Honeywell FC-TSAOH-0220m Safe Analog Output FTA Module

The Honeywell FC-TSAOH-0220m is a high-reliability Safe Analog Output Field Terminal Assembly (FTA) Module specifically designed for use within Honeywell’s Safety Manager and Fail-Safe Control (FSC) systems. It is typically employed in safety-critical applications where analog output signals—such as those controlling valves, actuators, or indicators—require secure and reliable transmission under stringent industrial and safety standards.

This module serves as an interface between the control system and field devices, ensuring isolated, filtered, and safe analog signal outputs. It supports multiple channel configurations and adheres to SIL3 requirements in accordance with IEC 61508, making it ideal for use in process industries such as oil and gas, petrochemicals, and power generation.
