Time Delay Relays are components that provide a predefined operating time before a switch is initiated. This type of control allows for a wide range of circuit applications, from controlling the timing of automatic processes to switching on machinery in a sequence. The 7022NC is a specific type of Time Delay Relay developed by the company Chiyu Technology Co. Ltd. to meet a variety of time delay control requirements.

Overview

The 7022NC is well suited for controlling many different types of operations and industrial equipment. It is a compact electro-magnetic Time Delay Relay that features adjustable time delay ranges from 0.1 to 60 seconds. Its operating voltage is 12V DC and its output is a changeover contact type that can handle a maximum of 0.5A (at 24V DC). What makes the 7022NC particularly useful for industrial applications is its ability to provide reliable time delay setting due to its shock-proof and vibration-resistant design.

Application Field

Time Delay Relays are used in industrial automation to provide a connection between an input signal and a set of timed outputs. The 7022NC is no exception, and it is typically used for controlling processes with a reliable timing accuracy. Because it is reliable and flexible, the 7022NC is widely used within industrial, automotive, electrical and other commercial applications. For instance, it can be used to switch off electronic devices after a certain time interval has been reached, or to delay the opening of a valve in order to regulate water flow. In the automotive sector, the 7022NC is commonly used for controlling the timing of window motors, vehicle lighting, and other automotive operations that require accurate time delay control.

Working Principle

At the heart of the 7022NC is an electronic timing circuit consisting of a relay switch, a timer, a transformer, and a power supply. When the power is turned on, the timer is activated and the timing cycle begins. The relay switch is then engaged and the power supply feeds DC voltage to the transformer. The transformer induces a magnetic field which triggers the timer to start the timing cycle. As the timer reaches the time set by the user, it triggered the relay switch, and thus the output signal is sent.

Electromagnetic Time Delay Relays such as the 7022NC are suitable for applications that require reliable time delay control. This device is compact, reliable and vibration-resistant, making it suitable for all kinds of industrial and commercial applications. Additionally, its adjustable time delay timing range of 0.1 to 60 seconds makes it suitable for a wide range of applications.
