Mitsubishi QY80 – Digital Output Module for Q Series PLC

Detailed Overview of Mitsubishi QY80 – Digital Output Module for Q Series PLC

The Mitsubishi QY80 is a 16-point digital output module designed for use with Mitsubishi Electric’s Q Series Programmable Logic Controller (PLC) platform. As a part of the modular and scalable Q Series, the QY80 provides reliable and efficient digital signal output in industrial automation systems. It is ideally suited for a variety of discrete control applications, including manufacturing, packaging, material handling, and machine automation, where robust and high-speed switching is required.

QY80

Key Features and Specifications


  • Output Type: The QY80 is equipped with 16 transistor-type (sourcing) output channels, which provide 24V DC outputs for controlling field devices such as solenoids, relays, indicator lamps, and contactors. These outputs are of the sourcing type (PNP), supplying current to the connected load.


  • Output Current Capacity:

    • Maximum per point: 0.5 A

    • Maximum per common: 2.0 A

    • Maximum total module output current: 4.0 A


  • Isolation: The output points are divided into 4 groups (4 points per group), and each group is electrically isolated. This separation allows independent wiring and reduces the risk of cross-interference between loads with different potentials or characteristics.


  • Response Time: The module offers a fast switching time of approximately 0.1 ms ON/OFF, making it suitable for high-speed control applications that require immediate output response.


  • External Power Supply:

    • Rated voltage: 24V DC

    • Operating range: 19.2 to 30V DC

    • Power consumption: ~4.5W (including internal logic and load drive)


  • Connector and Wiring: The QY80 uses a removable terminal block for easy field wiring and maintenance. This terminal arrangement simplifies module replacement and minimizes system downtime.


  • Indicators: Each output channel has an individual LED indicator that shows the ON/OFF status of the point. These visual indicators aid in troubleshooting and allow for real-time diagnostics during commissioning and maintenance.


Installation and Compatibility

The QY80 is designed to fit into any base unit slot in a Mitsubishi Q Series PLC rack. It communicates with the Q CPU via the Q Series backplane, using Mitsubishi's proprietary high-speed data bus. It is compatible with all standard Q Series CPUs and can be configured using GX Developer or GX Works software platforms.


Environmental Ratings

  • Operating Temperature: 0°C to 55°C

  • Storage Temperature: -25°C to 75°C

  • Vibration Resistance: 5 to 9 Hz (1.75 mm amplitude), 10 to 150 Hz (acceleration of 4.9 m/s²)

  • Shock Resistance: 147 m/s² (15 ms pulse, 3 times each in X, Y, and Z directions)

  • Protection: Conforms to IP10 standard (when installed inside a panel)


Applications

The Mitsubishi QY80 is commonly used in industrial automation scenarios such as:

  • Controlling relay coils, solenoid valves, and contactors

  • Triggering indicator lights and audible alarms

  • Driving motor starters or actuators

  • Performing discrete ON/OFF control for machines and production lines


Its compact size, fast switching, and reliable operation make it ideal for densely wired control panels and systems requiring a high number of digital outputs in a small footprint.



Conclusion

The Mitsubishi QY80 digital output module offers a solid combination of performance, flexibility, and reliability for 24V DC discrete control applications. With 16 high-speed transistor outputs, robust electrical isolation, easy wiring, and compatibility with the powerful Q Series PLC platform, the QY80 is a dependable solution for industrial automation engineers seeking efficient and scalable digital control.
