Time Delay Relays: Application Field and Working Principle of H2F-DFC AC200/220/240

Time delay relays are a type of electrical switch that operates on a specific time transition. Relay delays provide an efficient option for controlling processes and ensuring a safe environment for users and equipment. The H2F-DFC AC200/220/240 series is a low-cost and reliable time delay relay designed for applications ranging from 1/8-2.5 seconds with optional adjustment range up to 30 seconds.The H2F-DFC AC200/220/240 series has built-in din-rail mounting clips, making it simple to install. It also features selectable time range and close circuit delay. The series is suited for applications such as flood protection systems, cooling tower control systems, or elevator access control systems. It has an operating temperature range from -30 to +55 degrees Celsius.The H2F-DFC AC200/220/240 time delay relay works by using a timer with a set hold time. When the power is supplied to the timer input, the timer will start counting down the preset time. When the time period is elapsed, the timer will turn on the output. This will trigger the next sequence in the process. If the power is removed, the timer will reset itself.The H2F-DFC AC200/220/240 series is also capable of adjustable time delay, meaning that it can be used for a wide range of applications and adjusted to any delay duration that is required. This adjustment can be done using the DIP switch located on the device itself.The device is also capable of delayed close, meaning that the output will turn off after the preset time. This capability is useful for applications that require an output to be switched off after a certain amount of time. The delayed close feature can be enabled by setting the DIP switch to the close duration position.In addition, the H2F-DFC AC200/220/240 time delay relay also has some safety features built-in. A built-in surge protector helps protect the unit from spikes in voltage or current, while a short circuit protection function prevents the device from being damaged in the event of a short circuit.The H2F-DFC AC200/220/240 series is a reliable and cost-effective solution for many different applications. It offers a wide range of benefits such as adjustable time delay, surge protection, and short circuit protection. It is an ideal choice for applications ranging from flood protection systems to elevator access control systems.
