Top 20 PLC Manufacturers : PLC Brands and Ranking

Top 20 PLC Brands | PLC Manufacturers

Before starting this blog, I recommend you to read about What is PLC? How does it work? What are their applications? Advantages of PLC.

PLC or programmable logic controller is also called the “Workhorse of the Industrial Automation”, is an industrial computer that is specially designed to control the specific process or sometimes the entire production line.

There are multiple shapes and sizes of PLC. As it is an industrial computer, it doesn’t look like a conventional computer. It doesn’t have a display screen, keyboard, and mouse.

You can find PLC in almost all sectors. PLC replaces relays. Relays are the devices that are generally used to control high power signal using a low power signal. Relays logic is time-consuming and said to be complex when they tend to be re-configured. PLCs have less downtime as compared to relay logic.

Although, Panel size in relay logic is more space-consuming as compared to panel size with PLC. Programmable Logic Controller is ruggedized hardware. The word ruggedized means that the PLC’s hardware is capable of operating in harsh environments and longer-lasting.

A Growing Market of Industrial Automation

According to research by grandviewresearch, the global industrial automation, and control system market was worth almost 126.3 billion USD and expected to rise 8.6% up to 2025. Companies are significantly reducing labor and operational expenses, and additionally minimizing human errors by the use of industrial robots through automation.

The manufacturers are using various control systems for their industrial processes. The primary control systems are Programmable Logic Controller(PLC), Supervisory Control And Data Acquisition(SCADA), Distributed Control System(DCS), and Human Machine Interface(HMI).

Based on the region, the market for industrial automation has been categorized into North America, Europe, Asia Pacific, Latin America, and the Middle East and Africa.

A large portion of the growth is expected to come from the Asia Pacific. Kawasaki Robotics, Mitsubishi Electric Factory Automation, Yokogawa Electric Corporation are some of the key players from the Asia Pacific.
