Mitsubishi QX10 PLC Digital Input Module, 16 Points, 100-120 VAC Q Series

Description:

The Mitsubishi QX10 is a digital input module from the MELSEC-Q series designed to interface 100–120 VAC field signals with PLC systems. Commonly installed in PLC racks within control panels, it enables reliable acquisition of discrete AC input signals from switches, relays, and sensors. Maintenance teams, system integrators, and OEMs use this module for distributed input monitoring, system expansion, and replacement of legacy input modules in industrial automation environments.

Applications:

This digital input module is used in industrial automation systems requiring AC signal monitoring. Typical applications include conveyor systems, manufacturing lines, packaging equipment, and process control systems where 100–120 VAC input devices such as pushbuttons, limit switches, and relays must be reliably interfaced with a PLC for control and monitoring.
