Product Overview

The Honeywell 10002/1/2 serves as the core Central Processor Unit (CPU) within the Fail-Safe Control (FSC) system. It acts as the "brain" of the safety system, executing complex logic solvers and ensuring that all I/O modules are synchronized across the system's backplane. Designed for mission-critical industrial applications, this module ensures safety-instrumented functions (SIF) are executed with deterministic timing, which is essential for systems like Emergency Shutdown (ESD) and Fire and Gas (F&G). We supply this unit as 100% brand new, original factory stock to guarantee the reliability required for certified safety operations.

Technical Specifications

Engineering Advantages

• High-Integrity Logic Execution:
  The 10002/1/2 ensures fixed scan times, which guarantees that critical safety logic cycles are executed at predictable intervals, making it ideal for SIL-certified performance.

• Deterministic Fault Management:
  Integrated watchdog timers and self-diagnostic routines allow the CPU to detect internal faults (hardware or memory) instantly, transitioning the system into a safe state before any process hazard occurs.

• Stable Power Consumption:
  The module operates on a 5 VDC bus with high noise immunity, maintaining stable processing in electrically noisy environments (e.g., near high-voltage switchgear), ensuring reliable operation in industrial conditions.

• Scalable Memory Architecture:
  With expandable application memory (up to 1 Mbyte), the 10002/1/2 CPU can handle extensive safety logic, including complex cause-and-effect matrices and large-scale I/O mapping for large plant safety systems.

FAQs

• What is the difference between the 10002/1/2 and older CPU revisions?
  The /1/2 revision introduces hardware enhancements and larger memory capacities compared to earlier versions, supporting mid-to-late generation FSC racks. Ensure compatibility with your Honeywell Safety Builder project and firmware.

• Does this module support redundant (DMR) configurations?
  Yes, the 10002/1/2 is often used in redundant configurations (typically in pairs) within a redundant processor chassis to ensure high availability. If the primary CPU fails, the standby unit takes over without interrupting safety functions.

• How is the safety application loaded onto the module?
  The application logic is compiled using Honeywell Safety Builder software and then downloaded to the module’s non-volatile EPROM/RAM, where it is executed deterministically by the CPU.

• What are the status indicators on the front panel?
  The module has LED indicators that show the CPU’s operational mode (e.g., Run, Stop, Fault), providing quick visual feedback to maintenance personnel for a fast health check of the safety controller.
