The Mitsubishi QI60 is a 16-point interrupt input module designed for the MELSEC-Q Series PLCs. This module is ideal for applications that require rapid response to input signals, as it allows immediate interruption of the main program for prioritized tasks. With compatibility for 12V and 24V DC signals, the QI60 provides flexibility in handling various control requirements.

Technical Specifications and Supported Programs

    Input Channels: 16 interrupt input points, suitable for fast response in time-sensitive applications.
    Voltage Range:
        12V DC: 4mA per point
        24V DC: 10mA per point
    Interrupt Functionality: Allows high-priority input signals to interrupt the PLC’s main program, enabling real-time response to critical events.
    Isolation: Optical isolation on each input channel, providing enhanced protection against electrical noise and ensuring stable signal acquisition.
    Wiring: Screw terminals for secure and stable connections, designed for industrial settings.
    Environmental Conditions:
        Operating Temperature: 0-55°C
        Humidity: 10-90% RH (non-condensing)
        Vibration and Shock Resistance: Compliant with IEC 61131-2 standards for reliability in demanding environments.

Supported Programming Software: The QI60 module is compatible with GX Works2 and GX Developer, allowing users to set up interrupt conditions, monitor performance, and troubleshoot if needed.

Commissioning Notes and Recommendations

    Installation and Wiring: Install the module securely in the PLC rack, and verify wiring for both 12V and 24V DC configurations, with each input meeting its specified current requirement.
    Interrupt Testing: Use GX Works2 or GX Developer to configure and test interrupt functionality, ensuring each point responds correctly to input signals under simulated conditions.
    Routine Maintenance: Periodically inspect terminal connections to maintain stable input performance and prevent connectivity issues.

By following these guidelines, the QI60 module will provide reliable interrupt handling for applications that demand immediate response, making it suitable for control systems requiring high-priority input processing.
