DJR2220A Time Delay Relays are used for a wide variety of applications, including circuit protection and flow control, alarm systems, and electrical control systems. They are designed to provide automatic control by timing the on and off times of an electric circuit. The DJR2220A time delay relay is a delay-on relay which opens the circuit when power is applied and closes it after a specified period of time.The DJR2220A time delay relay is composed of two basic parts: a switching contact assembly and an adjustable timer. The switching contact assembly is a two-pole, normally-open relay that switches the circuit on and off. The adjustable timer controls the amount of time that the relay remains open after power is applied.The DJR 2220A time delay relay can be programmed for either a fixed delay time or an adjustable delay time. When programmed for a fixed delay time, the relay will remain open for a fixed amount of time after power is applied, regardless of the time of day or external events. When programmed for an adjustable delay time, the length of delay is determined by an adjustable potentiometer. This allows for greater control over the timing of the circuit\'s on and off times.The DJR2220A time delay relay also has a built-in memory function that allows for the programmed timing to be retained even when power is interrupted. This is an especially useful feature when on and off times must remain consistent even during power outages.The DJR2220A time delay relay is designed to be simple and reliable, and it can be used in a wide variety of applications. It is commonly used in alarm systems, water pumps, timers, and other electrical control systems. It can also be used for circuit protection, flow control, and many other applications.The DJR2220A time delay relay is designed for a wide range of input voltage, from 12 VDC to 24 VDC. It also operates at temperatures ranging from -40°F to +185°F, making it suitable for use in many different industries and applications.The DJR2220A time delay relay is an ideal solution for applications that require accurate, reliable timing. Its simple design and adjustable timer make it easy to use and extremely versatile. It is a dependable choice for many different applications, from circuit protection to flow control.
