QX80 16-Point Digital Input Module 24V DC Source | Mitsubishi

The Original New Mitsubishi QX80 is a 16-point digital input module from the MELSEC-Q series, designed for reliable ON/OFF signal acquisition in industrial automation systems. It accepts 24 V DC source-type input signals and features an 18-point screw terminal block for field wiring. The module uses opto-isolator insulation between input terminals and the PLC power supply, ensuring reliable signal transmission in electrical noisy environments. As part of the MELSEC-Q QnU series, it integrates directly into Q series base units and is compatible with QnU, QnH, and other Q series CPU modules. Its compact 27.4 mm width and 98 × 90 mm footprint make it suitable for space-efficient control panel installations.
