Industrial relays are mechanical or electronic components that are used to control and manage high-voltage, high-current operations in industrial automation systems. They are used to control motors, pumps, fans, and other industrial machinery. Relays are used to create safety and control systems and are vital components of industrial automation and control systems. They are commonly used to protect the system from an overload situation, as well as for process control, for switching multi-speed motors and for multiple power control by activating contactors. Industrial relays come in many different types, such as electromechanical, solid-state, and time-delay. These different types of relays offer varying advantages and disadvantages, depending on their application.
