Time Delay Relays

Time Delay Relays are one of the most important components in automation systems. They are used for providing a time delay between two parts of a circuit or for controlling the length of an automated timing cycle. One of the most popular types of Time Delay Relays is the 7012PKL, which is used in a variety of industrial applications.

7012PKL Application Field

The 7012PKL is a programmable time-delay relay designed to be used in a wide range of industrial applications, including automation systems. Its versatile design allows it to be used in a variety of ways. It can be used as a simple timer with basic on/off functionality, allowing for delays of up to 99 minutes. It can also be used as a cycle timer that will periodically reset and start a new cycle. It can also be used as a relay switch, allowing for multiple outputs and inputs. It is also capable of being used as an alarm clock, a watchdog timer, or a timer with a multiple set of functions, which allow for further customization.

7012PKL Working Principle

The 7012PKL time-delay relay operates on the principle of a capacitor being charged by a current source. When the capacitor is fully charged, a signal is sent to start the time delay. The relay then uses the current from the capacitor to start the time delay cycle. The time delay is determined by the resistance of the capacitor and the current that is supplied to it from the current source. The time delay can be changed by adjusting the resistance of the capacitor or the voltage supplied to the capacitor.

When the time delay is complete, the relay sends a signal to turn off the current source, which then turns off the capacitor and the time delay is over. This cycle can be repeated over and over again, allowing for a variety of automation applications. The 7012PKL can be set for different time delays depending on the application and can be easily programmed using the onboard programming control.

The 7012PKL has been designed to work in hazardous environments such as explosive atmospheres and it is also resistant to shock, vibrations, and extreme temperatures. It is a reliable and durable time-delay relay, making it perfect for industrial applications.

The 7012PKL has become a popular choice for industrial automation due to its versatility and reliability. It is an ideal choice for controlling the length of timing cycles and for providing a time delay between two parts of a circuit. The 7012PKL is a reliable and durable time-delay relay, making it perfect for a wide range of industrial applications.
