DSRF185 3BSE004282R1 ABB AC410 System Rack
The DSRF185 3BSE004282R1 is a 12-slot I/O rack (cardfile) manufactured by ABB for the Advant OCS / AC410 DCS system. It provides mechanical mounting, backplane bus communication, and power distribution for up to 12 S100 series I/O modules, serving as a core hardware carrier for centralized I/O management in industrial process control
Applications
- Centralized I/O Installation: Accommodates 12 S100 I/O modules (AI/DI/DO/AO) to collect and distribute field signals.
- System Backbone: Acts as the physical and electrical backbone for AC410 controller-based DCS configurations.
- Process Signal Expansion: Extends I/O capacity for large-scale plants, supporting up to 384 process signals based on module types.
- Redundancy Integration: Works with redundant I/O modules to enhance system reliability for critical control loops.
