HF-SP202BG1H 1/6 MITSUBISHI

HF-SP202BG1H 1/6 MITSUBISHI analog module

Product  Description：

Mitsubishi Electric Analog Modules are high-precision components within the MELSEC PLC range that facilitate the interface between a digital control system and the continuous, variable signals of the physical world. These modules are categorized into Analog Input (A/D) modules, which convert signals from sensors into digital data, and Analog Output (D/A) modules, which convert digital instructions into voltage or current to control equipment like valves and variable speed drives.

Product Parameters

The technical performance of Mitsubishi Analog Modules is defined by their precision, speed, and signal compatibility:

• Signal Ranges: Supports standard voltage inputs and outputs such as 0 to 5V DC, 1 to 5V DC, and -10 to 10V DC, as well as current signals like 0 to 20mA and 4 to 20mA DC.

• Digital Resolution: High-fidelity conversion typically offering 12-bit, 14-bit, or 16-bit resolution, providing digital values up to 32,000 or 64,000 for maximum granularity.

• Channel Density: Available in configurations of 2, 4, 8, or 16 channels per module to accommodate different system scales.

• Conversion Speed: High-speed variants can achieve sampling rates as fast as 10 microseconds per channel, essential for high-speed motion and pressure control.

• Accuracy and Linearity: Precision engineering ensures an overall accuracy of ±0.1% to ±0.3% of the full scale at ambient temperatures.

• Isolation: Robust galvanic isolation (often using photocouplers) between the external terminals and the internal PLC logic to protect against surges.

Product Advantages

Mitsubishi Analog Modules are distinguished by their advanced processing capabilities and reliability:

• Integrated Intelligence: Many modules feature built-in functions for scaling, which converts raw electrical signals directly into engineering units like Bar, Celsius, or Liters per Minute.

• Sophisticated Filtering: Includes adjustable digital filters and first-order delay filters to eliminate high-frequency noise and signal jitter from the field.

• Comprehensive Diagnostics: Equipped with hardware detection for wire breakage, out-of-range detection, and error logging, allowing for rapid maintenance response.

• Simplified Configuration: Settings are managed through a graphical interface in GX Works software, eliminating the need for complex manual programming of buffer memory.

• High Noise Immunity: Designed with superior electromagnetic compatibility (EMC) to maintain signal integrity in environments with heavy electrical interference from motors and inverters.

Product Applications

These modules are the primary tools for process monitoring and precise machine control:

• Thermal Management: Controlling industrial heaters and cooling fans by monitoring temperature sensors like thermocouples or RTDs.

• Pressure and Flow Control: Managing chemical dosing pumps and hydraulic systems in water treatment or manufacturing plants.

• Tension and Torque Control: Maintaining constant tension in web-handling machines, printing presses, and wire-winding equipment using load cell feedback.

• Position Sensing: Interfacing with linear potentiometers or ultrasonic sensors to determine the exact position of a mechanical arm or platform.

• Speed Regulation: Sending analog speed references to variable frequency drives (VFDs) to coordinate multi-motor conveyor systems.

Important Precautions

To ensure long-term accuracy and protect the hardware, the following precautions should be observed:

• Shielding Practices: Use shielded twisted-pair cables for all analog signal lines. The shield should be connected to the ground terminal on the PLC side only to avoid creating ground loops.

• Physical Separation: Maintain a distance of at least 100mm between analog signal cables and high-voltage power lines or motor cables to prevent inductive noise.

• Unused Channel Management: For unused input channels, it is recommended to short-circuit the voltage terminals or disable the channels via software to prevent ghost signals caused by induction.

• External Power Stability: When using modules that require an external 24V DC power supply, ensure the supply is regulated and ripple-free to avoid measurement errors.

• Correct Signal Matching: Double-check that the hardware wiring matches the software configuration (e.g., do not send a voltage signal to a channel configured for current), as incorrect settings can cause inaccurate readings or hardware stress.
