Time Delay Relays

Time delay relays are used in circuits to allow a designated period of time to elapse before an operation is performed, thus preventing false triggering and allowing time for the actuator to move into position, for example. Depending on the requirements, these relays can be programmed with a delay range from milliseconds to hours. Of the many types of time delay relays available, the H3YN-4 AC100-120 offers an accurate and cost-effective solution for applications requiring precise control.

Application Field

The H3YN-4 AC100-120 relay is most commonly used in automation control, maintenance, and other industrial fields. The product can be used in various situations such as controlling or timing the operation of motors, conveyors, automatic doors, PLC inputs, or HVAC control systems. The relay can also be used with logic operations such as counters, logic circuits, and timers. It can even be used for time-based cooling systems where a certain temperature must be maintained within a limited period of time.

Working Principle

The H3YN-4 AC100-120 is a solid-state time-delay relay with a wide range of 100ms - 120s. It is powered by AC100V, and is equipped with three selectable time ranges (delay ON/OFF delay and Cycle). When triggered by an input signal, the H3YN-4 AC100-120 has an adjustable output time depending on the selected range. The output time is adjustable from 0.3-10 seconds in the delay ON range, 0.3-120 seconds in the delay OFF range, and 3-600 seconds in the Cycle range. The H3YN-4 AC100-120 is also a high voltage collapse relay, offering additional protection against contact damage caused by a power surge. It has a built-in voltage suppression circuit that helps to protect circuit boards and other components from overvoltage transients. In addition, it has an LED warning indicator that lights up when the input exceeds the rated voltage and current.

Conclusion

The H3YN-4 AC100-120 time delay relay is a reliable and economical solution for precise control in many types of automation applications. It is well suited for a wide variety of tasks including motor and door control, logic operations, timer circuits, and high voltage surge protection. With adjustable output timing ranging from 0.3-600 seconds, the H3YN-4 AC100-120 offers an ideal and cost-effective alternative for situations requiring time delay.
