IO-Link electronic 24 V DC circuit breakers are advanced electrical protection devices designed for industrial automation, primarily distributed by leading manufacturers such as IFM Electronic (Germany), Phoenix Contact (Germany), and Weidmüller (Germany). These circuit breakers are widely used in manufacturing, robotics, and process control industries to safeguard low-voltage DC circuits (24V) from overloads and short circuits. Key products include configurable modular breakers, smart monitoring variants with IO-Link communication, and compact DIN rail-mounted units. The IO-Link integration enables real-time diagnostics and remote configuration, aligning with Industry 4.0 standards. Major applications include PLC systems, sensor networks, and motor control panels.
