Honeywell FC-TSRO-0824 Digital Output Field Termination Assembly
The FC-TSRO-0824 is a Digital Output Field Termination Assembly (FTA) manufactured by Honeywell, designed for use in the company’s Safety Manager and Experion® PKS process automation and safety systems. It serves as a critical interface between the control system’s interconnection cables and field-mounted devices, providing 8 channels of isolated, relay-based, potential-free digital output for safety and control applications.
This module is purpose-built for SIL3 safety applications (per IEC 61508), ensuring high-integrity, fail-safe operation in demanding environments. It features robust relay outputs with electrical isolation, screw-terminal field wiring, and a rugged industrial design to support reliable switching of field devices.
