Time Delay Relays are widely used in industrial automation, e.g. for controlling lights, fans, motors. They provide time-based control such as timer mode or cycle mode. H3JA-8C AC100-120 30M time delay relay is also a kind of useful releay for industrial applications.

Application Field of H3JA-8C AC100-120 30M Time Delay Relay

The H3JA-8C AC100-120 30M time delay relay is mainly applied to farmland irrigation, electric heating and other industrial processes. It can be used to control the opening and closing of all kinds of power circuits, water supply, drainage, electric doors and windows, charging and discharging of capacitor banks, etc. In short, the H3JA-8C AC100-120 30M time delay relay can be used in any location where a time delay is required.

Working Principle of H3JA-8C AC100-120 30M Time Delay Relay

The working principle of H3JA-8C AC100-120 30M time delay relay is based on the set value of the real time and preset accurate timing delay time accomplishing through the AC100-120V input supply. The timer begins to run after switching on and the time delay is related to the external time signal. The timer can be configured with either time delay or cycle time delay. The time delay of this relay can be set by adjusting the adjuster and the time range is 0 to 30 minutes.

When the timer works as a time delay mode, the output will be on for the preset time then it will deactivated until next cycle. This mode is used for illumination control, ventilation control and other timing control uses. The time delay range can be adjusted via the potentiometer and the minimum adjust time is 0.1 second. For instance, when the unit is set to 3 minutes, the output will remain OFF for 3 minutes, then it can be set to remain ON for 3 minutes.

As for the cycle mode, the output can be on or off for the given cycle time. This mode is mainly used for controlling the opening and closing of dust collectors. The timing range of this cycle mode can be adjusted via the potentiometer. It can range from 1 sec to 30 minutes.

The H3JA-8C AC100-120 30M time delay relay offers a variety of features such as insulation and oxidation resistance capabilities. It also has a highly efficient thermal protection design, which makes it highly reliable and safe for use in industrial settings. Furthermore, the H3JA-8C AC100-120 30M time delay relay has an impressive contact life of more than 5000 times making it suitable for a wide range of applications.

In conclusion, the H3JA-8C AC100-120 30M time delay relay is a useful device for controlling the opening and closing of electrical circuits. It can be used in a variety of industrial applications due to its unique features such as insulation, oxidation resistance, and long contact life. Furthermore, this relay offers adjustable time delay range and cycle time, which makes it suitable for a variety of applications.
