Time Delay Relays

Time Delay relays are a type of electrical switch which uses an activation time for controlling an electrical control circuit in a pre-determined time sequence. The H3YN-21 DC100-110 is a type of time-delay relay which accurately delays the activation and deactivation of a control circuit for a specific length of time.

Application fields

The H3YN-21 DC100-110 time-delay relay is suitable for a variety of applications. It can be used as a time counting and operating device for controlling air-conditioners, lighting systems, pumps, electric doors, elevators, and other electrical systems. It is also suitable for various temperature and humidity control systems as well as industrial ovens and cooling systems. It can also be used for reverse switching and either open-loop or closed-loop control. This makes it an ideal choice for controlling the electrical circuits of industrial production equipment.

Working Principle

The H3YN-21 DC100-110 operates on the principle of time-delay control. It contains a timer which is set to activate or deactivate the control circuit for a pre-determined length of time. When the circuit is turned on, a timer starts which is set for a fixed time. When the time is up, the timer triggers a relay which activates the output switch and closes the circuit. This energizes the controlled circuit and causes the load to activate. When the timer has expired, the output switch opens and the load deactivates and the cycle starts again.The H3YN-21 DC100-110 time-delay relay provides accurate timing of control circuit activation and deactivation and offers more control over the timing of equipment operation compared to other timing devices. It also offers a wide range of functions such as start delay, end delay, pulse control, pulse width adjustment, cycle control, time adjustment, and alarm control. The H3YN-21 DC100-110 is also relatively easy to set up and provides a variety of time settings. This makes it an ideal choice for controlling a variety of equipment in industrial and other applications.
