Honeywell FC-RUSFDU-01 Fire and Gas Interface Module

Product Description

The FC-RUSFDU-01 is a high-performance Fire & Gas (F&G) detection interface module from Honeywell, designed to integrate field-mounted environmental sensors into industrial safety systems. This module ensures reliable acquisition of analog signals and provides immediate local control via onboard relays, making it ideal for safety-critical monitoring in hazardous industrial areas.

Engineered for remote and demanding environments, it features eight precision 4–20 mA input channels, four robust relay outputs, and Modbus RTU communication over RS-485, all in an IP65-rated enclosure.

Technical Specifications

Key Performance Features

• Reliable Signal Acquisition: Stable processing of 4–20 mA signals from toxic or combustible gas detectors and flame sensors.

• Direct Control Capability: Four onboard relays enable local actions (sirens, beacons, fans) independent of the main controller.

• Ruggedized Construction: IP65-rated for dust and low-pressure water protection, suitable for wash-down or outdoor areas.

• Flexible Communication: Modbus RTU settings allow integration with HMI, SCADA, or PLC systems for real-time safety monitoring.

Technical FAQ

What types of sensors can be connected?
Any standard 4–20 mA analog transmitter, including combustible gas (LEL), toxic gas (H₂S, CO, etc.), and optical flame detectors.

How does the module handle communication failures?
Relay outputs can be configured to maintain their last state or default to a safe state if RS-485 communication to the controller is lost, ensuring continued safety monitoring.
