The X20AI8321 is a high-reliability analog input module belonging to B&R’s X20 series, specifically engineered for precise signal acquisition in industrial automation and process control systems. As a core component of B&R’s modular automation ecosystem, it is designed to seamlessly integrate with sensors and control systems, delivering accurate and real-time data support for critical industrial operations. Featuring 8 independent analog input channels, the module supports 0–20 mA and 4–20 mA current signal ranges, covering the most common industrial sensor signal requirements. Equipped with a 12-bit digital converter, it ensures reliable measurement precision, while asynchronous conversion (1 ms interval per channel) enables fast response to signal changes—ideal for real-time applications like high-speed production lines and automated detection systems. The module incorporates 500 VDC galvanic isolation between channels and the bus, enhancing anti-interference capability in complex industrial environments. Designed for easy integration, the X20AI8321 utilizes the X2X Link communication protocol, enabling seamless connection with B&R X20 series controllers, bus modules (e.g., X20BM11), and terminal blocks (e.g., X20TB1F). It supports configuration via B&R Automation Studio software, allowing users to customize input filters, channel parameters, and limit values to match specific application needs. Industrial-grade reliability is ensured through an IP20 protection rating, operation across a wide temperature range (-25°C to 60°C for horizontal mounting), and compliance with international standards including CE, UL, and ATEX Zone 2 certifications. Complemented by comprehensive diagnostic functions—including LED status indicators for channel and module health, plus software-accessible fault monitoring—the module simplifies troubleshooting and maintenance. Its compact rail-mounted design optimizes cabinet space, while robust construction resists electromagnetic interference and mechanical vibration, making it suitable for diverse industrial scenarios such as manufacturing lines, process control, energy management, and automated testing systems. Whether for new system builds or existing system upgrades, the X20AI8321 delivers consistent performance, flexibility, and compatibility to support efficient industrial operations. |
