FC-QPP-0002 Quad Processor Safety Controller Honeywell

Product Description

The FC-QPP-0002 is an advanced Quad Processor Pack (QPP) serving as the central logic engine for the Honeywell Safety Manager (SM) system. Engineered for Safety Instrumented Functions (SIF), this high-integrity controller employs a 2-out-of-4 (2oo4D) voting architecture to maximize diagnostic coverage and fault tolerance. It is a cornerstone for Emergency Shutdown (ESD), Fire & Gas (F&G) systems, and Burner Management Systems (BMS) in hazardous industrial environments.

The FC-QPP-0002 executes complex safety logic at high speed, managing all field I/O signals with precision. It supports dual-supply voltage operation (24 VDC and 5 VDC) and is housed in a robust 1.3 kg module. With a wide operating temperature range and global safety certifications—including TUV, FM, UL, CE, and CSA—this processor provides reliable protection for personnel, machinery, and process assets in refineries, petrochemical plants, and power generation facilities.

Technical Specifications

Key Reliability Features

• Fault Tolerance: Quad-Core architecture ensures safe operation even if one processor sub-component fails.

• Thermal Resilience: Rated up to 70°C, maintaining stable logic execution in dense cabinets.

• Robust Outputs: Short-circuit proof outputs with 1.1 kΩ series resistance protect against field-side wiring faults.

• Global Compliance: Certified for SIL 3 safety applications and use in hazardous industrial zones worldwide.

Technical FAQ

What is the primary difference between the FC-QPP-0001 and FC-QPP-0002?
The FC-QPP-0002 is a later revision with enhanced internal component efficiency, improved firmware compatibility for newer Safety Manager hardware, and the same 2oo4D safety architecture as the FC-QPP-0001.

Can this module handle high-current field devices directly?
No. The module provides logic-level outputs of 750 mA. High-current devices (e.g., deluge valves or large motors) require interposing relays or high-power digital output modules such as the FC-SDO series.
