Industry 4.0 is driving an explosion of diagnostic data on the factory floor, enabling systems to become smarter and equipment to become more reliable through predictive maintenance. One area lacking in data, however, is the 24-V dc power-distribution system, which carries power to programmable-logic controllers (PLCs), robots, machine tools, and other industrial equipment.
Troubleshooting the 24-V dc power system often requires a tedious process of manually checking LED indicators and disassembling power modules, all of which extends downtime and reduces productivity.
