1. Product Overview
Brand / Series / Positioning
-
Brand: Honeywell
-
Series: Safety / Field Termination Assembly (FTA) / Safe Analog Input Modules
-
Positioning: The FC‑TSHART‑1620M is a safe analog input field termination assembly module with HART interface support. It is designed to serve as an interface between field analog sensors / transmitters (0/4–20 mA) and the safety logic / analog input modules (e.g. a safe high‑density analog input module). This FTA module not only provides signal conversion and conditioning, but also supports HART multiplexing capability, power distribution, and diagnostic monitoring suited for hazardous locations (e.g. Class I Division 2) setups.
It typically sits in the link between field sensors and safety controllers, allowing the system to read analog measurements (pressure, temperature, flow, level) in a safe, monitored, and HART‑capable way.

3. Product Description & Features
The FC‑TSHART‑1620M operates as a safe analog input FTA with added HART compatibility. Its duties include:
-
Analog signal conversion: Converts 0(4)–20 mA field sensor signals into voltage signals (0–4 V) for the safe analog input module domain, preserving accuracy.
-
HART multiplex interface: It is capable of interfacing with HART multiplexers (e.g. those from MTL, Pepperl+Fuchs) to allow communication with field transmitters over the same loop.
-
Power distribution: It distributes power to each transmitter loop with current and voltage limitation, ensuring safe operation in hazardous areas.
-
Diagnostic monitoring: It monitors external supply, transmitter current draw, fault detection, and likely wiring failures.
-
Field termination convenience: Screw terminal design, DIN rail snap mounting, organized layout for wiring and field loops.
-
Hazardous area suitability: Designed to operate in environments with Class I Division 2, ensuring safe performance even in zones with explosive atmosphere risk.
In application, sensors (pressure, temperature, flow, level) send analog current signals; the TSHART FTA conditions these signals, injects loop power, reads diagnostics, and conveys a safe, clean voltage to the safety logic modules — all while enabling HART communication in parallel.
