Honeywell FS-BSDOL-04UNI | Range Setting Module

Product Overview

The Honeywell FS-BSDOL-04UNI functions as a dedicated range-setting module for the SDOL-0424 loop-monitored output module within the Safety Manager SC system. This module sets precise current sensing thresholds across four independent output channels . Accordingly, the FS-BSDOL-04UNI prevents false lead-break detection on unused channels, ensuring reliable operation in safety-critical applications.

Technical Specifications

The FS-BSDOL-04UNI offers four load range settings labeled S, L, M, and H for flexible configuration . This module mounts directly on the programming connector of the I/O backplane without consuming additional chassis space . Furthermore, the module’s compact design simplifies installation while its modular construction permits customization through break-off sub-modules.

Key Design Features

The FS-BSDOL-04UNI features a main section (BSDOL-04) that mounts on the programming connector of the I/O backplane . Additionally, the module includes sixteen range-setting sub-modules (four each for S, L, M, and H types) placed into four designated positions on the main section . This modular design provides straightforward customization for specific current load requirements. Moreover, the module’s high ±0.5% resolution accuracy ensures reliable current sensing and loop-monitoring performance .

Application and Integration

The FS-BSDOL-04UNI integrates seamlessly with Honeywell Safety Manager SC and FSC systems, supporting both 24V DC and 48V DC field load configurations . System engineers deploy this module in emergency shutdown (ESD) and safety instrumented systems (SIS) for precise output monitoring . Consequently, it plays a critical role in maintaining safety integrity in oil and gas, chemical processing, and power generation facilities.
