Product Introduction
The Honeywell FC-TDIO01 is a Security Manager SC Hardware module designed as part of the Honeywell Safety Manager (SM) system within the Experion Process Knowledge System (PKS) architecture. This module is primarily responsible for Total Distributed Input/Output (TDIO) functions, integrating both digital and analog I/O into a centralized, fault-tolerant safety system. It is specifically engineered to support Safety Instrumented Systems (SIS) and critical process control in highly regulated industrial environments such as oil & gas, refining, power generation, and chemical plants.
The FC-TDIO01 serves as a bridge between field devices and the control processor, handling signals for input sensors and output actuators while ensuring fail-safe operation, real-time diagnostics, and deterministic behavior. As part of Honeywell’s Safety Manager SC family, it supports high availability configurations and adheres to IEC 61508 and ISA S84 standards for SIL 3 applications.
