Honeywell FC-PDB-ARTF05 Safety Manager A.R.T. Power Distribution Board

HONEYWELL FC-PDB-ARTF05 Safety Manager A.R.T. Power Distribution Board (5VDC/16A In, 5VDC/4A Out)

The Honeywell FC-PDB-ARTF05 is a fused Power Distribution Board (PDB) engineered specifically for the Honeywell Safety Manager (SM) architecture and Fail Safe Control (FSC) platforms. Operating within Advanced Redundant Technology (A.R.T.) environments, this unit delivers isolated, deterministically protected 5 VDC distribution across mission-critical input/output sub-racks, controller backplanes, and safety instrumentation loops.

This design contains local short-circuits to the affected loop, eliminating risk to upstream switch-mode power supplies (SMPS) or adjacent safety channels. Whether deployed in harsh marine switchgear rooms, offshore floating production storage and offloading (FPSO) emergency shutdown systems (ESD), or refinery burner management systems (BMS), the FC-PDB-ARTF05 provides consistent rail voltage stability, low ripple transmission, and rapid channel fault diagnosis.

Technical Details

Key Features

1. Redundant High-Capacity Bus Inputs: Features dual 5 VDC input feeds (5V-1 and 5V-2) rated up to 16 A per channel, fully supporting redundant power topologies without bus contention.
2. Dedicated Channel Overcurrent Protection: Equipped with standardized 4 A automotive blade fuses (Littelfuse 0287004.PXS series rated to 32 VDC) on each distribution branch to suppress localized fault current propagation.
3. Dual DIN-Rail Mounting Footprint: Pre-fitted with universal mounting shoes compatible with both asymmetrical TS32 and standard symmetrical TS35 x 7.5/15 DIN rails for secure mounting inside marine consoles.
4. Integrated Pin-Header Interconnects: Utilizes heavy-gauge multi-position action pin headers for power trunk lines and dedicated 3-pole monitoring/distribution headers for sub-rack interconnect wiring.
5. High-Vibration Marine Grade PCB: Multi-layer board finished with moisture-resistant conformal coating, mitigating contact fretting and short circuits in high-humidity, marine-engine-room environments.

Frequently Asked Questions

What is the primary function of the Honeywell FC-PDB-ARTF05?

The FC-PDB-ARTF05 distributes regulated 5 VDC power to input/output sub-racks and logic modules within Honeywell Safety Manager and Fail Safe Control (FSC) systems. It provides overcurrent protection on each output branch via blade-type fuses, preventing single field-wiring shorts from downing an entire safety system.

Can the input channels handle more than 16 A if tied in parallel?

No. The board’s physical traces and 4-position action pin headers are rated for a strict maximum of 16 A per input line (5V-1 and 5V-2). Tying inputs together to source greater than 16 A will exceed thermal limits and can cause permanent damage to the PCB substrate.

What exact fuse type does this board take, and what is its continuous load limit?

The board uses Littelfuse 0287004.PXS 4 A / 32 VDC fast-acting blade fuses (standard 5 x 19 mm form factor). While rated at 4 A nominal, the continuous sustained output current limit per fuse branch is 2.8 A to maintain thermal equilibrium and avoid nuisance trips.

Is the FC-PDB-ARTF05 backward compatible with older Honeywell FSC systems?

Yes. The FC-PDB-ARTF05 is compatible with earlier FSC systems (often cataloged under the FS- prefix) and Safety Manager R100/R200 systems utilizing standard A.R.T. mounting sub-racks.

Which DIN rail profiles can this board be mounted on?

The module’s integrated mounting hardware mounts directly to either asymmetrical G-profile DIN rails (TS32) or standard symmetrical top-hat DIN rails (TS35 x 7.5 mm or TS35 x 15 mm). It requires 235 mm of clear rail width.
