Description
Product Overview
The Honeywell 10005/1/1 Watchdog Module is a critical safety component within the FSC system, designed to monitor processor integrity, voltage stability, and memory health. It ensures that the application loop executes correctly—neither hanging nor skipping—and provides independent fault detection via a galvanically isolated 24 VDC ESD input.
