Time Delay Relays have been around for decades, playing a key role in countless applications. The QDS45S220A is a widely used time delay relay unit, designed for industrial and commercial electrical applications. This article will explain the application field and working principle of the QDS45S220A.

The QDS45S220A primarily finds application in areas where precise timing or sequencing is needed. Many machines have components that need to move in a certain order and precise timing is often required for this to occur correctly. For example, a conveyor system may need to move its products from one place to another within the required time. The QDS45S220A can be used to control the time delay and make sure each step of the process is completed in the right sequence. Additionally, the QDS45S220A can also be used as an overload device to prevent the system from overloading in case of a power surge.

The QDS45S220A features an adjustable time delay range of between 2-120 seconds. This allows for a broad range of applications. The QDS45S220A also includes a selectable relay output which permits different outputs for different reasons. For example, the relay output could provide an output for two different functions; a signal to reduce power to a motor or a signal to start the motor. In addition, the unit can be easily programmed using the user-friendly graphical interface.

Regarding the working principle, the QDS45S220A works in a similar way to other time delay relays. The device is supplied with a 0-10V DC input voltage and when this reaches the pre-set time delay value, the relay output would be activated. Inside the QDS45S220A is a timer, which is responsible for adjusting the timing according to the pre-set value. In addition to this, the unit also features a current transformer which prevents power surges.

The QDS45S220A is designed specifically for a wide variety of time-dependent applications. From providing precise timing and sequencing to protecting against power surges, the QDS45S220A is the perfect tool for industrial and commercial electrical applications.
