ABB DSRF197 3BSE019297R1 | S800 I/O Equipment Frame (Rack/Chassis)

ABB DSRF197 3BSE019297R1 is a redundant I/O equipment frame (rack/chassis) for ABB AC 800M controllers (800xA DCS). It provides mechanical mounting, dual redundant backplane wiring, and power distribution for S800 I/O modules, serving as the core hardware carrier for high-availability industrial control systems.
Key Features

• Redundant I/O Frame Design: 19-inch 2U rack chassis with dual backplane for fault-tolerant I/O operation.
• 8-Slot Module Housing: Accommodates up to 8 S800 I/O modules (AI810, AO810, DI810, DO810).
• Industrial-Grade Construction: Heavy-duty metal frame for vibration resistance; IP20 front protection.
• Hot-Swap & Online Maintenance: Supports live module replacement without system shutdown.
• Integrated Backplane & Wiring: Dual signal paths and power distribution for redundant control.
• Seamless AC 800M Compatibility: Matches PM860/PM861/PM862 controllers in 800xA systems.
