IO-Link - Electronic 28 V DC circuit breakers are specialized components primarily used in industrial automation and control systems. These devices are part of the broader IO-Link technology, which is an international standard (IEC 61131-9) for point-to-point communication in industrial applications. The brand is associated with companies like IFM Electronic (Germany), Balluff (Germany), and Pepperl+Fuchs (Germany), which are leading manufacturers in industrial automation. These electronic circuit breakers are designed for 28 V DC applications, providing reliable protection against overcurrent and short circuits in machinery, robotics, and process control systems. They are widely used in manufacturing, automotive, and energy sectors, offering smart diagnostics and easy integration with IO-Link-enabled systems.
