Description
Product Overview
The ABB L003748-AR 3BSX108237R300 is a high-performance processor board from ABB’s AC 700F safety controller series, a critical component of the Freelance distributed control system (DCS). This module is a standalone, powerful CPU designed for integrated standard and safety instrumented system (SIS) control, enabling the consolidation of basic process control system (BPCS) and safety functions within a single, cohesive platform. The L003748-AR 3BSX108237R300 executes application logic, manages communication, and processes I/O data with SIL 2/SIL 3 capability according to IEC 61508 and IEC 61511 standards. It is engineered for demanding process automation applications where functional safety, high availability, and seamless engineering integration are essential. Integrating this processor into your architecture provides a unified engineering environment, simplifying system design, operation, and maintenance while achieving rigorous safety certifications.
