Metso Valmet A413015 Drive Board

I. Overview

The Metso A413015 is an industrial-grade high-precision analog input/output module, mainly designed to be compatible with the control systems of Metso crushing and screening equipment (such as cone crushers, vibrating screens, heavy-duty feeders, etc.). It undertakes the core functions of "on-site analog sensor signal acquisition (e.g., pressure, temperature, liquid level) - signal amplification and filtering - standard signal output to actuators". Its design focuses on "signal acquisition accuracy" and "anti-interference capability" for heavy-duty industrial scenarios. It adopts high-precision ADC/DAC chips and a multi-layer electromagnetic shielding structure, which can effectively suppress mechanical vibrations, electromagnetic radiation, and dust interference in crushing workshops, ensuring stable transmission and accurate conversion of analog signals. It is widely used in industries with strict requirements for parameter monitoring accuracy, such as mining, building materials, and metallurgy.

Compared with general-purpose analog modules, this module features "in-depth compatibility with Metso equipment protocols", "wide-range signal adaptation", and "fault self-diagnosis". It can be directly integrated into Metso C100/C200 series control cabinets, enabling seamless connection with the crusher's main controller, high-precision sensors (e.g., pressure transmitters, temperature sensors), and actuators (e.g., proportional valves, frequency converters). This ensures the accurate regulation of key process parameters such as load adjustment and pressure control of crushing equipment.

III. Functional Features

1. High-Precision Signal Processing and Multi-Type Adaptation

• Wide-Range Signal Compatibility: The 4 input channels support dual-type signals (4-20mA/0-10V DC), and the 2 output channels also support dual-type signals. Each channel can be independently configured via DIP switches. It can be compatible with different devices such as pressure transmitters (4-20mA), temperature sensors (0-10V DC), and proportional valves (4-20mA) without replacing the module, reducing on-site selection and spare parts costs;

• High Sampling Accuracy and Stability: Adopting 16-bit high-precision ADC/DAC chips, the input/output accuracy reaches ±0.1% FS, and the temperature drift is ≤0.05% FS/°C. This ensures accurate monitoring and control of key parameters of crushing equipment (e.g., crusher spindle pressure, hydraulic system oil temperature), avoiding equipment overload or process deviations caused by signal errors.

2. Anti-Interference Design for Heavy-Duty Industry

• Triple Electrical Isolation: The power supply, input, and output circuits are isolated from each other (isolation voltage 2000V AC), which can effectively block the interference of surge voltage and electromagnetic radiation generated by the start-stop of the crusher motor on analog signals. This avoids input signal distortion (e.g., pressure signal fluctuation) or output signal drift (e.g., unstable control voltage of proportional valves);

• Built-In Filtering and Shielding: The input channels integrate a 10Hz low-pass filter to filter out high-frequency electromagnetic noise (e.g., interference generated by frequency converter operation); the module housing adopts a metal shielding layer to further reduce the impact of external electromagnetic radiation, making it suitable for high-interference environments such as mining and metallurgy.

3. Convenient Operation & Maintenance and Fault Diagnosis

• Full-Channel Status Indication: 10 LED indicators are installed on the front - power indicator (green, constant on indicates normal power supply), input signal indicators (4 channels, lit indicates normal signal access in the corresponding channel), output signal indicators (2 channels, lit indicates output activation in the corresponding channel), communication indicator (red, flashing indicates normal communication), and alarm indicator (yellow, constant on indicates module fault). The signal flow and module working status can be quickly judged without an oscilloscope;

• Fault Self-Diagnosis and Alarm: Equipped with a built-in fault detection circuit. When "power overvoltage/undervoltage", "input signal overrange", "output short circuit", or "communication interruption" occurs, it will send fault codes to the main controller via RS485 (e.g., E01 indicates power fault, E06 indicates input signal overrange, E11 indicates output short circuit). At the same time, it triggers the yellow alarm light to stay on. When used with the Metso TP150 operation panel, the fault type and location can be directly displayed, shortening the fault location time.

4. Exclusive Collaboration with Metso Equipment

• In-Depth Protocol Compatibility: Supports Metso's exclusive control protocol for crushing equipment, and can directly communicate with the Metso C100 main controller and TP150 human-machine interface (HMI). No additional communication driver programming is required, enabling real-time closed-loop control of "sensor data - main controller - operation panel - actuator" (e.g., automatically adjusting the feeder speed according to the pressure at the crusher feed inlet);

• Process Adaptation Optimization: Built-in signal calibration logic for common parameters of Metso crushing equipment (e.g., linear calibration of cone crusher spindle pressure signals, compensation of vibrating screen amplitude signals). No on-site manual calibration is required, simplifying the module debugging process;

• In-Cabinet Integration Optimization: Its size is adapted to the layout of Metso standard control cabinets. The DIN rail mounting method is compatible with Metso power modules (such as Metso A413200) and digital modules (such as Metso A413345), enabling modular stacked installation. This reduces space occupation inside the cabinet and lowers the complexity of system integration.
