Modern PLC forums are not just about hardwired connections anymore. The scope of "PLC elettronica" has expanded to include: A PLC does not operate in a vacuum;
While PLCs are computational devices, their function is inherently tied to the physical world of electronics. A PLC does not operate in a vacuum; it relies on low-voltage DC electronics for inputs (reading signals from proximity sensors, limit switches, and transducers) and outputs (driving contactors, solenoid valves, and motor starters).
