METSO IOP303 RTD Input Module

• High-precision Temperature Acquisition: It supports the input of various standard RTD types such as Pt100 and Pt1000. Using high-precision A/D conversion technology, the temperature measurement accuracy reaches ±0.1℃ (typical value), which can accurately capture temperature changes and meet the strict requirements of industrial-grade temperature monitoring.​

• Linearization Compensation and Filtering: The built-in linearization algorithm automatically compensates for the non-linear characteristics of RTDs, ensuring accurate measurement results. It also has a digital filtering function, which can effectively suppress signal noise interference and output smooth and stable temperature data.​

• Electrical Isolation Protection: Each input channel adopts isolation technology with an isolation voltage of up to 1500Vrms. It can effectively isolate electrical interference, surges, and ground loops between field devices and the control system, ensuring the stable operation of the system.​

• Fault Diagnosis and Alarm: It continuously monitors faults such as RTD disconnection, short circuit, and out-of-range. When an abnormality occurs, it alarms through LED indicator lights and outputs fault codes, enabling maintenance personnel to quickly locate and resolve problems.​

• Input Channels: It has [X] independent RTD input channels, supporting parallel acquisition to monitor multiple temperature points simultaneously.​

• RTD Types: It supports various RTDs such as Pt100, Pt1000, Ni100, and Ni1000, and is compatible with 2-wire, 3-wire, and 4-wire connection methods.​

• Communication Interface: Equipped with communication interfaces such as Profibus DP and Modbus RTU, it supports fast communication with control systems like PLCs and DCSs, enabling real-time upload of temperature data and remote configuration.​

• Power Supply: 24V DC ±15%, with overvoltage, overcurrent, and reverse connection protection functions. It has low power consumption and stable operation.​

• Working Environment: The operating temperature range is -40°C - 70°C, and the storage temperature is -40°C - 85°C; the protection level is IP20, allowing it to adapt to harsh industrial environments.​

• High Precision and Stability: Using high-quality components and precise circuit design, and through strict testing and calibration, the Mean Time Between Failures (MTBF) exceeds 200,000 hours, ensuring long-term stable and accurate temperature data collection.​

• Convenient Installation and Maintenance: Adopting the standard 35mm DIN rail installation, it has a compact structure, and installation and removal are convenient. It supports hot-swappable operation, allowing module replacement without system shutdown. The module is equipped with intuitive status indicator lights, facilitating quick checking of the operation status and fault information.​

• Flexible Expandability: Channel parameters can be flexibly configured according to actual needs. It supports cascading multiple modules, easily expanding the number of temperature monitoring points to meet the requirements of industrial projects of different scales.​

• Strong Compatibility: It can be seamlessly integrated into automation control systems of METSO and other mainstream brands, adapting to a variety of industrial automation application scenarios.​

• Petrochemical Industry: It is used to monitor the temperature of equipment such as reactors, pipelines, and storage tanks, ensuring the safe and stable operation of the chemical production process.​

• Power Industry: In power plants, it monitors the temperature of key equipment such as generators, transformers, and cables, preventing equipment overheating failures and ensuring the reliable power supply of the power system.​

• Food and Beverage Industry: It precisely controls the temperature during production, storage, and transportation, ensuring product quality and safety and meeting industry hygiene standards.​
