Process Safety Solution – Honeywell FC-TSDI-16UNI | Safety Manager Safe Digital Input FTA
Where This Product Is Used
The Honeywell FC-TSDI-16UNI is a 16-channel universal Safe Digital Input Field Termination Assembly (FTA) designed for use within Honeywell’s Safety Manager and Experion Safety Instrumented System (SIS) platforms. It is deployed in safety-critical environments where reliable detection of discrete field signals is essential for process shutdown and emergency response.
Typical application sites include:
- Oil & Gas Upstream/Midstream: Wellhead ESD panels, pipeline leak detection, compressor station safety loops
- LNG & Petrochemical Plants: High-integrity pressure protection systems (HIPPS), burner management systems (BMS)
- Refinery Operations: Reactor trip systems, fired heater safety interlocks
- Chemical Manufacturing: Toxic gas detection voting logic, emergency depressurization triggers
- Power Generation: Turbine overspeed protection, boiler safety shutdown loops
- Offshore Platforms: Fire & gas detection integration, process shutdown (PSD) systems

Application-Specific FAQ
Q: Is the FC-TSDI-16UNI compatible with Honeywell Experion PKS as well as Safety Manager?
A: The FC-TSDI-16UNI is a Safety Manager FTA and interfaces with the Safety Manager logic solver. It is not a direct Experion PKS I/O module, but Safety Manager integrates with Experion PKS via the Safety Builder / FTE network in a unified SIS architecture.
Q: Can this FTA be used in SIL 3 applications?
A: The FC-TSDI-16UNI is rated for SIL 2. SIL 3 applications require redundant voting architectures (e.g., 2oo3 configurations). Consult your functional safety engineer and Honeywell’s SIL data package before specifying for SIL 3 loops.
Q: What is the difference between FC-TSDI-16UNI and other Honeywell digital input FTAs?
A: The “UNI” designation indicates universal input capability, accepting both wet and dry contacts as well as NAMUR sensors without additional hardware. Other variants may be optimized for specific input types or voltage ranges.
Q: Do you supply the FTA cable separately?
A: Yes. Please specify the required cable length when requesting a quotation. We can supply the complete FTA-to-module cable assembly.
Q: Can Konmask provide a full Safety Manager spare parts kit?
A: Yes. We specialize in complete SIS spare parts packages for Honeywell Safety Manager systems. Contact us with your system configuration for a tailored spare parts list and pricing.
