Honeywell FC-PDB-0824P V1.0 Power Distribution Board

Configured for 24 VDC power distribution in Honeywell Experion PKS platforms, the Honeywell FC-PDB-0824P V1.0 (FC-PDB-0824P Power Distribution Board) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

Designed for DCS cabinet power management, the module splits primary 24 VDC input power into 8 individually fused output channels rated at 2 A per branch. Built-in channel-to-channel isolation restricts fault currents to local outputs, preventing field-side overload conditions on fan units or Field Termination Assemblies (FTAs) from compromising main system power rails. This structural isolation safeguards signal integrity across connected 4-20 mA HART loop instruments and digital control interfaces.

Frequently Asked Questions

Q: What indicates an overcurrent or blown fuse fault on an individual output channel?

A: Each output branch features an onboard diagnostic LED indicator; an extinguished channel LED signals a blown 2 A channel fuse or open-circuit fault condition on that specific output circuit (Out1-Out8).

Q: What connectors are required for field wiring connections on the input and output terminals?

A: Main 24 VDC input power requires a Weidmuller BVZ 7.62/02F SW terminal connector, while the 8 individual output branches utilize pluggable Weidmuller BL 5.08/2 SN OR or equivalent compatible block connectors.

Field Installation Guidelines

• De-energize primary 24 VDC supply circuits before making or breaking connections on the input and output terminal blocks.
• Mount the board securely on a standard DIN rail, preserving recommended vertical spacing to facilitate convection cooling in high-density panels.
• Strip power cables to standard conductor engagement lengths and land incoming 24 VDC main lines into the Weidmuller BVZ 7.62 input connector with verified polarity.
• Interconnect output loads using Honeywell PDC-MB24-x series cable assemblies or equivalent wire gauges sized for 2 A continuous load per channel.
• Tighten all terminal screws to connector manufacturer torque specifications to prevent loose contact points and thermal rise
