The global signal conditioning modules market size is expected to reach USD 1.62 Billion at a steady CAGR of 3.7% in 2028, according to latest analysis by Emergen Research. This steady market revenue growth can be attributed to rapid shift to industrial automation processes and major increase in infrastructure development across manufacturing and industrial sectors. Rising need for applications such as in galvanic isolation of standard signals and measurement of voltage and current with voltmeters and ammeters respectively, are other key factors contributing to growing demand for and adoption of signal conditioning modules globally.
