Delay timers are used extensively particularly in industrial applications. Observe the following points:
* Some or all industrial control systems need timing operations.
* Timing devices are used to cut on or off pilot devices at a preset time.
* Time delay relays and solid-state timers are used to provide the desired delay and timing functions.
Adjust the timing resistors and capacitor to suit your desired timing requirements.
**Open the SPST switch to start the timed OFF delay process**
Green LED illuminates when relay is deactivated.
