        Overview Manuals Specifications Monitoring & Control Application Scenarios System Integration

        Features:

        • Two-out-of-three voting architecture for dependable watchdog supervision.
        • Independent emergency shutdown inputs for direct de-energization.
        • Combined monitoring of program timing, supply voltage, and memory faults.
        Honeywell 10005/1/1 uses three watchdog sections and two-out-of-three voting to reduce dependence on a single monitoring path. This architecture supports dependable supervision of critical FSC controller operation and permits watchdog testing within the intended system design.

        Honeywell 10005/1/1 provides hardware-based shutdown paths that do not depend solely on successful application-program execution. Its emergency shutdown inputs can remove the watchdog output when an external safety condition requires the connected system to enter its defined safe response.

        Honeywell 10005/1/1 combines application-loop timing, internal supply-voltage supervision, and CPU, COM, and MEM error indications in the watchdog decision. These functions help detect abnormal controller execution before unsupervised operation can continue.

        The 10005/1/1 Honeywell Watchdog Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Emergency Shutdown: Supports watchdog supervision within FSC emergency shutdown configurations.
        • Burner Management: Provides controller-execution supervision in FSC-based burner and boiler management systems.
        • Equipment Safeguarding: Supports FSC installations used for turbine and compressor safeguarding.
        • Fire and Gas: Provides watchdog supervision within FSC fire-and-gas detection system configurations.
        • FSC Installation: Designed for installation in the Honeywell Fail Safe Controller central-part configuration.
        • Input Integration: Accepts the specified ESD1, ESD2, and reset signals used by the FSC watchdog circuit.
        • Output Loading: Supplies the 5 V DC WDGOUT signal to compatible FSC output modules within the stated current limit.
        • Load Expansion: Uses a compatible watchdog repeater when connected modules require more current than the watchdog output can supply.
        Description
        Honeywell 10005/1/1 supervises the maximum and minimum execution times of the FSC application loop. Maximum-time supervision detects a program that has stopped progressing or entered a continuous loop, while minimum-time supervision helps identify skipped program sections. Together, these checks confirm that the application executes within its expected cycle window.

        Honeywell 10005/1/1 monitors the internal 5 V DC supply for overvoltage and undervoltage conditions outside the permitted ±5% range. It also receives memory-error indications from FSC CPU, COM, and MEM modules. An applicable memory or supervision fault causes the watchdog output to de-energize so that connected circuits can follow the configured system response.

        Honeywell 10005/1/1 includes a galvanically isolated ESD1 input that can de-energize the watchdog output independently of normal processor execution. Separate ESD2 and reset inputs support the FSC watchdog arrangement, while the internal two-out-of-three voting design prevents the decision from depending on only one watchdog section.

        Honeywell 10005/1/1 operates from the FSC 5 V DC supply and provides a protected WDGOUT connection for compatible FSC output modules. System designers must keep the connected load within the specified output-current limit and use an approved watchdog repeater when additional load capacity is required.

        Technical notes
        Honeywell 10005/1/1 is an FSC watchdog module that supervises application-loop timing, the internal 5 V DC supply, and module error indications. Its WDGOUT connection is a protected 5 V DC watchdog output; the 24 V DC ratings apply to the ESD1 and reset inputs, not to relay trip outputs.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Is Honeywell 10005/1/1 still available directly from the OEM?
        No. Honeywell has discontinued the FSC platform and replaced it with Safety Manager. Buyers should treat Honeywell 10005/1/1 as a legacy spare and verify condition, revision, testing, warranty, and return terms with the supplier before purchase.
        What should an engineer check before installing Honeywell 10005/1/1?
        Confirm the exact part number, FSC hardware configuration, slot assignment, supply condition, connected WDGOUT load, and required output adapter or repeater. Installation should follow the site’s approved FSC maintenance procedure and safety-management controls.
        Why might Honeywell 10005/1/1 de-energize WDGOUT after replacement?
        Possible causes include an invalid application-loop timing condition, a 5 V DC supply outside tolerance, an active CPU, COM, or MEM error indication, an asserted ESD input, or an excessive WDGOUT load. Diagnose the FSC system before replacing the module again.
        Should a purchaser replace Honeywell 10005/1/1 or migrate the complete system?
        A replacement module may restore an installed FSC system temporarily, but Honeywell identifies FSC as discontinued and recommends migration to supported safety platforms. The decision should consider spare availability, certification obligations, lifecycle risk, planned downtime, and migration scope.
