The 20-109-0120, also known as the Electronic Time Delay Spot Relay, is a versatile electronic timer that can be used for a variety of application fields. This device is capable of providing timing for a variety of tasks, including alarms, outputs, sensor debounce, and more. With this device, users can create a multitude of unique timing functions, all with varying degrees of complexity. Due to its long service life, it can be expected to last for many years. In this article, we will discuss the application field and the working principle of the 20-109-0120.

Application Field: The 20-109-0120 is commonly used in applications that require the need for accurate and reliable timing. It can be used for applications such as access control, remote sensing, industrial automation, and voltage monitoring. Additionally, this timer is also useful for applications such as monitoring the air in an enclosed area, controlling gas output, and controlling the temperature of an environment. In addition to these basic tasks, this timer can also be used as a reliable alarm system, capable of alerting users when a specific time period has been reached.

Working Principle: The 20-109-0120 uses a combination of electrical and electronic components to provide accurate timing. The electrical portion of this device is composed of a solenoid valve, a power transformer, and a relay contactor. The solenoid valve is used to control the flow of gas. The transformer is then used to covert the alternating current from the solenoid valve into a direct current. The current from the transformer is then used to power the relay contactor. The contactor is capable of switching the relay on or off at pre-programmed times. Once the relay\'s timer has expired, the contactor will turn off the relay and reset the timer.

The electronic side of the 20-109-0120 is composed of a quartz oscillator, a microcontroller, a memory module, and a display unit. The quartz oscillator is used to generate a clock signal which is used to time the various components of the device. The frequency of the oscillator can be adjusted to accommodate different time ranges and resolutions. The microcontroller is used to receive the signal from the quartz oscillator and then parse it into a countable data format. The microcontroller then stores this data in the memory module and the display unit will display it. The microcontroller can also be used to control the relay contactor, allowing users to set their desired times for the relay to stay on or off.

The 20-109-0120 is a powerful and versatile electronic timer that can be used in a multitude of applications. Its simple design makes it easy to use and maintain, while its long service life ensures that it will remain reliable for many years to come. With the 20-109-0120, users can create unique, accurate, and reliable timing sequences that can be used for a range of applications.
