Time Delay Relays

KRDM220 is a time delay relay which is widely used in various industrial applications. It is a timing device that allows simple and reliable, precise control of ac and dc loads. It is essentially a logic device that has a set time delay when triggered by an input voltage. The time delay can range from milliseconds up to several hours.

It consists of two main components, a timing element and a relay. The timing element consists of a clock and a counter. The clock is used to start the timer and the counter keeps track of the number of cycles that have occurred since the timer was started. The relay is used to control the associated load. When the timer has counted the right number of cycles, then the relay will switch the load on or off.

The KRDM220 can be used in various applications requiring a delay such as in motor control, process control, security, lighting control, and many other industrial applications. It is reliable, accurate, and easy to use. It is also quite flexible in that it can be set to turn on and off loads after a preset amount of time. It is also a safe and reliable way of executing complex operations through one simple control.

The working principle of the KRDM220 is quite simple. An input signal, usually an electrical pulse indicating the presence of an “on” signal, is sent to the timing element. The clock starts counting, and each time it does, the counter is incremented by one. When the counter reaches the selected value, the relay is switched “on”, and the load is turned on. This process is then repeated until the load is turned off.

The KRDM220 is an ideal device for various industrial applications requiring a timed delay. It is a reliable and accurate device that is easy to use and set up. Its flexibility makes it very useful for complex tasks, such as motor control and lighting control. In addition, the KRDM220 is a safe and efficient way of controlling loads. It is a reliable device that can be used in many industrial applications requiring precise timing.
