Description
ABB SD821: High-Speed PROFINET/PROFIBUS DP Communication Module for Industrial Control Systems
Product Overview
The ABB SD821 is a high-performance dual-protocol communication module designed for seamless integration of industrial automation systems. As part of ABB’s AC800M modular control platform, this module supports PROFINET IO RT and PROFIBUS DP V1, enabling real-time data exchange between field devices (e.g., sensors, actuators) and centralized controllers. With dual-port redundancy and hot-swap capabilities, the SD821 ensures continuous operation in mission-critical environments, such as chemical plants, power generation facilities, and smart manufacturing lines.
Engineered for reliability, the SD821 features a 32-bit ARM Cortex-M4 processor (400 MHz) and 64 MB RAM + 128 MB flash memory, delivering low-latency data processing and robust protocol handling. Its IP20-rated enclosure and EMI shielding (reducing interference by 30%) ensure stable performance in high-noise industrial settings. The module integrates seamlessly with ABB’s Advant OCS and Industrial IT systems, supporting OPC UA for cloud-based analytics and predictive maintenance.
