Product Overview
The GE IS215UCVEH2AF is a Triple Modular Redundant(TMR)safety controller module engineered for the GE Mark VIeS platform—a dedicated safety and shutdown system derived from the proven Mark VIe architecture.Unlike standard control modules,the IS215UCVEH2AF is designed and certified to SIL 3 under IEC 61508,making it suitable for the most critical safety functions in oil&gas,refining,power generation,and chemical processing—such as turbine overspeed protection,emergency shutdown(ESD),burner management(BMS),and fire&gas(F&G)response.
At its core,the IS215UCVEH2AF implements three independent processing lanes that continuously execute identical safety logic and vote on outputs.If one lane fails or diverges,the other two override it—ensuring fail-safe operation without spurious trips.The module communicates over redundant SafetyNET networks to I/O modules(e.g.,IS215 series)and integrates seamlessly with the main Mark VIe control system for coordinated startup,monitoring,and diagnostics.With built-in self-tests,redundant power inputs,and secure firmware validation,the IS215UCVEH2AF delivers the highest level of functional safety while simplifying compliance with global standards like API 670,NFPA 85,and IEC 61511.

Main Features and Advantages
True TMR Architecture for Maximum Safety Availability
The IS215UCVEH2AF employs hardware-level redundancy:three CPUs,three memory sets,and three communication paths operate in parallel.Continuous cross-comparison and voting eliminate single-point failures—critical for applications where an unsafe failure could result in fire,explosion,or environmental release.
Deterministic Safety Response(<10 ms typical)
From sensor input to trip output,the Mark VIeS system—including the IS215UCVEH2AF—delivers sub-10-millisecond response times.This speed is essential for turbine overspeed trips(e.g.,110%speed detection),where milliseconds determine between controlled shutdown and catastrophic mechanical failure.
Seamless Integration with Process Control
While functionally independent for safety integrity,the IS215UCVEH2AF shares engineering tools(ToolboxST)and can exchange data with the main Mark VIe via secure gateways.This allows operators to view safety status alongside process variables—improving situational awareness without compromising separation of duties.
Comprehensive Diagnostics&Cybersecurity
Built-in online diagnostics monitor CPU health,memory integrity,and network sync.All firmware is cryptographically signed to prevent unauthorized modifications.Access control,audit logging,and secure boot align with IEC 62443 and NERC CIP requirements.
Certified for Global Safety Standards
The IS215UCVEH2AF is pre-certified for API 670(machinery protection),NFPA 85(boiler safety),and IEC 61511(process industry SIS),reducing project risk and accelerating regulatory approval in demanding jurisdictions.
Application Field
The IS215UCVEH2AF is deployed wherever human life,environmental safety,or high-value assets demand the highest level of automated protection:
Gas Compression Stations:Turbine overspeed,lube oil pressure loss,and vibration trips.
Refineries&Petrochemical Plants:Emergency depressurization(EDP),reactor temperature limits,and F&G system actuation.
Combined-Cycle Power Plants:Boiler furnace pressure protection(NFPA 85),steam turbine ESD,and generator breaker interlocks.
LNG Facilities:Cryogenic pump shutdown,tank overfill prevention,and vapor cloud detection response.
Offshore Platforms:Integrated platform-wide ESD triggered by fire,gas leak,or process excursion.
In each case,the IS215UCVEH2AF ensures that safety actions are executed reliably—even during cyberattacks,component aging,or extreme environmental stress.

Installation and Maintenance
Installation Guidance:
Install the IS215UCVEH2AF only in a certified Mark VIeS rack with proper grounding and dual 24 VDC power supplies.Maintain physical and logical separation from non-safety circuits per IEC 61511.Use shielded cables for all field connections,with shields grounded at the controller end.Perform loop checks using ToolboxST before enabling safety logic.
Maintenance Best Practices:
Conduct periodic proof tests per the Safety Requirements Specification(SRS).
Review diagnostic logs monthly for early signs of degradation(e.g.,memory errors,sync faults).
Never bypass safety outputs without formal management-of-change(MOC)approval.
Firmware updates must be performed using authenticated SAB sessions with version rollback capability.
Replace the module if any lane reports persistent faults or fails built-in diagnostics.
Product Guarantee
Each IS215UCVEH2AF undergoes rigorous factory testing for functional safety performance,including fault injection and voting logic validation.We provide a 24-month warranty and guarantee compliance with stated SIL 3 certification requirements when installed and maintained per GE documentation.Backed by decades of leadership in industrial safety systems,GE ensures the IS215UCVEH2AF delivers uncompromising reliability—because in functional safety,there are no second chances.
