The Mitsubishi Electric QX80 is a 16-point DC input module for the MELSEC-Q series PLCs, providing a dedicated digital input interface for automation projects. It offers 16 discrete input channels to connect external DC devices, feeding signals directly into the MELSEC-Q controller for processing. By adding the QX80, the MELSEC-Q system gains additional input capacity for sensors, switches, and other digital devices in a single rack. Typical applications include factory automation, process monitoring, and machine control where multiple digital inputs are required by a MELSEC-Q setup.
