Product Introduction
The Honeywell FC-TSDI-16115 is a Safe Digital Input Field Terminal Assembly (FTA) module designed for Honeywell’s Safety Manager (SM) and Fail-Safe Controller (FSC) platforms. This module supports both active and passive digital input types, allowing integration of a wide range of field signals such as contact closures, proximity switches, or electronic signal transmitters.
Built to meet SIL3 safety standards under IEC 61508, the FC-TSDI-16115 ensures safe acquisition of input signals in critical industrial control systems such as emergency shutdown (ESD), fire & gas, and burner management systems. Its modular design enables flexibility, reliability, and ease of integration in safety instrumented systems (SIS).
