10020/1/2 | Honeywell Quad Processor Module (QPM)

The Honeywell 10020/1/2 Quad Processor Module (QPM) is a key component of the FSC Version 80x.x Fail-Safe Controller System. It supports safety-critical operations and ensures high availability through Quadruple Modular Redundant (QMR) architecture, adhering to Safety Integrity Level (SIL) 1–3 standards as per IEC 61508 and EN 61511.

System Overview

The FSC Version 80x.x integrates advanced safety and process control functions for various applications, including:

High-integrity process control.
Emergency shutdown and process safeguarding.
Turbine and compressor protection.
Burner/boiler management.
Fire and gas detection.
Pipeline monitoring.

Architectures Supported

The system accommodates multiple configurations based on safety and operational needs:

DMR (Dual Modular Redundant): 1oo2 voting.
QMR (Quadruple Modular Redundant): 2oo4D voting.

Certified System Configuration

The QPM operates in configurations with single or redundant CPUs and I/O systems, supporting varying levels of redundancy and fault tolerance.

Key Features of the 10020/1/2 QPM

Fault Tolerance:
- Supports continuous operation by isolating faulty central parts in redundant configurations.
- System maintains safety during internal or external faults.
Safety Operations:
- Digital inputs default to “0 signal” and analog inputs use configured minimum limits during module faults.
- Redundant systems overwrite faulty signals with corrected inputs from the other central part.
Output Module Failures:
- Localized faults trigger group shutdown for the affected channel, with defined operation periods based on Probability of Failure on Demand (PFD) calculations.
Operational Integrity:
- Certified for safety-related applications up to SIL 3.
- Approved by TÜV SÜD for recertification against international safety standards.
