Time Delay Relays are essential components for many electrical and electronic systems. As the name implies, these devices are designed to provide an adjustable time delay before switching a circuit. The 1472969-8 is a time delay relay from Omron Corporation. It is used in many applications to control the timing of the switching operations of the system. In this article, we will discuss the applications and working principles of the 1472969-8.

Applications of the 1472969-8

The 1472969-8 time delay relay is designed for applications that require precise timing control. Examples include switching operations for motor starters, lighting and other electrical systems. It can be used for control of safety circuits, fan coils, cooling motors and pumps, and other time-related operations. It is also suitable for controlling the electric circuit of home appliances.

Working Principle of the 1472969-8

The working principle of the 1472969-8 time delay relay is quite simple. The device consists of two main components: a time limit switch and an electromechanical relay. When the switch is turned on, the relay energizes, closing the circuit and allowing the device to be switched on. This energizing current is maintained until the preset time period elapses, at which point the relay de-energizes, opening the circuit and switching off the device.

The time delay setting of the relay is adjusted by a thumbwheel on the device. This thumbwheel controls the time delay for the relay, allowing precise control of when the switch is opened or closed. The time delay is usually set to a fraction of a second, a few seconds, several minutes, or even hours.

The 1472969-8 time delay relay also has a number of safety features, such as a built-in power-failure backup system, an overload protection system, an under-voltage protection system, and a moisture-resistant seal. These features make the device suitable for use in difficult environments, such as industrial and maritime locations.

Conclusion

The 1472969-8 is a time delay relay from Omron Corporation. It is designed for applications that require precise timing control, such as switching operations for motor starters, lighting and other electrical systems.
