ABB PU515A 3BSE032401R1 Real-Time Accelerator (RTA) PCI Control Board

Product Description

PU515A (3BSE032401R1) is ABB Real-Time Accelerator PCI board, core hardware component for classic Advant OCS distributed control system.

It undertakes high-speed real-time data processing, fieldbus signal scheduling and closed-loop control algorithm acceleration, relieves host CPU computing burden. Equipped with dual D-Sub serial 

communication interfaces, onboard memory and dedicated real-time processing chip, conformal coated PCB, standard PCI slot installation inside Advant controller industrial computer. 

It is an obsolete critical replacement spare for power plant, pulp & paper, metallurgy legacy ABB DCS control rooms.

Key Features

Independent real-time acceleration processor ensures high deterministic control cycle for critical process regulation loops.

Offloads heavy control computation tasks from host computer, avoids system delay caused by multi-task resource competition.

Dual serial communication channels realize stable data exchange with field I/O stations and peripheral control units.

Built-in hardware fault monitoring circuit, detects board communication abnormality and outputs system alarm signal.

Conformal coated circuit board resists dust, humidity and vibration in long-term continuous running control room environment.

Standard PCI mechanical structure, supports direct one-to-one replacement for same part number PU515A modules.

Mature hardware architecture widely deployed in old generation Advant OCS DCS for power and process industry.

Supports real-time data logging, event sequence processing and continuous closed-loop process control.
