Global Remote Input Output Modules Market to Reach $3.6 Billion by 2026 Remote I/O modules are designed to monitor and control process signals such as mA, volts, temperature, and digital signals. Growth in the global market is set to be driven by a host of factors including increasing investments in next-generation smart grids, rise in investment in industrial automation, increase in adoption of smart agriculture, greater usage of open-source software for remote I/O modules' programming and increased use of Ethernet-based remote I/O modules in discreet and process automation. Companies are also working on designing modules with higher bandwidths than available at present. The main aim is to design I/O modules with bandwidths that can be upgraded as and when the need arises in the future with help of a simple firmware change. The popularity of remote I/O modules can be attributed to the benefits they provide by easing the work at sites that not only span long distances but also employ large machines.
