Honeywell FC-QPP-0002 CC v1.2 Quad Processor Pack

The Honeywell FC-QPP-0002 CC v1.2, also cataloged as the FC-QPP-0002 Quad Processor, operates as a dedicated hardware component for high-integrity safety logic processing and execution within Honeywell Safety Manager and Fail Safe Control systems.

Hardware Specifications

Channel-to-Channel Isolation & Cold Junction Compensation

The main processing board provides physical galvanically isolated channels and internal power decoupling barriers to protect processing logic from voltage swings on field side lines. Signal routing paths filter line noise before field inputs reach internal bus registers, preventing common-mode noise propagation from disturbing connected 4-20 mA HART loop protocol interfaces. Isolated logic interfaces minimize ambient noise coupling across high-density I/O subsystems and preserve high measurement fidelity across cold junction compensation (CJC) circuits within connected safety input modules.

Frequently Asked Questions

Q: What are the backplane power supply voltage limits for the FC-QPP-0002 CC v1.2?

A: The module requires a regulated 5 Vdc supply (+/- 5%) with a maximum current consumption of 1.2 A, alongside a 24 Vdc auxiliary line tolerance (-15% to +30%) pulling up to 25 mA.

Q: What short-circuit protections are built into the module output channels?

A: Output paths feature continuous short-circuit protection and reverse-polarity safeguards, with driving capability up to 750 mA per channel.

Q: What ambient temperature range is rated for module operation?

A: Both internal module and external ambient envelope ratings support operating temperatures ranging from -5 to +70 deg C (10 to 95% non-condensing relative humidity).

Field Installation Guidelines

1. Slide the processor pack squarely along chassis guide rails into its designated slot on the system backplane rack until rear connectors engage fully.
2. Secure front retention screws to lock the assembly against backplane vibrations and ensure frame grounding continuity.
3. Verify that 5 Vdc and 24 Vdc auxiliary rack power rails comply with tolerance limits prior to powering the rack enclosure.
4. Connect all field communication and I/O trunk cables using shielded twisted pair conductors terminated directly at the central earthing bar.
5. Maintain clear convection air channels above and below the card cage module to prevent localized heat accumulation inside sealed cabinets.
