Frequently asked questions

What is the difference between isolated and non-isolated inputs on the Siemens 6ES5420-4UA14?

Non-isolated inputs on the 6ES5420-4UA14 mean that the input circuitry is not electrically separated from the PLC's backplane. This can simplify wiring but requires careful consideration of grounding and potential voltage differences in your system compared to isolated modules.
