Product Overview
The Mitsubishi QX40H is a high-performance high-speed digital input module from the industry-leading MELSEC Q series PLC platform. It is specifically designed for applications requiring ultra-fast signal acquisition and processing, delivering industry-leading response times down to 0ms (typical) when the noise filter is disabled. This module features 16 sink-type (positive common) DC24V inputs with adjustable filtering options, providing the perfect balance between speed and noise immunity for demanding industrial environments. It is fully compatible with all Q series CPU modules and base units, making it an essential component for high-speed automation systems.
Key Advantages & Core Features
- Ultra-Fast Response: Industry-leading 0ms typical response time (no filter mode) for real-time signal capture
- Adjustable Noise Filter: 5-level software-selectable filtering (0.1/0.2/0.4/0.6/1ms) for optimal noise immunity
- High Input Current: 6mA per point (vs 4mA for standard QX40) for improved signal reliability in long-distance wiring
- 100% Simultaneous ON Capability: All 16 inputs can be active at the same time without performance degradation
- Photocoupler Isolation: 560V AC rms isolation between input circuits and PLC system for enhanced safety
- Individual Status LEDs: LED indicator for each input point for quick diagnostics and troubleshooting
- Compact Design: Standard Q series module form factor, occupying only 1 slot on the base unit
- Global Compliance: CE, UL/cUL, RoHS, KC certified for worldwide industrial use
