I. Overview

II. Technical Specifications

1. Electrical & Communication Parameters

• Power Input: Powered stably by a compatible system backplane, it operates normally within a certain voltage fluctuation range to ensure stable performance under different power supply conditions. The specific applicable voltage range complies with general industrial standards, enabling effective compatibility with various industrial power systems.

• Communication Interface: Equipped with an RS-485 interface—widely used in industrial communication for its excellent anti-interference capability and long transmission distance. It supports high-speed data transmission up to 6 Mbaud, enabling fast and accurate data transfer between MTL 8000 nodes and the Profibus-DP master local area network (LAN). This significantly improves data interaction efficiency and meets the strict real-time requirements of industrial automation systems. Meanwhile, the module is fully compatible with the Profibus-DP protocol and strictly adheres to all protocol specifications to ensure reliable and stable data communication.

• Data Capacity: It delivers outstanding performance in data transmission. DP data frames are flexibly configurable, with a maximum size of 244 bytes, allowing it to carry rich data information. Both input data (including status words) and output data (including control words) can reach a maximum of 244 bytes, fully meeting the demand for large-volume data transmission in diverse industrial scenarios. Additionally, diagnostic telegrams are 78 bytes in size; the detailed diagnostic information facilitates timely detection and troubleshooting of system faults, ensuring stable system operation.

2. Isolation & Protection Parameters

• Isolation Performance: Features robust isolation functionality, providing an isolation voltage of 500V between the network interface and internal device circuits. This effectively isolates interference signals from the LAN, external devices, and power supplies, preventing them from affecting the module’s internal precision circuits. As a result, data transmission accuracy and stability are ensured, and data errors or losses caused by interference are avoided.

• ESD Protection: Offers electrostatic discharge (ESD) protection of ±8 kV (air discharge) and ±4 kV (contact discharge), effectively resisting electrostatic interference common in industrial environments. During equipment installation, commissioning, and daily operation, static electricity may damage electronic devices; the module’s high-level ESD protection significantly reduces this risk and enhances equipment reliability and stability.

3. Environmental & Reliability Parameters

• Operating Temperature: Has an operating temperature range of -40°C to 70°C. This wide-temperature design allows the module to adapt to various extreme environments—whether in cold polar regions, hot deserts, or near high-temperature industrial furnaces, it operates normally, ensuring the continuous operation of industrial automation systems under different ambient temperatures.

• Storage Temperature: Features a storage temperature range of -55°C to 85°C. Even when the equipment is unused for an extended period or during transportation, exposure to extreme storage temperatures does not affect the module’s performance or reliability, ensuring equipment availability under complex conditions.

• Relative Humidity: Operates stably in environments with a relative humidity of 5% to 95% (non-condensing) and complies with the IEC 60068-2-38 humidity cycling standard. It maintains fault-free operation after undergoing a rigorous 1,000-hour humidity cycling test, making it reliable for use in high-humidity industrial environments such as coastal chemical plants and humid food processing workshops.

• Electromagnetic Compatibility (EMC): In terms of emissions, it complies with the EN 55022 Class A standard, effectively controlling its electromagnetic radiation to the external environment and reducing interference with surrounding electronic equipment. In terms of immunity, it meets the EN 55024 standard, withstanding interference such as EFT ±2 kV, surge ±4 kV (power port), and RF radiation of 10 V/m. This ensures stable operation and accurate data transmission/processing even in complex electromagnetic environments—such as industrial sites with numerous strong electromagnetic interference sources like motors and frequency converters.

• Mean Time Between Failures (MTBF): Verified through rigorous testing and practical application, it has a long MTBF. It maintains stable and reliable performance during long-term operation, reducing equipment maintenance and downtime, and providing strong support for the continuity of industrial production. Specific values comply with relevant industry standards, demonstrating the module’s high reliability.

4. Compatibility & Installation Parameters

• Compatible Controllers: Perfectly compatible with Eaton’s 8000 series I/O modules and supports various Profibus-DP protocol-compliant master devices (e.g., selected master products from well-known brands like Siemens and ABB). It enables seamless interconnection between devices of different brands, facilitating the construction of diversified industrial automation systems.

• Installation Method: Adopts rack-mounted installation, allowing easy mounting on standard DIN rails. This installation method is not only secure and reliable but also space-efficient, facilitating equipment layout and installation in limited spaces such as industrial control cabinets. Additionally, it supports hot-swapping (requires a hot-swap rack configuration). If a module fails during system operation, it can be replaced directly without shutting down the system, significantly improving system maintenance efficiency and availability.
