Product Description
Q68AD-G Mitsubishi Universal Model Redundant Power Supply Module 100 To 240 V AC
Product Description
The Mitsubishi Q68AD-G is a high-performance analog-to-digital (A/D) conversion module designed for the MELSEC Q Series of Programmable Logic Controllers (PLCs). This module is engineered to receive analog voltage or current signals from field instruments (such as sensors and transmitters) and convert them into high-resolution digital values for processing within the CPU. It is a critical component for industrial automation applications requiring precise monitoring and control of process variables like temperature, pressure, flow, and level. The Q68AD-G offers high accuracy, fast conversion speeds, and robust reliability, making it suitable for complex and demanding industrial environments.
Key Features
- High Channel Density: Provides 8 analog input channels in a single module slot, saving space in the PLC base unit.
- High Resolution: Offers exceptional resolution of 1/60,000, ensuring highly accurate digital representation of analog signals for precise control.
- Flexible Input Ranges: Supports a wide selection of analog input ranges, including:
- Voltage: -10 to +10 V DC, 0 to 5 V DC, 1 to 5 V DC, etc.
- Current: 0 to 20 mA DC, 4 to 20 mA DC (with built-in fault detection for 4-20mA signals).
- Fast Conversion Speed: Achieves a high-speed conversion of 80 µs per channel, allowing for rapid system response to process changes.
- Built-in Functions: Includes advanced functions such as scaling, input signal error detection (wire break, overrange/underrange), and sampling processing, simplifying program logic.
- Easy Setup: Can be easily configured using GX Works2, Mitsubishi's integrated engineering software, for setting parameters without complex programming.
Material & Applications
- Material: The module is constructed with a robust plastic housing and a metal connector for durability. The internal circuitry uses high-quality electronic components to ensure stable operation in industrial conditions.
- Primary Applications: Widely used in various industries for process automation, including:
- Factory Automation: Monitoring motor speeds, pressure in hydraulic/pneumatic systems.
- Environmental Control: Measuring temperature and humidity in HVAC systems.
- Water and Wastewater Treatment: Monitoring pH levels, flow rates, and tank levels.
- Food and Beverage: Controlling process variables like temperature and fill levels.
