Module Overview
The Honeywell 10020/1/2 Quad Processor Module (QPM) is an advanced CPU module designed for the Fail-Safe Controller (FSC) Version 80x.x system. It ensures uninterrupted operation in safety-critical environments through a Quadruple Modular Redundant (QMR) architecture. Moreover, it meets international standards IEC 61508 and EN 61511, supporting Safety Integrity Level (SIL) 1–3 applications.
The QPM guarantees system integrity even under internal or external faults by isolating defective parts while maintaining safe operation. It supports both DMR (1oo2) and QMR (2oo4D) configurations, making it ideal for high-integrity process control and emergency protection systems.
Functional Highlights
- Quad Redundancy Architecture: Operates with four processors for high reliability and fault tolerance.
- Safety-Certified Design: Approved by TÜV SÜD for SIL 1–3 safety-critical applications.
- Intelligent Fault Handling: Automatically isolates faulty inputs and substitutes valid data from the redundant CPU.
- Versatile Operation: Works with single or redundant central parts, ensuring continuous process control.
- Fail-Safe Input Handling: Digital inputs default to “0 signal,” and analog inputs switch to configured minimum limits during failures.
- Secure Output Management: Localized output module faults trigger controlled shutdowns within defined PFD-based periods.
