Solid State Relays (SSRs) are an important part of the industrial control and automation environment. The function of an SSR is to electrically switch the power on and off of various components. The D5D07K SSR is no exception, and its application field and working principle enable it to effectively control certain elements.

The industry application of the D5D07K SSR ranges from commercial equipment such as photocopiers, air conditioners, and vending machines, to industrial applications such as paper mills and textile factories. Its features and characteristics make it suitable for these applications, as it is highly reliable, has great insulation between the input and output, and great surge withstand capability.

In addition to applicability, the D5D07K SSR also has an excellent working principle. The circuit is composed of two main parts, the control side and the power side. On the control side, there is a small signal transistor that receives digital command signals. When the transistor is turned on, the power side of the relay is triggered and current flows between the input and output, when turned off the power side is off and the output is cut off. An accompanying protection circuit protects the control and power sides and prevent damage due to over-load or over-voltage. The SSR can also be equipped with an optical-isolation circuit, which further isolates the power and control sides and enhances its safety.

To ensure a stable and reliable switching, the SSR has a built-in hysteresis circuit that absorbs switching noise. This hysteresis circuit increases the flexibility of the SSR in different operating scenarios, and its saturation characteristics improves the control precision. In addition, the SSR also has an over-heating protection system for automation safety purposes. The SSR is equipped with a temperature-controlled switch, which will open the output if the temperature exceeds a certain level, protecting the SSR from being damaged.

The D5D07K SSR is a versatile and powerful device, capable of application across a wide range of industrial and commercial control settings. Its features such as great insulation, surge withstand capability, protection circuits, hysteresis compensation, and built-in temperature protection ensure a stable performance in many operating environments.
