Manufacturing industries involve processes that convert raw materials into finished products through various mechanical, chemical, or biological methods. Relays and industrial controls are essential in these industries for automating and regulating equipment, ensuring safety, and maintaining precise control over processes. For example, in May 2024, the Australian Bureau of Statistics, a national statistical agency based in Australia, reported that manufacturing industries in Australia saw an increase in EBITDA, rising to 51,574 in 2022, up from 50,446 in 2021. Therefore, the growth of manufacturing industries will fuel the growth of the relay and industrial controls market.

In the automotive sector, plug-in relays are gaining popularity due to their lightweight design compared to traditional electromechanical relays. These relays have the capacity to handle high-rated current and operating voltage levels, making them suitable for various automotive applications, including electrically heated catalytic converters, heater controls, and more. For example, Omron offers plug-in automotive relays ranging from 20A to 70A, which are used in applications such as motor control, wiper systems, and various body electronics functions in automobiles.

Leading companies in the relay and industrial controls market are focusing on the development of advanced supervisory control and data acquisition (SCADA) systems to gain a competitive advantage. These advanced SCADA systems provide real-time monitoring, remote operation, and data analysis to optimize system performance and ensure reliability. For instance, in October 2022, Emerson Electric Co. introduced Movicon.NExT 4.2, the latest version of its SCADA-based software. This software is built on an open framework that allows seamless integration with existing systems, reducing deployment costs, and enhancing performance and scalability.

In January 2022, TE Connectivity, a Swiss-based technology company, acquired Phoenix Contact Group (GEIS) to enhance its relay portfolio for various markets, including factory automation, elevators, and rail. This acquisition added single-pole, force-guided relay offerings to TE's product portfolio.

A relay is an electromagnetic switch that can be used to open or close an electrical circuit, thereby controlling the flow of electricity in one or multiple circuits through the activation of a single signal. Industrial control, on the other hand, refers to electronic control systems designed to monitor, regulate, and automate various processes within industrial settings.

The primary categories within relay and industrial control systems include distributed control systems (DCS), supervisory control and data acquisition systems (SCADA), and manufacturing execution systems (MES). A distributed control system (DCS) serves as a comprehensive platform for automating plant and industrial process control and operation, incorporating elements such as human-machine interfaces (HMI), logic solvers, historians, a common database, alarm management, and a common engineering suite. Various components are used in these systems, including modular terminal blocks, relays, optocouplers, surge protectors, marking systems, printing equipment, ferrules, cable lugs, hand tools, testers, enclosure products, PCB connectors and terminals, heavy-duty connectors, analog signal conditioners, electronics housing, power supplies, industrial Ethernet components, and remote I/O devices. Relay and industrial control systems find applications in automotive, industrial, telecommunications, household appliances, and various other fields.
