Time Delay Relays are control devices that are designed to automatically delay an action when a switch closes or opens.

The SC3120A Time Delay Relay is designed to be used in a wide range of commercial and industrial applications requiring timed switching operations. This relay offers excellent precision, reliability, flexibility, and easy operation. It is an ideal device for applications requiring precise timing functions, such as automotive machines, machine tools, process controllers, and alarm systems. In addition, its ability to be controlled over a wide range of voltages makes it especially useful for universal automated control systems.

The SC3120A Time Delay Relay is composed of four main parts: a relay module, a voltage converter, a time display, and a control switch. The relay module controls the electrical current associated with the relay. The voltage converter converts external AC current into DC power, and is used to provide power to the other parts of the device. The time display is used to indicate the amount of time that has elapsed since the relay was activated, while the control switch is used to set the desired delay time.

The working principle of the SC3120A Time Delay Relay is relatively simple. When the input is applied to the relay, it is energized and a time count begins. When the time delay reaches its set point, the output is activated. The output can be either normally open or normally closed based on the relay design. In both cases, the contacts and the relay coil remain energized until the power is removed.

This relay is typically used to turn a load on or off. It is extremely useful when the input power needs to be temporarily interrupted but the output needs to remain unchanged for a set period of time. It can also be used to repeatedly switch the load on and off in a cyclic fashion. For instance, a periodical timer used to run the wipers of a car.

The SC3120A Time Delay Relay is a high-performance and reliable device for applications requiring precise timing functions. It is commonly used in a variety of industrial, commercial and consumer applications, such as automotive machines, machine tools, process controllers, and alarm systems. With its flexible programming options and precision control, this is a great choice for producers and developers looking for a reliable and effective time delay relay.
