AS-B872-200 is a high-performance I/O module under Schneider’s Modicon series, designed for medium to large-scale industrial automation systems. It is mainly used to connect field devices (such as sensors, actuators, and controllers) and realize stable data transmission and signal control, with strong compatibility and environmental adaptability.
- Operating Voltage: 24V DC (typical, suitable for industrial standard low-voltage power supply systems).
- I/O Channels: It is likely to have 16–32 digital input/output channels (specific quantity needs to be confirmed by actual product specifications).
- Communication Protocols: Supports mainstream industrial protocols such as Modbus TCP/IP and Ethernet/IP for fast data interaction with PLCs, HMI, and SCADA systems.
- Operating Temperature Range: -25℃ to +70℃ (can work stably in harsh environments with large temperature fluctuations).
- Protection Rating: IP20 (suitable for indoor control cabinets with controlled dust and humidity, preventing the intrusion of objects larger than 12.5mm).
- Storage Temperature Range: -40℃ to +85℃ (ensures stability during long-term storage or transportation).
-

- High Stability: Equipped with built-in overvoltage, overcurrent, and short-circuit protection functions to avoid damage caused by abnormal field signals, ensuring long-term reliable operation.
- Easy Integration: Adopts a modular design, which can be quickly installed on DIN rails and seamlessly connected with other Modicon series modules (such as power supply modules and communication modules) to reduce system configuration complexity.
- Intelligent Monitoring: May support real-time status feedback (e.g., channel fault alarms, power supply status) to help maintenance personnel quickly locate problems.
- Low Power Consumption: Optimized circuit design reduces energy loss, making it suitable for energy-saving-oriented automation systems (such as water treatment and building automation).
- Installation Method: Supports DIN rail mounting, with a compact structure that saves cabinet space; wiring can be done via prefabricated cables (e.g., Schneider 1492 series cables) to ensure connection reliability.
- Configuration Tool: It can be set and monitored through Schneider’s ACSELERATOR Studio or QuickSet software, including channel parameter adjustment, communication protocol configuration, and fault diagnosis.
- Industrial Manufacturing: Used in production line control (e.g., automobile assembly, electronic component processing) to realize switch control of conveyors, robotic arms, and detection equipment.
- Energy and Utilities: Applied in power distribution systems, water treatment plants, and environmental monitoring stations to collect sensor data and control pumps, valves, and fans.
- Mining and Metallurgy: Adaptable to dusty and vibrating environments, used for equipment status monitoring and process control in mineral processing and smelting links.
