Time Delay Relays

Time Delay Relays are devices that hold a load activated for a set period of time, and then turn it off. They play a critical role in the automation and energy efficiency of industrial and commercial applications, from running manufacturing and machinery processes to powering ventilation and air conditioning systems. The H3JA-8A 200-240VAC 60M is a particular type of time-delay relay, designed to provide reliable performance in industrial and commercial settings.

Application Field

The H3JA-8A 200-240VAC 60M is a versatile Time Delay Relay (TDR) used for various types of commercial and industrial applications. It has a built-in power source supply that can provide up to 60mA of current to drive the load. Additionally, the relay has an adjustable time range from 0-60 seconds, and is programmable through a variety of methods, such as jumper settings, rotary switches, and more.The H3JA-8A 200-240VAC 60M is versatile enough to perform in a number of application areas, from security and fire control to machinery control and process automation. In security and fire control systems, the TDR may be used to control exit/entry access, or to control door locks and lighting systems. In machinery control applications, the TDR may be used to control pumps, motors, and other mechanical processes. Finally, in process automation, the TDR can be used to monitor and control flow rates, temperatures, and pressure levels.

Working Principle

The working principle of the H3JA-8A 200-240VAC 60M is simple. When the input voltage is applied, the TDR will delay the activation of the load for the specified time period and then will turn off the load. During the delay period, the TDR will continuously monitor the voltage level and compare it to the specified set point. If the voltage level falls below the specified set point, the relay will turn off the load immediately.The H3JA-8A 200-240VAC 60M is constructed with two independent components: a timing circuit and a control circuit. The timing circuit is responsible for providing an accurate time delay before the relay switches on or off. The control circuit is responsible for monitoring the voltage level and comparing it to the pre-set set point. If the set point is reached, the relay will activate the control circuit and turn the load on or off.

Advantages of H3JA-8A 200-240VAC 60M

The H3JA-8A 200-240VAC 60M has a number of advantages that make it a reliable choice for commercial and industrial applications. The adjustable time range from 0-60 seconds allows users to control the amount of delay in the activation or deactivation of a load within a reasonable range. Additionally, the built-in power source supply is designed to provide up to 60mA of current, ensuring consistent energy flow to connected devices.The TDR is also manufactured with a variety of programming methods, such as jumper settings, rotary switches, and more. This makes it convenient for users to easily configure the relay according to their exact needs. Finally, the TDR is precision designed for consistent performance and long operational life.

Conclusion

The H3JA-8A 200-240VAC 60M is a versatile time-delay relay designed for various commercial and industrial applications. The relay is equipped with two independent circuits—a timing circuit and a control circuit—which provide increased control over the delay time and provide reliable performance for a long period of time. Additionally, the adjustable time range, built-in power source, and flexible programmability give users a range of options for controlling and managing a variety of applications. Ultimately, the H3JA-8A 200-240VAC 60M is designed to help users optimize their energy efficiency and their automation and control processes.
