Logic Diagram Relay. Carefully build this circuit on a breadboard or other convenient medium. In a plc a digital microprocessor performs the logic functions traditionally provided by electromechanical relays with the programming for this microprocessor taking the form of a relay diagram also called a ladder logic diagram.
Function of push button in rlc. The relay diagram used electrical continuity to show a rung as electrically closed. Step 1 first we hold relay individually with push button it means using push button 1 we hold relay 1 and using push button 2 we hold relay 2.
Or and not ladder logic.
Function of push button in rlc. In ladder logic diagrams a normally open relay contact is drawn as a set of parallel lines almost like a non polarized capacitor in an electronic schematic diagram. The original intent of rll was to provide a way for the controller to solve logic sequences involving discrete signals.
