Relays are used when you need to switch higher currents than a switch can handle, or when you want to isolate an electrical circuit. What are the purpose of relay in the electrical system ... (2) Depending upon the Type of Application, relays are selected. (3) The Purpose of relay in Electrical system as follow below: Relays are utilized to protect electric power systems against trouble and power blackouts as well as to regulate and control the generation and distribution of power Relay Operation of a 12 A relay A simple electromagnetic relay consists of a coil of wire wrapped around a soft iron core (a solenoid), an iron yoke which provides a low reluctance path for magnetic flux, a movable iron armature, and one or more sets of contacts (there are two contacts in the relay pictured). 12 volt relays from Chicago Sensor A 12 volt relay is a switch powered by 12 volt electric current. Most relays, including the one we sell at Chicago Sensor, use an electromagnet to operate a switching mechanism. Relays are used to control a circuit using minimal current, even though the device they control may be powered by much stronger current. A relay may also be used when it's desirable to control multiple devices with one signal.
