There has always been a huge number of sensors available for all sorts of industrial applications and with the advent of the Industrial Internet of Things (IoT) these devices are now connected to global networks and individually addressable.
Industrial IoT sensors are widely used in different industries to monitor equipment, assets, systems, and overall performance. Real-time data is then analysed and transmitted to a company’s centralized system. Management can then make informed decisions about maintenance priorities and future asset replacement needs.
Although many sensors are now battery powered, in this article we discuss solutions for traditional wired applications using a 12V or 24V supply. Small size and high efficiency are still important as space is often limited and good thermal management is necessary.
Below we illustrate a typical power architecture and demonstrate how our products can be used.
