Honeywell FC-QPP-0001

Product Name: Quad Processor Pack (Safety Manager)

Product Introduction: The FC-QPP-0001 is the core central processing unit for Honeywell Safety Manager systems, executing SIL3 certified safety logic using quad-redundant or dual-lockstep architectures.

Category: Honeywell

Description

Technical Specifications:

Processor: 4x PowerPC cores (QMR – Quad Modular Redundant) or Dual processors with dual memory sets
Architecture: 2oo4D (Two-out-of-Four with Diagnostics)
Safety Grade: SIL 3 (IEC 61508)
Memory: 1 GB DDR2 SDRAM per set / 256 MB Flash
Communication: Ethernet 10/100 Mbps, Modbus, Profibus

Functional Features: Executes Functional Logic Diagrams (FLDs); manages Universal Safety I/O (USIO); performs continuous self-diagnostics (>99% coverage); voting logic comparison.

Performance Parameters:
Operating Temp: -40°C to +70°C (Cabinet), -5°C to +70°C (Remote)
MTBF: >100,000 hours
Power: 24 VDC (from rack)
Dimensions: 88 × 227 × 175 mm (approx 3U/6U VME style)

Material Composition: Rigid metal faceplate; multi-layer PCB with gold contacts; heat spreader; conformal coating (CC variants).

Structural Characteristics: Front panel LCD/status display; keyed module edges; VME-based 6U form factor; redundant high-speed sync link connectors on backplane.

Working Principle: Four (or dual paired) processors execute identical safety code in parallel; hardware comparators verify results cycle-by-cycle; 2oo4D voting discards erroneous outputs and forces safe state on divergence.

Advantages Highlights: Eliminates single point of failure; TUV certified SIL3; online module replacement in redundant pairs; high-speed cause-effect processing.

Applicable Industries: Offshore Oil & Gas, Refineries, Chemical Plants, Power Boiler Management, Pipeline Stations.

Model Series: Honeywell Safety Manager Gen 2 / FSC QPP Modules.

Installation Requirements: Install in primary/secondary QPP slots of Safety Manager chassis; connect synchronization cable if redundant; ensure 24 VDC backplane power is present.

Usage Precautions: Must be used in pairs for full redundancy; do not mix different hardware revisions in redundant setup; ensure logic is compiled for QPP architecture; monitor diagnostic LEDs for comparator mismatch.
