ICS TRIPLEX T7411 – High-Integrity Pressure Transmitter | TMR Safety Platform
Engineering Background
The ICS TRIPLEX T7411 is a high-integrity pressure transmitter engineered for safety-critical process measurement within ICS Triplex’s proven Triple Modular Redundant (TMR) architecture. Designed to meet the stringent demands of SIL 2/3 certified safety instrumented systems (SIS), the T7411 delivers continuous, fault-tolerant pressure monitoring across the harshest industrial environments. It is a direct-fit replacement and expansion module for legacy and current-generation ICS Triplex safety platforms.
Product Positioning
Targeted at instrumentation engineers and reliability teams in oil & gas, petrochemical, power generation, and offshore processing facilities, the T7411 eliminates single-point-of-failure risk in pressure measurement loops. Its TMR voting logic ensures uninterrupted process control even during partial sensor degradation, making it the preferred choice for emergency shutdown (ESD) and fire & gas (F&G) system integrations.

Proven Application Environments
- Oil & Gas: Wellhead pressure monitoring, pipeline ESD loops, separator vessel control
- Petrochemical & Refining: Reactor pressure safety, distillation column instrumentation
- Power Generation: Boiler drum pressure, turbine lube oil pressure SIS
- Offshore Platforms: Subsea topsides pressure measurement in F&G systems
- LNG & Terminal Facilities: Cryogenic process pressure monitoring with SIL-rated loops
Engineering Advantages
- Fault Tolerance by Design: TMR 2oo3 voting architecture maintains output integrity even with one channel failed — no spurious trips, no dangerous undetected failures.
- Continuous Diagnostics: Built-in self-test routines detect sensor drift, open-circuit, and short-circuit conditions without process interruption.
- HART Transparency: Full HART pass-through enables field device configuration and diagnostics from the control room without loop isolation.
- Hot-Swap Capable: Module replacement under power (chassis-dependent) minimizes maintenance downtime in live process environments.
- Long Service Life: Designed for 10+ year operational cycles consistent with ICS Triplex platform lifecycle commitments.
System Architecture & Signal Flow
The T7411 interfaces directly with field-mounted 4–20 mA pressure transmitters via HART-enabled wiring. Each of the three redundant input channels independently conditions and digitizes the analog signal. The TMR controller’s 2oo3 voting logic compares all three channel values in real time — a discrepancy beyond the configured deviation band triggers a diagnostic alarm while maintaining the voted output to the process control system. This architecture satisfies IEC 61511 requirements for SIS pressure measurement loops without additional external voting hardware.
