ABB DSRF197 3BSE019297R1 16 slot high-density I/O rack
The DSRF197 3BSE019297R1 is a 16‑slot high‑density I/O rack designed by ABB for the AC 800M/800xA DCS platform. It provides mechanical mounting, backplane communication, and power distribution for up to 16 S800 series I/O modules, serving as a core hardware carrier for large‑scale, high‑density process control I/O configurations.
Applications
- High‑Density I/O Installation: Accommodates 16 S800 I/O modules (AI/DI/DO/AO) to centralize field signal collection and distribution.
- System Backbone for AC 800M: Acts as the physical and electrical foundation for AC 800M controller‑based DCS configurations.
- Large‑Scale Process Expansion: Extends I/O capacity for large plants, supporting up to 512 process signals based on module types.
- Redundancy Integration: Works with redundant S800 modules to enhance reliability for critical control loops.
- Hot‑Swap Maintenance: Supports online module replacement without system shutdown, minimizing downtime.
