There are three types of PLC timers:
- ON delay timer (TON)
- OFF delay timer (TOFF)
- Retentive Timer (RTO)
What is the name of the timer with sand in it?
hourglass, an early device for measuring intervals of time. It is also known as a sandglass or a log glass when used in conjunction with the common log for ascertaining the speed of a ship.
What is a mechanical timer?
Mechanical timers are used to actuate devices at the end of a specified time period. They do not require electrical power and can be stored for long periods of time.
How old is the hourglass?
The hourglass first appeared in Europe in the eighth century, and may have been made by Luitprand, a monk at the cathedral in Chartres, France. By the early fourteenth century, the sand glass was used commonly in Italy. It appears to have been widely used throughout Western Europe from that time through 1500.
How do you set a mechanical timer?
Quote from the video:
Quote from Youtube video: Around the dial push down all the pins within the time frame for your desired schedule. Use a pencil or pen if necessary. For example push down the pins aligned with 6:00 p.m. and 11 p.m. as.
What is an outlet timer?
A plug timer is a great way to control your lights, lamps, fans, holiday decorations, and more without having to worry about turning them on and off manually.
How does a digital timer work?
The working principle of the digital timer is, it uses the power source and different electronic components for a time like hours, minutes and seconds. The power source of this timer is either a battery otherwise a power cable connection or the clock gearing controlled by the counter.
What is a segment timer?
The 24 Hour Segment Timer is a high quality timer which can be used to switch lights and electrical appliances (up to 3200W) on/off automatically. It works by manually setting 15 minute segments to an on/off position with the option to choose up to 96 segments on or off in a 24 hour period.
What are the two basic classifications of timers?
Timers can be classified as on-delay or off-delay.
How does a mechanical timer switch work?
Turning the timer compresses a spring. As this spring unwinds, it turns gears, which in turn causes the dial on the timer to move. When the spring unwinds completely, the timer finishes it cycles. This triggers the sounding of the bell that occurs at the end of mechanical timer cycles.

What is microprocessor timer?
A timer is a specialized type of clock which is used to measure time intervals. A timer that counts from zero upwards for measuring time elapsed is often called a stopwatch. It is a device that counts down from a specified time interval and used to generate a time delay, for example, an hourglass is a timer.
What is timer microcontroller?
The timer is an important application in Embedded systems, it maintains the timing of an operation in sync with a system clock or an external clock. The timer has so many applications such as measure time generating delays, they can also be used for generating baud rates.
