WebA special class of electromechanical relays called time-delay relays provide delayed action, either upon power-up or power-down, and are commonly denoted in ladder logic diagrams by “TD” or “TR” designations near the coil symbols and arrows on the contact symbols. Here is an example of a time-delay relay contact used in a motor control ... WebSep 20, 2012 · An adjustable time delay relay is sometimes included in this control scheme to delay the restart and allow the material to be cleared from the crusher. The time delay may be included in the overcurrent relay or as a separate device. The same circuit could be used for other applications as well.
