Process Safety & Control Solution — ICS Triplex T3401 | Trusted TMR Series
Where This Product Is Used
The ICS Triplex T3401 24 VDC Digital Input Module is purpose-built for Safety Instrumented Systems (SIS) and Triple Modular Redundant (TMR) control architectures in the most demanding industrial environments. Engineers specify this module in:
- Oil & Gas — Upstream & Midstream: Emergency Shutdown (ESD) systems on wellheads, compressor stations, and pipeline SCADA nodes where SIL 2/3 integrity is mandatory.
- Offshore Platforms & FPSOs: Fire & Gas (F&G) detection panels and process shutdown logic where single-point failure is unacceptable.
- Petrochemical & Refinery Plants: Burner Management Systems (BMS), high-integrity pressure protection (HIPPS), and reactor interlock loops.
- Power Generation: Turbine protection, boiler safety, and grid-tie interlock circuits requiring deterministic digital input scanning.
- Chemical & Pharmaceutical Manufacturing: Batch reactor safety loops and critical valve position monitoring under IEC 61511 compliance.
- Water & Wastewater Treatment: Pump protection and overflow prevention systems with redundant I/O requirements.

Why Engineers Specify This Model
- TMR Redundancy: Three independent input channels vote 2-out-of-3, eliminating single-point failures and enabling fault-tolerant operation without spurious trips.
- Online Replacement: Hot-swap capability allows module replacement during live plant operation — critical for continuous-process industries with zero planned downtime.
- Deterministic Scan Time: Consistent, predictable input scanning ensures safety logic executes within defined response windows required by functional safety standards.
- Continuous Diagnostics: Built-in self-test routines detect wiring faults, open circuits, and module degradation before they impact process safety.
- Long Field Life: Designed for 20+ year plant lifecycles; spare modules are essential for sustaining legacy Trusted TMR installations.
- Proven Global Installed Base: Deployed across hundreds of SIS installations worldwide in oil & gas, power, and chemical sectors.

Application-Specific FAQ
Q: Is the T3401 compatible with all Trusted TMR chassis generations?
A: The T3401 is designed for the ICS Triplex Trusted TMR platform. Compatibility depends on chassis revision and firmware version. Provide your chassis model number and we will confirm fit before shipment.
Q: Can this module be used in SIL 3 applications?
A: Yes. The Trusted TMR architecture with 2oo3 voting logic supports SIL 3 loop integrity when properly configured per IEC 61508/61511 requirements. Consult your functional safety engineer for loop SIL verification.
Q: What is the lead time if the module is not in stock?
A: Typical sourcing lead time for de-installed or refurbished units is 5–15 business days. New OEM stock lead times vary. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes. All modules sold by Konmask.com carry a minimum 12-month warranty against functional defects. Extended warranty options are available on request.
Q: Can you supply the full Trusted TMR system, not just individual modules?
A: Yes. We supply complete Trusted TMR system assemblies, individual I/O modules, processors, power supplies, and FTAs. Send your full BOM to [email protected].
