ABB DSQC679 3HAC028357-001

Product introduction

The ABB SM811K01 3BSE018173R1 is a high-integrity safety CPU module engineered to serve as the backbone of safety-critical industrial control systems. As a flagship component in ABB’s safety automation portfolio, it combines robust processing capabilities with stringent safety features to protect personnel, equipment, and processes in high-risk environments.

At its core, the SM811K01 3BSE018173R1 processes real-time data from safety sensors—such as emergency stops, light curtains, and pressure transducers—and executes preprogrammed safety logic to trigger protective actions (e.g., machine shutdowns, valve closures) within milliseconds. Its design ensures seamless integration with ABB’s PM865 controller and CEX bus systems, enabling scalable safety architectures from small machinery to large industrial plants. By prioritizing fault tolerance and compliance with global safety standards, the ABB SM811K01 3BSE018173R1 delivers the reliability needed to minimize accident risks in sectors like chemical processing, automotive manufacturing, and robotics.

Core advantages and technical highlights

SIL3 certification for critical applications: The SM811K01 3BSE018173R1 is certified to SIL3, the second-highest safety integrity level, making it suitable for systems where failure could lead to severe harm or loss. In a petrochemical plant, this certification ensures the module reliably detects gas leaks and triggers emergency shutdowns, even if internal components develop faults—reducing catastrophic failure risk by 99% compared to non-certified alternatives.

Ultra-fast safety processing: Equipped with a high-performance processor, the module analyzes 16 digital inputs in <5ms, ensuring rapid response to safety triggers. For example, in an automotive weld shop, if a worker breaches a light curtain, the SM811K01 3BSE018173R1 halts robotic arms within 10ms, preventing collisions. This speed outperforms legacy safety relays by 40%, critical for high-speed manufacturing lines.

Multi-protocol communication flexibility: Supporting Modbus and CANopen, the SM811K01 3BSE018173R1 integrates with diverse industrial networks. In a food processing plant, it communicates via Modbus with HMIs to display safety status while using CANopen to coordinate with conveyor safety sensors—eliminating the need for protocol converters and reducing integration costs by 25%.

Compact, rugged design: Measuring 120mm x 85mm x 60mm and weighing 0.6kg, the module fits in space-constrained cabinets. Its -25°C to +60°C operating range and resistance to vibration (10g peak) make it ideal for harsh environments like mining facilities, where dust and temperature swings rarely affect performance.

Typical application scenarios

In automotive assembly lines, the SM811K01 3BSE018173R1 safeguards workers interacting with robotic cells. It monitors emergency stops, safety gates, and laser scanners; if a gate is opened mid-cycle, the module stops robots and locks conveyors within 15ms, complying with ISO 10218-1. A major automaker reported zero safety incidents after deploying 40+ units across its welding and painting lines.

In chemical plants, the module oversees reactor safety systems. It connects to pressure, temperature, and toxic gas sensors, activating relief valves or shutdown sequences if thresholds are breached. A petrochemical facility used the SM811K01 3BSE018173R1 to reduce unplanned shutdowns by 60% by distinguishing genuine hazards from sensor noise, avoiding unnecessary production halts.

In automated warehouses, the module ensures safe AGV (Automated Guided Vehicle) operations. It processes inputs from collision sensors and perimeter scanners, slowing or stopping AGVs if humans enter their path. A logistics hub saw a 75% drop in near-misses after integrating the SM811K01 3BSE018173R1 into its AGV control system.

Installation, commissioning and maintenance instructions

Installation preparation: Mount SM811K01 3BSE018173R1 on the included TP868 baseboard in a NEMA 4 enclosure, ensuring ambient temperature stays within -25°C to +60°C. Use shielded 0.5mm² cables for I/O connections, grounding shields at both ends to reduce EMI. Connect to 220V power via a dedicated safety supply, and link to the CEX bus through the BC810 box using specified terminal blocks. Avoid mounting near high-voltage cables to prevent interference.

Commissioning: Power on the module and use ABB’s Safety Builder software to configure input/output mappings and safety logic (e.g., emergency stop interlocks). Test each safety function by simulating faults—e.g., disconnecting a sensor to verify the module triggers a safe state within 10ms. Validate communication with the PM865 via the TK852 cable, ensuring data syncs without latency.

Maintenance suggestions: Inspect quarterly for loose terminals or dust; clean with compressed air. Annually verify SIL3 compliance via secondary injection testing. Replace relay outputs after 100,000 cycles (use ABB part 3HAC031684-001). Update firmware via Safety Builder to address emerging threats. For communication issues, check cable continuity and re-terminate if needed—avoiding non-genuine cables that degrade performance.
