The Honeywell FC-QPP-0002 is a high-performance Quad Processor Pack (QPP) designed as the central processing core for the Honeywell Safety Manager system. This module is engineered to provide the computational power and fault tolerance required for mission-critical functional safety applications. By utilizing a unique Quad Module Redundancy (QMR) architecture, the FC-QPP-0002 executes complex safety logic, manages system I/O synchronization, and ensures that process demands are met with absolute reliability. It is an essential component for plants migrating to or maintaining Safety Integrity Level (SIL) 3 environments.
The FC-QPP-0002 operates by running four identical processing paths in parallel, continuously comparing data to detect and isolate hardware faults without interrupting the control process. This robust design allows for "2-out-of-4" voting logic, providing an unparalleled balance between safety and system availability. The module is built to withstand harsh industrial conditions, featuring a wide operating temperature range and comprehensive galvanic isolation. It handles both 24 Vdc and 5 Vdc supply rails internally to maintain stable logic execution and communication with the Safety Manager backplane. Its precision engineering ensures seamless integration with Experion PKS and older TPS systems, offering a reliable upgrade path for aging QPP-0001 installations.
