Solid-state relays (SSR) utilize semiconductor devices for switching control, eliminating mechanical wear and contact oxidation issues inherent in electromechanical relays. However, in practical applications, latent factors such as heat accumulation, long-term aging, and environmental wear can still cause SSR performance degradation or sudden failures, compromising circuit system stability. This blog dissects the 6 most common causes of SSR failures and provides corresponding solutions based on proper installation and maintenance practices. It offers clear guidance for practitioners to mitigate risks and extend equipment lifespan.

In industrial automation, temperature controllers adjust heating or cooling equipment based on temperature changes through different output methods. They don’t just read temperatures—they actively respond to them. The output method determines how the controller interacts with heaters, coolers, and alarms. Choosing the wrong one can lead to energy waste, unstable temperatures, or even equipment damage. Therefore, precise temperature control is not just about accuracy—it also requires selecting the right controller output method for your specific application. Below, we will explore the seven primary output types of temperature controllers and their impacts on system performance, efficiency, and service life.

Origin point return control is the control process in the automation system that makes the motion axis return to the preset mechanical origin. It is a standard operation when industrial automation equipment is started or reset. Realizing this function through the cooperation of HMI and PLC is a typical application in industrial automation. Today, ATO Automation will walk you through the complete setup process, from component introduction to system testing.
Pulse Width Modulation, or PWM, is a modulation technique that varies the width of the pulse in a periodic waveform while keeping a constant frequency. It involves repeatedly turning a signal on and off, with the width of each pulse representing the signal's amplitude. By adjusting the pulse width, PWM allows for precise control of the average power delivered to a load.
In many cases, we may need to run three-phase motors on a single-phase power source, especially in residential or small industrial environments without a three-phase power source. Although three-phase motors are more efficient and powerful, simply making some changes to the wiring and adding the correct components can make them suitable for single-phase 220V power supply. In this guide, ATO online store will guide you through the necessary steps to convert a three-phase motor to a single-phase power source for operation.
When converting a three-phase induction motor into a generator, correctly sizing the capacitors is crucial to ensure efficient operation. Capacitors are used to offset the inductive characteristics of the motor, improving its power factor and overall efficiency. If you're wondering, “What size capacitor should I use?”, this guide will walk you through the process of determining the correct capacitor size for your generator conversion project. In this tutorial, ATO industrial automation will explain what ‘capacitor size’ implies and provide you with all necessary formulas and important considerations you would need to figure it out yourself.
