Understanding Timers in Circuits

Introduction to Timers

• The session introduces two types of timers: "timer on the light" (temporizador a la conexión) and "timer off the light" (temporizador a la desconexión).

• A brief explanation is provided about how these timers function similarly to relays, utilizing coils that activate switches.

Functionality of Timer On the Light

• The timer operates by energizing a coil, which then closes normally open contacts after a preset time.

• Demonstration begins with setting up the first timer (T1), showing its symbol and functionality as it activates upon pressing a button.

• The timer can be programmed for different durations; for example, it can count down from 10 seconds or modified to 6 seconds.

Operation of Timer Off the Light

• This timer maintains closed contacts while energized and opens them once the countdown completes.

• It emphasizes that if connected to normally closed contacts, they will open when the countdown finishes.

• The operation is explained further: this timer starts counting only after disconnecting power from its coil.

Practical Applications of Timers

• Timers have numerous industrial applications, such as motor startups. In pneumatic systems, specific symbols are used for these timers.

• Two types of timers are discussed: digital and analog. The focus is on an analog type being used in practical exercises.
