FX-USI-0002 Universal Serial Interface Module

Key Features and Advantages

The Honeywell FX-USI-0002 universal serial interface module provides critical connectivity between Honeywell control systems and legacy serial devices. Engineered for industrial environments, it features dual independent serial channels supporting RS-232, RS-422, and RS-485 protocols at data rates up to 115.2 kbps. The module’s 1500V RMS isolation protects sensitive control equipment from electrical noise and ground loops common in industrial settings.

Configuration flexibility: Each channel on the FX-USI-0002 can be independently configured for different protocols and baud rates, enabling simultaneous communication with diverse equipment such as barcode scanners, weigh scales, and legacy PLCs. The module automatically detects signal types and handles protocol conversion without additional hardware, simplifying system integration.

Robust industrial design: Operating reliably across a wide temperature range (-20°C to +70°C), the FX-USI-0002 withstands harsh plant conditions. Its ATEX Zone 2 certification ensures safe operation in potentially explosive atmospheres. LED indicators provide instant visual status of power and communication activity for each channel, facilitating quick diagnostics.

Seamless integration: The module connects directly to Honeywell ControlBus backplanes, appearing as a native resource in control system configurations. Engineers can access serial devices using standard function blocks without low-level programming. The FX-USI-0002 supports transparent mode for simple device integration and protocol-specific modes for optimized communication with common industrial equipment.

Diagnostics and maintenance: Comprehensive status reporting through the control system enables remote monitoring of communication health. The module’s hot-swappable design allows replacement without system shutdown in redundant configurations. With low power consumption (3.5W typical), the FX-USI-0002 minimizes heat generation in control cabinets while maintaining reliable serial connectivity for critical automation systems.
