        Features:

        • Receives sixteen 100–120 V AC field inputs.
        • Uses photocouplers between the AC circuits and PLC logic.
        • Occupies sixteen I/O points in a MELSEC-Q station.
        • Displays the recognized state of every channel on front LEDs.
        The terminal block carries the field voltage and grouped commons into the module.

        Isolated input stages translate those voltages into backplane logic states for the CPU.

        LED and PLC-monitor comparisons distinguish terminal-side faults from addressing faults.

        Following an AC field signal into the PLC image

        • Field voltage: A 100–120 V AC device applies voltage between an input and its group common.
        • Input network: The module conditions the AC waveform before the isolation stage.
        • Photocoupler: Optical isolation transfers the on/off decision to internal logic.
        • Backplane state: The accepted channel state appears at the assigned PLC input bit.

        Completing current paths for grouped field inputs

        • Group reference: Each documented common closes the field circuit for its associated inputs.
        • Shared failure: A loose common can disable several channels even when their signal wires are energized.
        • Terminal check: Voltage is measured from the input terminal to the correct common.
        • Circuit separation: Commons from unrelated supplies are not joined unless the wiring diagram permits it.

        Relating the sixteen terminals to software addresses

        • Module position: The installed slot establishes the input address range.
        • Channel order: Terminal numbers map in sequence to the sixteen PLC input points.
        • Project reference: Program symbols must use the address range assigned to the physical slot.
        • One-point test: Applying one signal at a time confirms terminal-to-bit correspondence.

        Using LEDs and software together to locate a missing input

        • LED off: Inspect field voltage, terminal seating and the correct group common.
        • LED on: The electrical input stage has recognized the field signal.
        • Bit off: An on LED with an off program bit points to address or project mismatch.
        • Multiple points off: Check the common and shared field supply before tracing individual conductors.
        Description
        Mitsubishi Electric QX10 is a MELSEC-Q 16-point digital input module for receiving 100–120 V AC field signals. It conditions those field voltages through isolated input circuits and transfers the resulting on/off states into the PLC input image.

        Each channel of QX10 uses a photocoupler to separate the AC field circuit from the internal logic path. When the applied voltage satisfies the input threshold, the corresponding PLC bit is set without carrying the field voltage onto the backplane logic.

        The screw terminal block of QX10 groups the field inputs around their documented common connections. Correct common placement completes the current path for all channels in that group, while an open common can make several points appear inactive together.

        Front LEDs on QX10 show the electrical state recognized by each input circuit. Comparing those LEDs with the PLC monitor separates a field-wiring problem from an address or program-reference problem.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why are several Mitsubishi QX10 LEDs off although field devices are energized?
        Check the affected group common and shared AC supply before tracing individual QX10 inputs.
        Can QX10 accept 24 V DC sensor signals?
        No. Mitsubishi QX10 is specified for 100–120 V AC input circuits, not 24 V DC sensors.
        Why is a QX10 LED on while the PLC input bit remains off?
        Confirm the QX10 slot address, project mapping and monitored device range in the MELSEC-Q program.
        How many PLC points does Mitsubishi QX10 occupy?
        Mitsubishi QX10 occupies sixteen I/O points for its sixteen digital input channels.
        How should AC wiring be separated around QX10?
        Route QX10 field conductors according to the cabinet wiring rules and keep each input with its documented common.
        What should be recorded before exchanging Mitsubishi QX10?
        Record the QX10 slot, terminal numbers, group commons and assigned PLC input range before removing wiring.
