Product Description

High-Integrity Interface for HART-Enabled Safety Systems

The Honeywell FC-TSHART-1620M is a high-performance Analog Input Field Termination Assembly (FTA) specifically engineered for the Honeywell Fail-Safe Control (FSC) and Safety Manager architectures. This assembly acts as the critical physical interface between 16 channels of field-mounted smart transmitters and the safety system’s controller. By supporting the HART (Highway Addressable Remote Transducer) protocol, the FC-TSHART-1620M enables the acquisition of precise 4–20 mA analog process variables while simultaneously facilitating secondary digital data exchange for advanced diagnostics, predictive maintenance, and remote instrument configuration.

Engineered for SIL 3 Safety Environments

Designed to meet the rigorous demands of Safety Instrumented Systems (SIS), the FC-TSHART-1620M ensures high signal integrity with 16-bit resolution and a typical accuracy of ±0.1%. The assembly provides robust isolation and is rated for a maximum supply voltage of 30V DC, ensuring protection against field-side electrical surges. Its ability to monitor the status of HART-enabled devices allows for the detection of "hidden" faults within transmitters, significantly increasing the Safe Failure Fraction (SFF) of the entire safety loop. This makes the FC-TSHART-1620M an essential component for critical operations in oil and gas, refining, and power generation where SIL 3 compliance is a mandatory requirement.
