SHSP100M110A

Time Delay Relays are a type of electrical relays that allow a programmed time delay between the moment of an input signal is sent and the moment of an output signal is supplied. These relays offer great flexibility and precision in controlling the opening and closing of electrical currents in a system. One specific type of time delay relay is the SHSP100M110A. The application field and working principle of the SHSP100M110A is described in this article.

Application Field

The SHSP100M110A time delay relay is used in various applications, such as starting and stopping motors, cutting power, controlling door latch mechanisms, and controlling lighting systems. The relay can also be used as an alarm delay, to delay the start of an alarm system or to extend the time for which the alarm is active. Another popular use of the SHSP100M110A is to control the speed of fans, pumps and other rotating machinery.

Working Principle

The SHSP100M110A time delay relay has a delay mechanism that is based on the core principle of a simple RC circuit. When a current is passed through the relay, it causes the capacitor to become charged. This sets off a timer while also powering the device. As the timer runs, the capacitor begins to discharge, causing the device to switch off. This process can be programmed to take a specific amount of time according to the user’s requirements.

In addition to the RC delay circuit, the SHSP100M110A also features a low voltage power supply circuit, a high-voltage contact-delay circuit and a Logic Control Circuit. The Logic Control Circuit is responsible for the basic function of the relay. The contact-delay circuit connects the control voltage that activates the relay and the output voltage that is given after the timer has finished counting down. The low voltage power supply circuit is responsible for providing the necessary voltage for the Logic Control Circuit, contact-delay circuit and RC delay circuit.

The SHSP100M110A time delay relay is a very reliable and versatile device that can be used in a variety of applications. Its precise timing mechanism and low voltage power supply circuit makes it an ideal choice for controlling any electrical system. The device also has an adjustable voltage range and can be programmed to meet specific time-based requirements.
