when dealing with time delay relays we have two kinds there are the on delay and the off delay this video will focus mostly on the on delay principles and how they can be used in sequence control for motor control now an on delay relay is like any other relay it will have a coil and it will have a set of contacts now the difference is not only does it have a set of instantaneous contacts so here I have a normally open set of contacts a normally closed set of contacts and what I mean by instantaneous is when this relay or coil energizes these contacts will close instantly and these contacts will open instantly the difference is these contacts here I have a normally open time to close and I have a normally closed time to open so let's take a look at exactly how that plays out so I've pushed a button I've energized this coil this tdr time delay relay and it's got its timing up five seconds
