Product Description


Honeywell FC-TSAI-1620M 16‑Channel Safety Analog Input Interface Module
Safety Analog Input Interface Module for Honeywell Safety Manager SIS, SIL3 Certified for Critical Sensor Signal Acquisition
1. Product Overview

The Honeywell FC-TSAI-1620M is a 16‑channel safety analog input interface module for Honeywell Safety Manager safety instrumented systems (SIS) and HC900 controllers. Certified to SIL3 (compliant with IEC 61508, IEC 61511, TÜV, UL, CSA, FM), it converts 4‑20 mA/0‑10 V analog signals from field sensors (temperature, pressure, flow transmitters) to digital signals for safety monitoring and control. The module features dual‑group channel isolation, 250 Ω precision input resistance, short‑circuit protection, and real‑time diagnostics, ensuring reliable operation in harsh industrial environments like oil & gas, chemical, and power generation.
