SAS3S220AD Industrial Controls

Time Delay Relays (TDRs) are a key component of any industrial automation system. The SAS3S220AD is an example of a TDR that provides a wide range of application possibilities. This article details the application field and working principle of the SAS3S220AD, and explains how it fits into the family of TDRs.

The SAS3S220AD is a multi-purpose TDR with a wide application field. It can be used for timing, periodic control, progress control, and start and stop control depending on the type of input, while its output can be used to control electrical loads such as contactors, solenoids, relays, and valves. The SAS3S220AD has a wide range of inputs and outputs, allowing it to be used for a variety of applications. The output power of the SAS3S220AD is rated up to 10A/50V AC, and it can handle up to 6A/50V DC inputs.

The SAS3S220AD has two operating modes: manual and automatic. In manual mode, the user can operate the device by pressing a pushbutton, which turns the relay on or off. In automatic mode, the device operates according to a preset time cycle. This is an ideal way to control electrical loads on a specific time schedule. The SAS3S220AD also features a timing accuracy of 0.1% and a cycle of as low as 0.1 sec.

The SAS3S220AD works on a two-step time delay principle. When power is first applied to the device, the internal relay is off. When the device\'s preset time has elapsed, the internal relay is turned on and the device begins to transfer energy to the output. After the preset time has elapsed again, the relay is switched off and the device returns to its initial state. This process continues as long as power is applied to the device.

The SAS3S220AD includes a built-in LED display to indicate the current status of the device. The LED will display green when the relay is off, and will display red when the relay is on. This LED display is integral to the setup of the device, as it allows the user to easily monitor the operation of the device.

The SAS3S220AD is a versatile time delay relay that can be used for a variety of applications. Its wide range of inputs and outputs, as well as its built-in LED display, make it an ideal choice for industrial automation systems. The device\'s two-step time delay principle helps ensure that the device operates accurately and efficiently, making it a reliable and effective component of any industrial automation system.
