The protection of people, processes and the surrounding environment remain a significant part of an automation strategy for any industry. We offer solutions to help meet your process safety standards that are as varied as each of your environments. You can expect us to engage the right dedicated resources to design, implement, and deploy a complete process safety solution. Plus, our architectures support fault tolerance for system components and scalable options including fail-safe, fault-tolerant, and triple modular redundancy (TMR).
What is a Safety Instrumented Systems (SIS)?
A safety instrumented system (SIS) is an independent layer of protection designed to automatically detect hazardous conditions and take corrective action to prevent or mitigate serious incidents in industrial operations. It uses sensors to monitor critical process variables, logic solvers to evaluate risk conditions and final control elements—such as valves or shutdown systems—to move the process to a safe state when predefined limits are exceeded. SIS solutions are commonly used in high-risk environments like oil and gas, chemicals and manufacturing to protect people, equipment and the environment while helping organizations meet regulatory and safety integrity requirements.
Benefits of Safety Instrumented Systems
A safety instrumented system delivers critical protection for high-risk industrial processes by reducing the likelihood and impact of dangerous events, offering the following key benefits:
- Protects people, equipment and the environment by preventing or mitigating hazardous events
- Automatically detects unsafe conditions and initiates rapid, reliable responses
- Reduces the risk of major incidents, downtime and unplanned shutdowns
- Provides an independent layer of protection separate from basic process control systems
- Helps organizations meet regulatory, compliance and safety integrity requirements
- Improves operational reliability and confidence in high-risk processes
- Supports consistent, repeatable safety performance across facilities
Logix SIS
Highly Available Fail-Safe Control System
Logix SIS is a centralized modernized fail-safe control system with the latest hardware and software, providing a simplified approach for ease of implementation. Up to SIL 3 fail-safe architectures are achievable with future enhancements expected with each new release of Logix.
AADvance Control System
Scalable Fault-Tolerant Control Systems
Process safety applications often require multiple SIL levels: from SIL 1 through SIL 3 in the same control strategy. You need a cost-effective system that can be scaled to meet these requirements. Our AADvance® control system delivers unparalleled performance and value as well as a truly distributed process safety architecture.
Trusted Control System
SIL 3 for Large Process Safety Systems
Trusted® is a triple modular redundant controller designed to provide maximum safety and availability in all circumstances. Trusted incorporates a fault-tolerant architecture to virtually eliminate spurious system trips and provides high availability as part of its inherent safety-related functionality.
ControlLogix SIL 2
Safety Configured Controller Solutions
The ControlLogix® SIL 2 solution provides very high levels of availability for those SIL 2 basic process control system and/or process safety system applications that cannot tolerate a system shutdown.
