Product Description
The QX42 is a digital input unit for MELSEC‑Q (QnU) series PLC systems, providing a high‑density 64‑point 24 VDC sink input interface for local I/O expansion. Designed for industrial automation environments, it integrates cleanly into Q‑series racks to capture discrete signals from sensors, switches, and machine interlocks. The module’s connector wiring approach supports efficient installation and serviceability while maintaining reliable signal integrity. Use it to scale input capacity where fast, deterministic PLC processing is required across large machines or cells. The QX42 is commercialized by Mitsubishi Electric and aligns with common compliance requirements for industrial control hardware. It is ideal for applications needing compact footprint, standardized 24 VDC inputs, and straightforward integration with the MELSEC‑Q architecture. Package includes the module only; cabling and terminal accessories are application‑specific and procured separately.
