A time delay relay is a type of relay that introduces a delay in the switching process. When it receives a trigger signal, it does not immediately perform the task. Instead, it waits for a set amount of time before executing the action, whether that is turning on or off a connected device. This delay can be in the form of a preset duration or an adjustable time period, depending on the specific relay model.

    How Does It Work?

    A Time Delay Relay typically works through an integrated timer circuit. When a trigger signal is applied, the relay begins counting down from the preset time delay. Once the countdown reaches zero, the relay performs its intended action, such as closing or opening a switch. The time delay is critical because it allows for a controlled sequence of operations, making sure that the devices in the system are activated or deactivated at the right time.
