Time Delay Relays

Time Delay Relays, commonly known as TDRs, are a type of electronic control element that provides a simple and cost-effective solution to a wide range of applications. They are used in a variety of applications, from industrial automation, to medical, electrical and other types of applications. This article will explain the use and application fields of the CHB-38-70011 time delay relay and its working principle.

Application Field

The CHB-38-70011 time delay relay has a wide range of applications, from industrial automation to medical, electrical and other types of applications. It can be used in a variety of situations, such as power and industrial-level automation, machine control, medical attention, testing and other applications. Some examples include: machine control, conveyor systems, automated assembly machines, surface mount and leadframe machines, medical devices, hydraulic systems, motor speed control, emergency alarms and signal delay applications. With its adjustable time delay settings, it can be used to delay a range of operations, such as warning signals, pulse transmission or start/stop sequencing.

Working Principle

The working principle of the CHB-38-70011 time delay relay is fairly straightforward. It uses a timing circuit to measure a defined time interval. This interval can be adjusted using the adjustable time delay settings on the relay. When the preset time has elapsed, the relay will then be activated or deactivated depending on the application.

In terms of its components, the CHB-38-70011 time delay relay contains a timing circuit, an adjustable potentiometer (for adjusting the time delay settings) and a power supply. The timer circuit contains a capacitor and an RC circuit (resistor-capacitor network). The capacitor is connected to the power supply, and its capacitance is varied through the adjustable potentiometer. When the power supply is connected, the capacitor will begin to charge, and its voltage will increase to a certain value over a specific time period. When this voltage is reached, the timing circuit will create a signal, and the relay will be activated or deactivated depending on the application.

The CHB-38-70011 time delay relay also has a built-in safety feature. It will deactivate automatically if the power supply is removed. This ensures that the relay is not overused and protects any connected equipment from potential damage.

Conclusion

The CHB-38-70011 time delay relay is an easy-to-use and cost-effective solution for a variety of applications. With its adjustable time delay settings, it can be used to delay operations and protect equipment from potential damage. The working principle of the CHB-38-70011 time delay relay is fairly straightforward and should be easy to understand.
