Product Introduction
The Honeywell FS-TSDI-16115 is a Safe Digital Input FTA (Field Terminal Assembly) Module, specifically designed for Honeywell’s Safety Manager™ platform. This module plays a pivotal role in safety instrumented systems (SIS) by safely acquiring digital input signals from field devices such as limit switches, emergency shutdown devices, and other binary sensors. It is an integral component in mission-critical applications where SIL (Safety Integrity Level) certifications are required.
The FS-TSDI-16115 module ensures reliable transmission of signals while maintaining galvanic isolation between field and control systems. This enables seamless and safe operation within harsh industrial environments such as petrochemical plants, power generation facilities, and offshore platforms.
