I/O Modules — The Interface Between Logic and Reality
I/O (Input/Output) modules are how your PLC "senses" and "acts".
Input modules receive signals from sensors, switches, encoders.
Output modules control actuators, relays, motors, or alarms.
They come in digital and analog types, and must be matched carefully to your field devices and response needs.
A well-designed I/O layout is the difference between stable control and constant troubleshooting.
Coming next: CPU Modules — the core of decision-making.
