Introduction

Time Delay Relays are categorized under electromechanical relays. They perform a function normally done by a timer or programmer. Like other relays, these hold a stake on a contact to affect a change in a system.

CHB-38-70023 Application Field and Working Principle

CHB-38-70023 time delay relays are often used for an array of industrial, commercial, and residential applications. They can offer a wide variety of features such as periodic retriggering with set time delay. They are also suited for high-level circuit protection for motor starters, quick off cycles in machine controls, and short-off delays in big-production lines.This time delay relay works by energizing an electronic component in the relay. This allows it to be energized for a set time determined by the user. The timing mechanism can be adjusted using a variety of methods, including a potentiometer or switch inputs. The circuit works in such a way that the relay energizes when the input voltage is applied and the timer starts to countdown the time delay when the energy is turned off. Once the time delay has elapsed, the relay will deenergize and remain in this de-energized state until the input voltage is again applied.

Technical Specifications and Design

The CHB-38-70023 time delay relay offers a wide array of features which makes it an ideal choice for applications such as motor starters, machine control, and production lines. It has adjustable time ranges of 0.1 second to 10 hours and can be triggered using a start/stop input. It features a compact design, measuring 40 x 20 x 17.5mm in size. Additionally, it offers two contact sets, SPDT, for general purpose use as well as socketed and surface mount options for flexible installation. Additionally, the device also offers multiple protection features such as surge suppression, reverse phase sequences and high-level protection from shorting. It has a dedicated output terminal to simplify wiring and a bright LED indicator to help identify the status of the device. It also complies up to industrial standard regulations, including UL/CUL, CE and ABYC.

Conclusion

The CHB-38-70023 time delay relay offers a wide variety of features to suit various applications. It is designed for easy installation and offers efficient performance. With advanced protection features and adjustable time delay settings, the CHB-38-70023 provides a reliable and cost-effective solution for all types of commercial and industrial applications.
