Product Overview
The Honeywell FC-TSAI-1620M functions as a high-integrity Field Termination Assembly (FTA) designed for the Honeywell Safety Manager and Experion PKS platforms. This module provides 16 channels of precise analog signal conditioning, acting as the critical interface between field transmitters (pressure, flow, temperature) and the SAI-1620m safety module. Engineered for mission-critical safety instrumented systems (SIS), it ensures 0.1% accuracy for high-reliability process monitoring. We provide this unit as 100% Brand New and Original to meet the stringent requirements of certified safety loops.

Engineering Advantages
-
SIL3 Certified Safety Path: This FTA meets TÜV SIL3 requirements, making it suitable for Emergency Shutdown (ESD) and Fire and Gas (F&G) systems. It maintains signal integrity in environments where failure is not an option.
-
Dual-Transmitter Support: The module interfaces with both active and passive transmitters. It provides up to 120 mA at 30 VDC to power passive loops, eliminating the need for separate field power distribution hardware.
-
Precision Signal Mapping: The unit converts 0–20 mA field signals into a highly accurate 0–4 VDC output for the SAI-1620m module. This 0.1% accuracy ensures that safety logic executes based on the most precise data available.
-
Robust Circuit Protection: Each channel features a 315 mAT slow-acting fuse. This protection isolates field wiring faults, preventing short circuits from damaging the centralized safety controller or neighboring input channels.
-
Simplified Field Wiring: High-density screw terminals accommodate wire diameters up to 2.5 mm² (AWG 14). The organized layout reduces cabinet clutter and accelerates commissioning during plant turnarounds.
-
Industrial Durability: Standard conformal coating protects the PCB against moisture and corrosive atmospheric pollutants, ensuring a long service life in harsh refinery and chemical plant conditions.
FAQs
1. How does the FC-TSAI-1620M handle passive field transmitters?
The FTA includes current-limiting circuitry that supplies up to 120 mA to passive transmitters. This internal power distribution simplifies your cabinet architecture by removing the requirement for external power rails for 2-wire loops.
2. Is the FC-TSAI-1620M compatible with non-safety Experion PKS systems?
While designed primarily for the Honeywell Safety Manager (SIL3), it integrates with Experion PKS environments that utilize Safety Manager controllers for high-reliability process monitoring and control.
3. What maintenance is required for the input fuses?
The module utilizes standard 315 mAT slow-acting 5 x 20 mm fuses. You can easily access and replace these fuses on the FTA without removing the entire assembly from the DIN rail, minimizing maintenance downtime.
4. Does this module come with a certificate of authenticity?
We supply the FC-TSAI-1620M as 100% New and Original in factory-sealed packaging. Each unit complies with Honeywell’s rigorous manufacturing standards for safety-rated hardware and includes a standard 12-month warranty.
