Introduction to Time Delay relays and the CB-1011B-79

Time delay relays are digital electronic devices that delay the energizing or de-energizing of a contactor or other load device until the completion of an adjustable delay period when the conditions applied to the set of input terminals are satisfied. The working principle of time-delay relays is based on the fact that current must pass through several components, including a resistor and a capacitor, before it can reach the output. A time delay is created when the conditions of the input terminal are not met or the current is not allowed to flow immediately.Applications of time delay relays span a broad spectrum in industrial and commercial settings. These may include everything from automatic door openers to emergency stop switches to smoke detectors. Some of the more specific applications of time delay relays include power failure alarm circuits, automatic transfer switches, security monitor systems, and surge protection systems.The CB-1011B-79 time delay relay is an example of a compact and cost effective solution for implementing time delay functionality in industrial and commercial applications. This particular relay offers digital output and set up via a keypad for adjustable timing periods. It also features up to six programmable time delays with LED indication and a maximum load of 250 VAC at 6A. This model is designed for use with single-phase and three-phase power systems, and provides a reliable and durable solution with a long service life.

Description of the Working Principle of the CB-1011B-79

At the heart of the CB-1011B-79 time delay relay lies its working principle, which consists of an adjustable delay period. This delay period is created when input terminals of the relay are not met, or when the current is not allowed to flow immediately. The timing period begins when an input is received, and the relay contacts then remain open for the set amount of time. This delay period is adjustable by a simple keypad input, allowing the user to adjust the timing period according to the needs of the particular application.The CB-1011B-79 utilizes a low-voltage DC power supply, either through AC-DC power supplies or direct-current sources. When the input terminals are met and the DC power is applied, current passes through the delay contacts and the resistor and capacitor. The resistor acts as a current-limiting device, while the capacitor simulates an inductive load, which is necessary to control current. When the input to the relay is removed, the capacitor stores the current in its dielectric material, thus creating a delayed action.

Benefits of Using the CB-1011B-79

The CB-1011B-79 time delay relay provides a number of advantages over its predecessor designs, including a reduced component count, high accuracy, and improved performance. This improves the overall reliability and stability of the system, offering great cost savings to users.The CB-1011B-79 also features an adjustable timing period, and this is facilitated by a simple two-button keypad that is used to control the programmable time delay setting. This allows for a greater degree of flexibility in the application, as different time period settings can be easily selected to better suit the particular requirements of the application.In addition, the CB-1011B-79 is designed to operate in harsh industrial environments, which makes it a great choice for applications that require reliable and durable solutions. It has a maximum load of 250VAC at 6A, and it is designed to safely operate in temperatures ranging from -20° to +85°C. The CB-1011B-79 also meets the strict requirements of EMI emission and immunity.

Conclusion

The CB-1011B-79 time delay relay is a reliable and cost effective solution for implementing adjustable timing in industrial and commercial applications. This particular relay model offers digital output and setup with a simple two-button keypad for adjustable timing periods, and it offers a maximum load of 250 VAC at 6A.
