Click to follow and unlock more PLC technology knowledge! Introduction Many newcomers to the industrial control field often wonder: since PLCs come with built-in relay outputs, why do we need to add an extra row of external relays to control contactors? Doesn’t this increase costs and complicate the system? In fact, there is profound electrical … Read more
“A good-looking board must be functional!” This is a statement made to me by a hardware engineer. In circuit design, not only is extensive professional knowledge required, but it is also essential to consider the manufacturability of the circuit board during the design process, as the final design needs to be produced and used. I … Read more

In the field of automation control, both PLC (Programmable Logic Controller) and microcontrollers are extremely important control devices, each possessing unique advantages and disadvantages suitable for different application scenarios. Advantages of PLC 1. Simple programming and easy to learn: PLC uses a ladder diagram programming method similar to relay control circuit diagrams, which is intuitive … Read more
PLCs and Industrial PCs (IPCs) are two different control devices in the field of industrial automation, both play important roles in industrial automation, but there are significant differences in functionality, application, and structure between IPCs and PLCs. Hardware and Reliability Industrial PCs adopt a rugged hardware design, featuring a complete computer architecture, including processors, memory, … Read more
The factory defect rate of an MCU (Microcontroller Unit), usually expressed in PPM (Parts Per Million), is a highly variable value that depends on several key factors. For mainstream, mature MCU manufacturers and product lines, the factory defect rate can typically be controlled at a very low level, generally ranging from 10 PPM to 100 … Read more

A washing machine product selected two different manufacturers’ MCUs with pin compatibility. During EMC certification, it was found that MCU A failed at 5kV, while MCU B could withstand up to 8kV, with all other components and environments being identical. Why do different MCU products exhibit varying ESD levels? The reasons behind this are not … Read more
Our company received a product returned from the market for repair. Testing revealed that the product would freeze after running for a period of time (possibly a few minutes or hours, the duration is uncertain). Upon checking the hardware circuit, no anomalies were found. After replacing the MCU, it was discovered that the issue followed … Read more
