Description
ABB PU515A Real-Time Accelerator (RTA) Board
The PU515A is a high-performance real-time accelerator (RTA) board designed by ABB for industrial automation systems, delivering advanced computational power and seamless integration with ABB’s Advant OCS and System 800xA platforms. Engineered to offload critical processing tasks from the main CPU, the PU515A enhances system responsiveness and control precision in demanding environments such as manufacturing, energy, and infrastructure.
1. Product Overview
The PU515A serves as a PCI interface card for real-time data processing, supporting MB300 protocol communication and dual-channel architecture to optimize control logic execution. With 16 MB of RAM and a 25 MHz CPU, it accelerates tasks like closed-loop control, data acquisition, and safety-related applications, ensuring minimal latency (<10 ms response time) in time-sensitive operations. Its -25°C to +70°C operating temperature range and IP20-rated housing make it suitable for harsh industrial conditions.
