Product Overview

The Honeywell FC-TSAI-1620M serves as the high-integrity Field Termination Assembly (FTA) specifically designed for the Honeywell Fail-Safe Control (FSC) and Safety Manager platforms. This assembly bridges the gap between field-mounted transmitters and the SAI-1620m safety analog input module. It organizes 16 dedicated channels into two isolated groups, providing essential signal conditioning and impedance matching to convert 0–25 mA field currents into 0–4 Vdc controller-level signals. We supply this unit as 100% Brand New and Original, ensuring mission-critical reliability for safety-instrumented systems (SIS).

Technical Specifications

The FC-TSAI-1620M utilizes precision components to maintain signal linearity and electrical protection across the safety loop.

Engineering Advantages

• High-Precision Signal Conversion: The module delivers 16-bit resolution with an accuracy of ±0.1%. This allows the Safety Manager to monitor process variables with extreme granularity, reducing the likelihood of nuisance trips in critical loops.

• Robust Fault Protection: Each channel features a 315 mAT slow-acting fuse and built-in short-circuit protection. These components isolate field-side wiring faults, preventing a single failure from compromising the entire I/O bank or the controller backplane.

• Flexible Transmitter Integration: The FC-TSAI-1620M supports both active and passive field transmitters. It provides current-limited output to field devices, simplifying the wiring architecture in complex industrial layouts.

• Environmental Resilience: Engineered for the harshest conditions, the module operates reliably from –40 °C to +70 °C. This makes it ideal for remote oil and gas installations or chemical refineries where internal cabinet temperatures fluctuate significantly.

FAQs

• Can the FC-TSAI-1620M handle standard 4-20 mA signals?

  Yes. While the module has a maximum input range of 0–25 mA, it is optimized for standard 4–20 mA process variables used in safety-instrumented functions.

• How does the module handle ground loops between channels?

  The 16 channels are split into two distinct groups of eight. Each group shares a common 0V reference, while the grouping helps isolate different field segments to minimize potential interference.

• What is the maintenance protocol for the channel fuses?

  The module uses standard 5 x 20 mm 315 mAT slow-acting fuses. Technicians can easily access and replace these fuses on the FTA without replacing the entire assembly, significantly reducing downtime during troubleshooting.

• Is this a genuine Honeywell FSC component?

  Absolutely. We guarantee that the FC-TSAI-1620M is 100% Brand New and original. Every unit undergoes rigorous factory testing and arrives in original Honeywell packaging with full technical documentation.
