Overview
The ABB SM811K01 Safety Controller Module is a high-integrity CPU engineered for safety-critical applications requiring SIL3 compliance. Operating within the AC 800M High Integrity control system, it works in tandem with the PM865 controller to establish a redundant, fault-tolerant architecture for process safety applications.
Moreover, the SM811K01 continuously monitors the PM865 processor and executes safety logic independently, ensuring rapid fault detection and safe process shutdown when necessary. In addition, it supports hot-swap capability and redundant configurations, minimizing downtime during maintenance or system failures. Therefore, it is ideal for Emergency Shutdown (ESD), Burner Management (BMS), and Safety Instrumented Functions (SIFs) across the oil & gas, petrochemical, and power generation industries.
The module is delivered as a complete kit — including the SM811 CPU, TP868 baseplate, and TK852V10 synchronization cable for simplified installation and integration.

Typical Applications
Emergency Shutdown Systems (ESD)
Executes independent safety logic to perform rapid process shutdowns during hazardous or fault conditions.
Burner Management Systems (BMS)
Ensures safe burner startup, operation, and shutdown to prevent fuel or ignition faults.
High-Integrity Pressure Protection Systems (HIPPS)
Provides real-time overpressure protection and safety interlocking in oil & gas operations.
Turbine and Boiler Safety Control
Monitors critical process parameters and initiates controlled shutdowns in power generation environments.
Example:
In a petrochemical plant, the SM811K01 reduced unplanned outages by 90% through real-time fault detection and redundant logic execution, improving both safety and uptime.
FAQ
Q: What makes the SM811K01 suitable for SIL3 applications?
A: It is certified to IEC 61508 SIL3 and operates independently from the main controller, ensuring process safety even in the event of a system fault.
Q: Can it be used in redundant configurations?
A: Yes, it supports hot-standby redundancy when paired with the PM865 controller and BC810 bus interconnection.
Q: Is the module RoHS compliant?
A: No, it is not compliant with RoHS 2 (2011/65/EU), as stated in ABB documentation.
Q: What’s included in the SM811K01 kit?
A: The kit includes the SM811 CPU, TP868 baseplate, and TK852V10 synchronization cable.
Q: Is it compatible with standard AC 800M controllers?
A: It is specifically designed for the AC 800M High Integrity system and operates in conjunction with the PM865 controller for safety-certified functions.
