This document explains each and everyrelay and its working principlewith appropriate figures. Only some of the relays are explained in this document for making it simple and understandable. Hope that you will get a good idea on this topic once you start reading this information. Furthermore, for...
Electromagnetic relay is the simplest, oldest and most widely used relay. Its basic components are coils, magnetic cores, armatures, springs and contacts. The magnetic system is used to convert the input current into the mechanical power required for contact closure. The contact system converts the...
thermal relays, power varied relays, multi-dimensional relays, and so on, with varied ratings, sizes, and applications. Classification or the types of relays depend on the function for which they are used.
Latching relays have two stable positions – ON and OFF – and maintain the last switching position. To change the state, an energy supply is needed. There are two advantages in using bistable relays: Zero power is consumed after switching, and the capacity of the relay to maintain its ...
When the excitation applied to the relay coil is equal to or greater than its action value, the armature is sucked into the guide magnet, and at the same time the armature presses the contact shrapnel, making the contact turn on, off or switch the circuit being controlled. When the relay...
Over the years IDEC has introduced many new innovations to its family of relays. Thanks to technological advances and creative engineering, our relays have continued to set a new standard as we strive to meet the needs of our customers. Global approvals and acceptance only prove how IDEC has ...
The main types of relays are latching relay, solid-state relay, automotive relay, overload protection relay, electromechanical relay, and others. A latching relay refers to a relay that retains its contact position after the control power has been removed. Latching relays enable a customer to con...
When the electromagnet is de-energized, it loses its magnetism, and the tension spring pulls the armature up to block the operating circuit. Function: Use low voltage to control high voltage; remote control; active control. Symbols of electromagnetic relay: (a) General symbol of coil; (b) ...
Within the broad type classification of relays many variations exist, each having its own specific application and hence its own particular parameters to be checked. Obviously in order to determine the important aspects of any test procedure, the use to which the device is to be put needs to ...
DPDT relays are some of the most common relay form types found in industry due to their versatility. Each Form-C contact set offers a choice of either normally-open or normally-closed contacts, and the two sets (two “poles”) are electrically isolated from each other so they may be used...
