[INSTALLATION PRECAUTIONS]

!CAUTION

•Use the PLC in an environment that meets the general specifications contained in the user's manual of the CPU module to use.

Using this PLC in an environment outside the range of the general specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the product.

•When installing the module, securely insert the module fixing tabs into the mounting holes of the base unit while pressing the installation lever located at the bottom of the module downward. Improper installation may result in malfunction, breakdown or the module coming loose and dropping.

Securely fix the module with screws if it is subject to vibration during use.

•Tighten the screws within the range of specified torque.

If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.

If the screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

•Switch all phases of the external power supply off when mounting or removing the module. Not doing so may cause damage to the module.

The system that uses the QnPHCPU allows you to change a module online. Note that there are restrictions on the modules that can be changed online and each module has a predetermined changing procedure. For details, refer to the chapter of online module change in this manual.

•Do not directly touch the conductive area or electronic components of the module.

Doing so may cause malfunction or failure in the module.

[WIRING PRECAUTIONS]

CAUTION

•Always ground the FG terminal for the PLC. There is a risk of electric shock or malfunction.

•When turning on the power and operating the module after wiring is completed, always attach the terminal cover that comes with the product.

There is a risk of electric shock if the terminal cover is not attached.

•Tighten the terminal screws within the range of specified torque.

If the terminal screws are loose, it may result in short circuits or malfunction.

If the terminal screws are tightened too much, it may cause damage to the screw and/or the module, resulting in short circuits or malfunction.

•Be careful not to let foreign matter such as sawdust or wire chips get inside the module. They may cause fires, failure or malfunction.

•The top surface of the module is covered with protective film to prevent foreign objects such as cable offcuts from entering the module when wiring.

Do not remove this film until the wiring is complete.

Before operating the system, be sure to remove the film to provide adequate ventilation.

Q68ADV, Q68ADI, Q64AD specifications

Mitsubishi Electronics, a renowned leader in automation technology, has developed advanced analog input modules that play a crucial role in numerous industrial applications. Among them, the Q64AD, Q68ADI, and Q68ADV models stand out with their impressive features and capabilities tailored for precise data acquisition and control.

The Q64AD module is designed for high-performance analog signal processing. It offers up to 16 channels of differential input, making it suitable for applications requiring multiple sensor readings simultaneously. The resolution of 16 bits enables accurate data capture, ensuring that subtle variations in process variables, such as temperature or pressure, are detectable. One of its key advantages is the high-speed sampling capability, allowing data collection at rates of up to 100 milliseconds per channel, essential for real-time monitoring in fast-paced environments.

In contrast, the Q68ADI model enhances the versatility of the analog input system. It includes built-in isolators, providing additional protection against noise and interference commonly found in industrial settings. This isolation feature improves the reliability of sensor readings, especially in harsh environments where electrical noise can impact performance. Furthermore, the Q68ADI supports both voltage and current input types, making it adaptable to various sensor configurations, such as thermocouples and RTDs, expanding its usability across different applications.

The Q68ADV module takes versatility a step further by integrating advanced diagnostic features. This model offers a range of additional functions, including built-in fault detection and self-diagnosis capabilities that identify issues before they escalate into significant problems. It also features temperature compensation and linearization algorithms, which enhance the accuracy of reading from thermocouples and other temperature sensors. The Q68ADV module is ideal for applications demanding high reliability and stringent performance standards, making it indispensable in industries like pharmaceuticals and food processing.

All three models are designed to seamlessly integrate with Mitsubishi's PLC systems, ensuring smooth communication and data exchange. They support various protocols, making them compatible with a wide range of devices and systems. Collectively, the Q64AD, Q68ADI, and Q68ADV modules exemplify Mitsubishi Electronics' commitment to delivering high-quality, reliable, and innovative solutions in industrial automation, empowering businesses to achieve greater efficiency and operational excellence.
