Time Delay Relays - H2C-8-AC120-B Application Field and Working Principle

Time delay relays are an important part of the automation industry, as they are able to provide reliable time based control of a variety of machines and processes. The H2C-8-AC120-B is one such time delay relay, specially designed for use in residential, commercial, and industrial applications. This article will provide an overview of the application field and working principle of the H2C-8-AC120-B time delay relay.The H2C-8-AC120-B is a rugged, general-purpose time delay relay capable of measuring an input voltage and controlling an output voltage over a specified period of time. This time relay offers a wide variety of time ranges, including 0.1 sec - 18 hr, 0.1 - 60 min, and 0.1 sec - 5 min. It can be easily programmed through a built-in LCD display and provides simple graphical menu-based instructions. The H2C-8-AC120-B’s built-in digital timer also makes it easy to set and read back the time setting.The H2C-8-AC120-B time delay relay is designed for a variety of different applications, such as controlling lighting, motors, pumps, and door openers. It can also be used to control the timing of industrial process equipment, including presses, conveyors, and vacuum systems. The wide range of time settings makes it easy to control the timing of a variety of different devices, from high speed mechanical actuators to slow piezo transducers.The H2C-8-AC120-B time delay relay is typically wired to the control panel of the device it will be controlling. The most common type of connection is a 3-wire control circuit, in which a hot input voltage is connected to the first pin of the relay, followed by a neutral wire, and a third wire for the output. The output voltage can be programmed to a certain value, and the timer adjusted to meet the desired duration of the output voltage.The working principle of the H2C-8-AC120-B time delay relay involves the use of a bimetallic strip, which acts as a switch. The strip is heated by the current flowing through it and then begins to bend in response to the heat of the current. This movement of the bimetallic strip is used to mechanically open and close the output relay. As the current flows through the bimetallic strip, it alternates between open and closed positions, thereby creating the time delay.The H2C-8-AC120-B time delay relay is an essential component in the automation industry due to its reliable time based control abilities. The wide range of different time ranges it can provide, combined with its user friendly programming and easy installation make it an ideal choice for a variety of different applications. By understanding the application field and working principle of the H2C-8-AC120-B time delay relay, engineers and technicians can effectively utilize the advantages of this device in their projects.
