Safety Manager Safe Analog Output | FC-TSAO-0220m Honeywell

Product Overview

The FC-TSAO-0220m (Model: FC-TSAO-0220m) is a high-integrity safe analog output module engineered for Honeywell Safety Manager®, FSC (Fail-Safe Controller), and Experion® PKS platforms. It is primarily utilized in Safety Instrumented Systems (SIS) to provide precise and reliable 0(4)–20 mA signals to critical field actuators, such as control valves and proportional positioning devices.

A key feature of the FC-TSAO-0220m (Part Number: FC-TSAO-0220m) is its integrated Field Termination Assembly (FTA) logic, which facilitates the interface between the system interconnection cable (SICC-0001/Lx) and external field wiring. The module supports HART communication on both channels, allowing for advanced device diagnostics and calibration. Furthermore, it allows for serial connection of up to eight modules to fully utilize the 16 channels of a HART multiplexer, ensuring comprehensive asset management in oil, gas, and power generation facilities.
