Time Delay Relays are ideal for controlling machines and other powered devices during specific events, as they allow the user to set a delay between when the event occurs and when the action for the machine or device is triggered. The H3M-H DC12 B is a multi-functional time delay relay, designed specifically to provide a highly accurate and reliable delay control over a wide range of applications. This article will explore the application field and working principle of the H3M-H DC12 B.

Application field

The H3M-H DC12 B is a widely used time delay relay, as it can be used in a wide range of applications, including industrial equipment controls, automotive and aerospace applications, mechanical controls, and many more. It is ideal for controlling machines, controlling pumps and fans, and for controlling other powered devices during specific events. It is specifically designed to provide highly accurate and reliable delay control over a wide range of applications. The H3M-H DC12 B is suitable for low- and high-voltage applications, with an AC power supply range of 85-265V and a DC power supply range of 12V. It also supports a range of operating temperatures from -40°C to +60°C.

Working principle

The H3M-H DC12 B works by sensing an input signal and then using an adjustable timer to delay the output of the signal. This is achieved by utilizing two sets of contacts; one set is designed to trigger the power supply to activate a timer and the other set is designed to activate the output signal after the timing period is complete. When the input signal is activated, the power supply is triggered and the timer begins counting down. When the timer reaches zero, the output signal is activated. The timer can be adjusted to the desired delay time, allowing the user to customize the time delay for different applications.

The H3M-H DC12 B also features an adjustable time range, with a minimum delay of 0.05 seconds and a maximum of 1000 hours. It also features an in-built power supply protection circuit, which prevents the relay from being damaged due to sudden spikes in voltage or current. Additionally, the H3M-H DC12 B is designed with an LED indicator to alert the user when the timer has reached its endpoint.

Conclusion

In conclusion, the H3M-H DC12 B time delay relay provides an ideal solution for controlling and delaying machines and other powered devices over a wide range of applications. It is designed for both low- and high-voltage applications, and supports a range of operating temperatures. It features an adjustable time range and adjustable timer, allowing the user to customize the delay time. Additionally, the H3M-H DC12 B is designed with an in-built power supply protection circuit and a LED indicator for added protection and convenience.
