Order now: Mitsubishi QX40 DC Input Module – 16 Points
Atlantechdrives provides the QX40, a high-density 16-point digital input module designed for the MELSEC-Q series. This module is the primary interface for sensing 24V DC signals from field devices such as limit switches, proximity sensors, and push-button stations, offering high-speed response and reinforced isolation.
- Input Type: 24V DC (Positive Common / Sinking)
- Number of Points: 16 Points
- Response Time: 1ms, 5ms, 10ms, 20ms, or 70ms (Configurable)
- Isolation: Photocoupler isolation
- Connection: 18-point screw terminal block
- Rated Input Current: 4mA (at 24V DC)
Technical Superiority: Precision Signal Sensing for High-Speed Logic
Secure now the QX40 to ensure accurate data acquisition in your manufacturing process. This module is technically superior due to its software-configurable input filter times, which allow engineers to tune the module for high-speed pulse detection or to filter out mechanical contact bounce from older sensors. The QX40 uses high-quality photocoupler isolation between the field-side terminals and the internal system bus, ensuring that voltage spikes or ground loops from the factory floor do not damage the CPU. When you procure the QX40, you are acquiring a module that features 16 individual status LEDs for rapid visual diagnostics. The sinking input design (Positive Common) is the standard for European and Asian machine architectures, providing a safe and reliable logic path for industrial control.
Installation Advice: Wiring and Common Terminal Setup
When installing the QX40, ensure the terminal block is securely clicked into place. Use 0.3 to 0.75 mm² (22-18 AWG) copper wire for all connections. Since the QX40 is a sinking module, the 24V DC (+) must be connected to the «COM» terminal, and the inputs are triggered when the terminal is connected to the DC common (-). We recommend using ferrules to prevent stray strands from causing short circuits between adjacent terminals. Sourcing your QX40 from Atlantechdrives ensures you receive a unit with high-integrity opto-isolators, protecting the speed and accuracy of your PLC’s input image.
Maintenance and Signal Monitoring
Maintenance of the QX40 is simplified by its modular terminal block, which can be removed without disconnecting the field wiring, facilitating rapid module replacement if necessary. Periodically check the «Input LED» display to verify that signal states match the real-world conditions of the sensors. Sourcing an authentic QX40 from Atlantechdrives guarantees the hardware quality required for 24/7 mission-critical operations.
FAQs
Q: What is the maximum distance for the QX40 inputs?
A: The maximum distance depends on wire gauge and EMI, but typically up to 100 meters is supported with shielded cabling.
Q: Can I change the response time for a single point?
A: No, the filter time is set for the entire 16-point group via the PLC parameter settings.
