- Compatibility review covers documented fan assembly, receiving hardware and configuration.
51303940-250 is the documented Honeywell cabinet fan assembly for TDC 2000 and TDC 3000. As the installed cooling assembly, it maintains forced airflow through installed control hardware through DCS cabinet airflow. Its execution is defined by documented fan assembly, so signal direction, receiving hardware and configured channel use must agree with the approved system design.
Before replacement, record the installed position, terminal or backplane assignments, connected devices and current configuration status. Match the complete catalog marking, cooling assembly, DCS cabinet airflow, documented fan assembly, receiving assembly and every printed revision. After installation, restore the approved configuration, check module and system diagnostics, and prove every affected measurement, command or communication path before return to service.
The 51303940-250 Honeywell Cabinet Fan Assembly may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
