Introduction to Time Delay Relays

Time delay relays are electric relays with a timing function. They are devices that are used to provide a delay before a particular event or process takes place. Typical features of time delay relays include adjustable time ranges and repeatability. Time delay relays are available in many different shapes and sizes and with a variety of features and functions.

SHS2.5S24A Time Delay Relay

The SHS2.5S24A time delay relay provides a delay in switching a circuit from one state to the next. The relay offers adjustable time ranges from 0.5s to 60s, repeatability accuracy ±0.2s, and adjustable tripping time. It is suitable for AC voltage control circuits and mainly used in controlling time for electric fan, lighting, street lamp and other current overload protection devices.

Application Field and Working Principle

The SHS2.5S24A time delay relay is commonly used in electrical control and switchgear applications for delay on, delay off, time regulation, phase sequence, and other events. It is a key component in controlling motors, pumps, and machinery in factories, as well as providing a delay to prevent equipment from tripping due to current overload.

The working principle of the SHS2.5S24A time delay relay is based on time-dependent control. A timing device, such as an electromagnet, is used to open or close contacts when the predetermined time has elapsed. A time switch is used to program the desired preset time, which is then converted into energy storage or energy release within the relay. When a control signal is initiated, the timing control device is activated, and a timer begins counting down. When the trigger/timer times out, the contacts in the relay are opened or closed.

Conclusion

The SHS2.5S24A time delay relay provides a reliable and cost-effective way to delay and control the switching of circuits. It is energy efficient and easy to install and operate. It is widely used in both industrial and domestic applications for its accurate preset time ranges and repeatability. As an effective and reliable time controlling device, the SHS2.5S24A time delay relay provides a high level of control with a minimal amount of effort.
