ABB DSRF182AK02 3BSE014078R1 Redundant I/O Module Rack
The DSRF182AK02 3BSE014078R1 is a redundant I/O baseplate/ subrack manufactured by ABB for the AC 800M DCS system. It serves as a dual-module carrier, supporting 1:1 redundancy for S800 series I/O modules, ensuring high availability and fault tolerance in critical process control applications.
Applications
- Redundant I/O Installation: Accommodates two identical S800 I/O modules (AI/DI/DO/AO) for automatic failover.
- High-Availability Control: Ensures uninterrupted operation of critical loops in power, chemical, and oil & gas plants.
- Hot-Swap Support: Enables online replacement of faulty modules without system shutdown.
- System Expansion: Extends I/O capacity for AC 800M controllers in large-scale process systems.
