Technical Summary

10005/1/1 is identified as a Honeywell Fail Safe Controller watchdog module supplied with the 10005/O/3 subassembly. It belongs to the FSC node hardware group used in legacy safety-system installations.

The unit should be treated as a system-specific supervisory component. Replacement planning must preserve the original FSC node design, card-file arrangement and installed revision.

Specifications

Features

• Dedicated watchdog role within an FSC node
• Configured hardware assembly rather than a general-purpose I/O module
• Designed for installed-base safety-system maintenance
• Supports controlled spare-part and migration planning

Compatibility

Use only in a compatible Honeywell FSC node after checking the installed card file, system bus, adjacent modules and maintenance records. The 10005/1/1 should not be substituted with a diagnostic and battery module or a processor module.

Replacement

Honeywell placed TPN coaxial parts, including this FSC watchdog module, on a phase-out path with End of Sale scheduled for December 31, 2025. Sites retaining FSC hardware should coordinate spares, repair strategy and modernization planning with the plant safety lifecycle.
