Time Delay Relays

Time delay relays are devices that open or close an electrical circuit at an appointed time, or after a certain period has elapsed. A common function programmed into these relays is the ability to delay an energized circuit by a certain time interval. They are useful in a wide variety of applications, from machine timing and control to electric motors and switching circuits.

7022 ACT Application Field and Working Principle

The 7022ACT is a time delay relay made by the United States manufacturer, Opto Electronics, Inc. This specific product has many applications, including machine or equipment control, lighting control, industrial control systems, and the timer control of pumps, and other motorized appliance controllers.

The 7022ACT relay works by providing an output when it receives a signal from an external switch, timer, or controller. It then controls an electrical load by either keeping the circuit on for a preset time or shutting it off after a specified period of time. This is done via the device’s adjustable output delay and adjustable reset functions. Additionally, the 7022ACT has a "fast action" feature which accelerates the start and stop of the output after receiving a signal. This feature helps the user set up the relay to their specific requirements.

The 7022ACT relay is made with an isolated power line, as well as the ability to accommodate a wide array of voltages (including DC and AC). It is designed to be resilient, withstanding up to a 5 Amp current. The design also includes reinforced plastic housing with an LED indicator for easy monitoring and a sleek form factor for easy installation.

Overall, the 7022ACT is a versatile and reliable time delay relay. It can be used in a wide variety of applications, from appliance controllers to industrial control systems. With its robust design and adjustable functions, the 7022ACT is an ideal choice for any system requiring a time delay relay.
