As the coil is energized, the normally open set of contacts are closed and the normally closed are opened. It's important to know the terminology as well as the difference between the two. Furthermore, it's important to quickly determine the configuration of a specific relay and circuit based on the diagram on the front of a specific relay. The relay above features a 24VDC coil between A and B contacts. Note that a DC relay will have a polarity assigned to the terminals while an AC relay will not. In this case, the positive terminal is terminal A and the negative one is terminal B. The contacts are labeled from 1 to 9. By following the diagram, we can identify the contacts as follows: Normally Open 4 - 7 5 - 8 6 - 9 Normally Closed 1 - 7 2 - 8 3 - 9 A normally open contact will not conduct any electricity while the coil is de-energized. In other words, you may measure an infinite resistance across any of the terminals listed within the "Normally Open" list above while the relay coil is not powered. Once there's a current drawn by the coil and the relay is energized, the contacts will conduct current. The opposite is true about normally closed contacts. They will conduct current in the de-energized state and stop conducting when power is applied. Full Tutorial: https://solisplc.com/industrial-relay...
