Description

Product Overview
The ​ABB CI546 3BSE012545R1 is an industrial-grade ​Foundation Fieldbus HSE (High-Speed Ethernet) interface module for ABB’s AC 800M control system, designed to bridge high-level process automation with field-level instrumentation. As a critical component of ABB’s 800xA Extended Automation platform, the ​CI546 3BSE012545R1 enables deterministic communication (≤500 µs latency) with Fieldbus devices while supporting IEC 61804-3/EITF functionality block standardization. Its dual-redundant 100 Mbps Ethernet ports ensure continuous data exchange for real-time control loops, diagnostics, and asset management across refineries, chemical plants, and power generation facilities. With integrated Link Active Scheduler (LAS) capabilities and SIL 2 certification (IEC 61508), this module maintains operational integrity in explosive atmospheres (ATEX Zone 2) and harsh environments (-40°C to +70°C).
