6SE6440-2UD31-1CA0 MITSUBISHI Analog Input Module

Product  Description：

The Mitsubishi Electric Analog Input Module is a high-performance component designed for the MELSEC programmable logic controller (PLC) series, such as the iQ-R, iQ-F, and Q Series. These modules act as the bridge between the physical world and the digital controller by converting continuous analog signals—like temperature, pressure, or flow—into digital data that the PLC can process.

Product Specifications

Mitsubishi offers a variety of modules tailored to different precision needs, but they generally share the following technical characteristics:

• Input Channels: Available in configurations of 2, 4, or 8 channels per module to accommodate various system scales.

• Input Ranges: Supports standard voltage inputs (0-5V, 1-5V, 0-10V, -10 to +10V) and current inputs (0-20mA, 4-20mA).

• Resolution: High-resolution options often reach 16-bit signed binary, providing granular data for sensitive processes.

• Conversion Speed: Rapid sampling rates, with some high-speed modules achieving conversion times as low as 80 microseconds per channel.

• Isolation: Channels are typically isolated from the internal bus and, in high-end models, from each other to prevent electrical interference.

• Accuracy: Precision levels usually range within ±0.1% to ±0.3% of the full scale at ambient temperatures.

Product Advantages

Mitsubishi analog modules are recognized in the industry for their reliability and ease of integration.

• High Precision and Stability: The advanced filtering technology minimizes noise interference, ensuring that the digital value remains stable even in electrically noisy industrial environments.

• Seamless Integration: Designed specifically for the MELSEC ecosystem, these modules require no complex communication protocols; they are automatically recognized by GX Works3 software.

• Intelligent Features: Many modules include built-in scaling functions, allowing the PLC to read values in engineering units (like Celsius or PSI) directly without additional ladder logic.

• Compact Design: The slim profile saves valuable space in the control cabinet, allowing for high-density I/O configurations.

• Durability: Built to withstand harsh industrial conditions, including vibrations and varying temperature ranges.

Important Considerations and Precautions

To ensure longevity and accuracy, certain guidelines must be followed during installation and operation.

• Wiring Separation: Always route analog signal cables away from high-voltage power lines or motor cables to prevent electromagnetic induction.

• Shielding: Use twisted-pair shielded cables for all analog inputs and ensure the shield is properly grounded at a single point.

• Current/Voltage Matching: Verify that the physical switch settings or software configuration matches the actual input signal type (e.g., don't send a 10V signal to a channel configured for 4-20mA).

• External Power Supply: Many modules require an external 24V DC power source; ensure this power is stable and within the specified voltage tolerance.

• Unused Channels: It is best practice to short-circuit unused current input terminals or disable them in the software configuration to prevent ghost readings or errors.

Product Applications

These modules are essential in any industry requiring precise monitoring and feedback loops.

• Manufacturing and Assembly: Monitoring hydraulic pressure in presses or torque in automated fastening systems.

• HVAC and Climate Control: Reading temperature and humidity sensors to regulate large-scale industrial cooling systems.

• Water Treatment: Measuring pH levels, flow rates, and tank levels to automate chemical dosing.

• Food and Beverage: Controlling oven temperatures or monitoring weight scales for packaging consistency.

• Energy Management: Monitoring voltage and current fluctuations in power distribution panels.
