Your industrial plant thrives on safety and reliability. A single process failure can trigger shutdowns, cost millions, or endanger lives.

A safety instrumented system (SIS) is your plant’s protector; neutralizing risks before they escalate. Proconex delivers Emerson’s DeltaV SIS to ensure operational excellence in industries like chemical, refining, oil & gas, life sciences, and power generation. Let’s explore what a safety instrumented system does; why it’s vital; and how our solutions keep your plant secure.

What is a Safety Instrumented System?

A safety instrumented system is a specialized system for industrial facilities, designed to handle emergencies; detecting hazards like gas leaks or pressure surges and acting to prevent disasters. It’s a fail-safe system; built to comply with IEC 61511 standards; using sensors, logic solvers, and actuators to bring processes to a safe state. In addition, SIS reduces incident risks by 60 percent; making a safety instrumented system critical for high-hazard plants.

DeltaV SIS Integration; for instance; operates independently from your main controls; ensuring reliability. If a reactor overheats; it shuts down the process or opens a valve in milliseconds; no human needed. This precision keeps your plant safe; compliant; and productive. SIS also integrates with existing systems; providing a unified view of safety and operations; enhancing decision-making across your facility.

Why Safety Instrumented Systems are Essential

Your plant deals with volatile processes daily; high pressures, flammable gases, or extreme temperatures. Without a safety instrumented system; a glitch could spark catastrophe. The SIS market will hit $4.5 billion by 2028; driven by safety demands. Here’s why SIS is non-negotiable:

  • Prevent Disasters: SIS cuts major incident risks by 60 percent.
  • Reduce Downtime: Avoid shutdowns to save 30 percent on outage costs.
  • Ensure Compliance: Meet IEC 61511 and ISA 84 standards; dodging fines.
  • Protect Workers: Keep hazardous processes safe; reducing workplace risks.

Plants using DeltaV SIS; supplied by Proconex; see fewer safety events; aligning with industry goals for zero-incident operations. SIS also supports environmental compliance; preventing spills or emissions; crucial for regulatory bodies like the EPA.

Key Features of DeltaV SIS

Proconex’s safety instrumented system; the Emerson DeltaV SIS; is engineered for reliability and efficiency. Here’s what makes it stand out:

  • Integrated Yet Independent Architecture: Syncs with DeltaV DCS for unified control; remains separate to meet IEC 61511/ISA 84; reducing complexity.
  • Certified SIL3 Capabilities: Handles critical SIL3 tasks in chemical or refining; ensuring safety in high-risk settings.
  • Modular and Scalable Design: Fits small or sprawling plants; scales seamlessly as you grow.
  • Electronic Marshalling and CHARMs Technology: CHARMs simplify wiring; cut commissioning time by 50 percent.
  • Built-In Diagnostics and Predictive Intelligence: Detects issues early; reduces downtime by 25 percent.
  • Cybersecurity-Ready Infrastructure: Offers secure access, encrypted data, and audit trails; safeguarding your system.
  • Lifecycle Management Tools: Proconex provides FEED studies, SIL verification, and ongoing testing; ensuring long-term compliance.

These features make DeltaV SIS a top choice; blending safety with operational smarts.
