Time Delay Relay - Function and how to use it
Understanding the differences between various time delay relay operations might be a bit confusing. This simple overview about the three most used time relay should make it easier to visualize what’s happening during the timer operation.
Overview time relays
On Delay time relay (TON)
- The contacts swítch after a predefined time.
- The relay coil must be energized until the switching time.
Off Delay time relay (TOF)
- The contacts swítch immediately when the coil is energized
- You return to the initial position after a preset time or when the coil is deactivated
