Metso Valmet A413345 Thermocouple Card

I. Overview

The Metso A413345 is an industrial-grade high-density digital I/O module, mainly designed to be compatible with the control systems of Metso crushing and screening equipment (such as jaw crushers, impact crushers, vibrating feeders, etc.). It undertakes the core functions of "on-site switch signal acquisition - control command output - equipment status feedback". Its design focuses on "high reliability" and "ability to resist harsh environments" for heavy-duty industrial scenarios. It adopts a reinforced electrical isolation architecture and a dust-proof and vibration-resistant housing, which can effectively withstand high-frequency vibrations, dust erosion, and electromagnetic interference in crushing workshops. It is widely used in industries that rely on large-scale crushing equipment, such as mining, building materials, and metallurgy.

Compared with general-purpose digital I/O modules, this module features "in-depth compatibility with Metso equipment protocols", "multi-channel high-density integration", and "rapid fault location". It can be directly integrated into Metso C100/C200 series control cabinets, enabling seamless connection with the crusher's main controller, on-site sensors (such as limit switches, proximity switches), and actuators (such as contactors, solenoid valves). This ensures the accurate execution of critical operations such as equipment start-stop and safety interlocking.

III. Functional Features

1. High-Density I/O and Flexible Adaptation

• Multi-Channel Integration: The high-density design with 16 input channels + 8 output channels enables one-stop connection to the crusher's "safety interlock sensors" (such as emergency stop buttons, overload protection switches), "status detection sensors" (such as bearing temperature switches, belt deviation switches), and "actuator control signals" (such as feeder contactors, hydraulic valve solenoid valves). No additional module stacking is required, which greatly simplifies the wiring inside the cabinet;

• Bipolar Input Adaptation: The digital input supports PNP/NPN bipolarity, eliminating the need for manual hardware jumper switching. It is compatible with sensors from mainstream brands such as Omron, Schneider, and Pepperl+Fuchs, reducing the difficulty of on-site selection and replacement, and lowering the pressure of spare parts inventory.

2. Heavy-Duty Industrial-Grade Protection Design

• Triple Electrical Isolation: The power supply, input, and output circuits are isolated from each other (isolation voltage 2500V AC), which can effectively block the interference of surge voltage and electromagnetic radiation generated by the start-stop of the crusher motor on signals. This avoids false triggering of input signals (such as false alarms of "emergency stop activation") or adhesion of output contacts (such as failure to disconnect contactors);

• Reinforced Housing and Vibration-Resistant Structure: The housing is made of flame-retardant ABS material (UL94 V-0 grade). Internal components adopt anti-loosening fixing buckles and buffer rubber pads, which can withstand 3g high-frequency vibration (such as vibration during the operation of vibrating screens) and 15g shock (such as collision during equipment maintenance), making it suitable for harsh working conditions in the mining industry.

3. Convenient Operation & Maintenance and Fault Diagnosis

• Full-Channel Status Indication: 26 LED indicators are installed on the front - power indicator (green, constant on indicates normal power supply), input signal indicators (16 channels, lit indicates signal input in the corresponding channel), output signal indicators (8 channels, lit indicates output activation in the corresponding channel), and communication indicator (red, flashing indicates normal communication). The signal status of each channel can be quickly judged without an oscilloscope or multimeter;

• Fault Self-Diagnosis and Alarm: Equipped with a built-in fault detection circuit. When "power overvoltage/undervoltage", "output short circuit", or "communication interruption" occurs, it will send fault codes to the main controller via RS485 (e.g., E02 indicates power undervoltage, E12 indicates output channel short circuit). At the same time, it triggers the red alarm light to stay on. When used with the Metso TP150 operation panel, the fault location can be directly displayed, shortening the fault location time to the minute level.

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 data interaction among "sensor status - main controller - operation panel" (e.g., displaying the status of each limit switch, remotely controlling the start-stop of feeders);

• Safety Interlock Adaptation: Built-in safety signal processing logic, supporting rapid response to safety interlock signals such as emergency stop and overload (input response time ≤1ms). It complies with the EN ISO 13849-1 safety standard, ensuring the reliability of emergency shutdown of crushing equipment under abnormal working conditions;

• 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 analog modules (such as Metso A413215), enabling modular stacked installation. This reduces space occupation inside the cabinet and lowers the complexity of integration.
