The Honeywell FC-SAI-1620M is a high-density, safe analog input module designed for integration within the Honeywell Safety Manager system. This module is engineered to handle critical process variables, providing 16 channels of 0(4)–20 mA analog signal processing. Built for functional safety applications, the FC-SAI-1620M ensures that field transmitter data is accurately digitized and communicated to the safety processor, supporting Safety Integrity Level (SIL) requirements in demanding industrial environments.
The FC-SAI-1620M features advanced internal diagnostics that continuously monitor the health of each input channel. By providing galvanic isolation between the field sensors and the system backplane, the module protects the central safety logic from electrical transients and ground loops. Its robust design is capable of operating in extreme temperature ranges from -40°C to +70°C, making it ideal for the decentralized cabinets often found in oil and gas refineries, petrochemical plants, and power generation facilities. When utilized in a redundant configuration, this module provides the fault tolerance necessary for mission-critical monitoring where unplanned downtime is not an option.
Emergency Shutdown (ESD): Monitoring pressure and flow transmitters for high-integrity safety trip logic.
Fire and Gas Systems: Processing analog signals from flame and combustible gas detectors.
Critical Process Control: Maintaining redundant monitoring of boiler levels or reactor temperatures in power and chemical plants.
Hazardous Area Monitoring: Safe signal acquisition from Class I, Div 2 locations via appropriate field termination assemblies (FTAs).
