Write a ladder logic program that will turn on a light if a no push button is pressed 8 times10/26/2023 ![]() When the start button is pushed it allows current to flow through the relay coil and forces the relay contact to become closed. There is one relay in the circuit consisting of both a relay coil and a relay contact. The stop button is normally closed and the start button is normally open. ![]() Both the start and stop switches are momentary which means they return to their normal state after you push them. It is one of the most common circuits used in machine control. ![]() Now that you understand the relay function let’s look at the way in which relays are typically drawn in relay logic.īelow is a seal circuit or a start/stop circuit. ![]() Before going forward, review how a relay works here.
