Description

RTAC-01-A: Product Overview
The RTAC-01-A is a ruggedized industrial computer and real-time automation controller from ABB, designed to bridge the gap between traditional PLC/DCS control and IT systems. This device functions as a versatile platform for a wide range of industrial applications, including data concentration, protocol conversion, advanced control algorithms, and edge computing. It operates as a standalone controller or a data gateway, acquiring information from various industrial devices via multiple communication protocols, processing the data using custom logic or pre-built functions, and distributing it to higher-level systems such as HMIs, historians, or enterprise platforms.
The controller runs a deterministic real-time operating system (typically a hardened Windows Embedded platform) alongside ABB’s control engine, ensuring reliable and predictable execution of control tasks. Its x86-based architecture provides the computational power to handle complex mathematical calculations, data logging, and communication tasks that are often challenging for conventional PLCs. The unit is housed in a robust, fanless enclosure designed for continuous operation in harsh industrial environments, with wide temperature tolerance and immunity to electrical noise and vibration.

Core Features & Customer Value
The primary value of the RTAC-01-A is its unparalleled flexibility and connectivity. It can communicate with virtually any modern or legacy industrial device, acting as a universal protocol translator. This allows plants to integrate equipment from different vendors and of different vintages into a cohesive system without requiring expensive hardware upgrades. For system integrators, this drastically reduces the complexity and cost of modernization projects.
Its processing power enables the implementation of advanced applications directly at the edge, such as mathematical modeling, predictive analytics, and complex sequencing logic. This offloads computational burden from higher-level systems and allows for faster, localized decision-making. For users, this translates to improved process optimization, energy efficiency, and asset performance management based on richer data analysis.
Typical Applications
In electrical substation automation, the RTAC-01-A is widely used as a gateway and controller. It collects data from intelligent electronic devices (IEDs) using protocols like IEC 61850 and DNP3, performs load balancing and interlocking logic, and streams data to a SCADA system. Its rugged design is essential for the uncontrolled environments of switchgear rooms.
In water/wastewater treatment, it performs as a data concentrator for multiple PLCs spread across a large site, unifying data from various brands of controllers before sending it to a central SCADA. It can also run advanced control algorithms, like optimizing chemical feed rates based on real-time water quality analytics.
