PLC would prove uneconomical. Troubleshooting relays can be handled in short order, without having to return to the maintenance shop for the computer necessary to analyze the control sequence within the PLC. DC motor direction control using relay circuit Which makes the ground or negative across the motor terminals, that is the same polarity on both sides. Similarly, when both switches are closed (here both terminals will have positive voltage) the same polarity will obtain at two sides. On both conditions, the motor terminals are shorted and the motor brakes. Relay Switch Circuit and Relay Switching CircuitBasic ... The advantage of relays is that it takes a relatively small amount of power to operate the relay coil, but the relay itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power. What is the function of a relay? Quora Relay is a switch which controls circuits electronically or electromechanically. The main function of this device is to switch on or off contact with the help of a signal without any human involvement.
