USI-0002 | FC-USI-0002 | Honeywell Safety Manager Module

Honeywell FC-USI-0002 Universal Safety Interface SM Module

Product Description

The FC-USI-0002 (USI-0002) is a high-performance Universal Safety Interface module designed for the Honeywell Safety Manager and Fail-Safe Controller (FSC) systems. This multi-functional interface serves as a versatile bridge between field instrumentation and the safety processor, supporting a broad spectrum of signal types including analog (4-20 mA), digital I/O, and temperature sensors (RTD/Thermocouple). By centralizing these diverse inputs into a single hardware profile, the FC-USI-0002 (USI-0002) simplifies cabinet architecture and reduces spare part inventory requirements.

Engineered for SIL 2 and SIL 3 environments, the FC-USI-0002 (USI-0002) features native HART protocol pass-through, allowing for remote calibration and diagnostics of smart field devices without interrupting safety logic. The module utilizes an FDX backplane communication protocol to maintain deterministic data exchange with the central controller. Its robust electrical isolation (up to 2500 V AC) and redundant 5 Vdc supply paths ensure that signal processing remains uncompromised even during localized electrical faults or power supply fluctuations.
