Protecting the 24-Volt Direct Current (DC) System – The Backbone of Industry 4.0
Industrial automation is rapidly evolving from rigid, standalone systems into interconnected, intelligent networks that define Industry 4.0. Modern industries are not just automated - they’re hyperconnected with thousands of sensors, controllers and many sophisticated devices. The fusion of digital technologies — particularly the Industrial Internet of Things (IIoT), with its sensor-generated real-time data streams — powers this transformation by facilitating predictive maintenance and dramatically cutting unexpected equipment failures. In the world of modern manufacturing, where precision sensors, complex logic controllers and interconnected devices drive production, there is one constant across multiple architectures – the power source which is a 24-volt direct current (DC) system.
