Honeywell FC-PDB-0824P Power Distribution Board

Product Description:

The Honeywell FC-PDB-0824P is an 8-channel, 24 VDC Power Distribution Board (PDB) designed for the Honeywell Safety Manager (SM) System, providing reliable power distribution to Field Termination Assemblies (FTAs) and I/O modules within industrial safety and control environments. The board accepts a nominal 24 VDC input (with a tolerance of –15% to +30%) and distributes regulated power across eight independent output channels, each individually fused with a 2 AT slow-acting fuse (5 × 20 mm) to protect downstream devices from overcurrent conditions.
The FC-PDB-0824P features a compact, modular design with physical dimensions of 94 × 109 × 71 mm (3.7 × 4.3 × 2.8 in), weighing approximately 0.93 kg, and mounts securely on standard DIN EN rails (TS32 / TS35 × 7.5) with a used rail length of 95 mm. Its robust construction supports an operating temperature range of –40 °C to +70 °C (–40 °F to +158 °F), making it suitable for harsh industrial environments. The board utilizes Weidmuller connectors: a BVZ 7.62/02F SW 2-pole keyed header for the main 24 VDC input, and BL 5.08/2 SN OR 2-pole socket blocks for each of the eight field output connectors, ensuring secure and polarity-correct connections.

Frequently Asked Questions (FAQ):

What is the maximum current rating per output channel on the FC-PDB-0824P?
Each of the eight output channels on the FC-PDB-0824P is protected by an individual 2 AT (slow-acting) fuse, with a maximum current rating of 2 A per channel.

What type of fuses should be used for replacement on the FC-PDB-0824P?
The FC-PDB-0824P requires 5 × 20 mm slow-acting fuses with a maximum rating of 2 AT. Always use manufacturer-specified fuse ratings to maintain safety certifications and channel protection. includes a configurable ESD function via Channel 32 for dedicated safety-related applications. This function can be enabled or disabled using the ESD (CH32) link on the IOTA (I/O Termination Assembly). The ESD function provides a hardwired safety shutdown capability independent of the software logic, ensuring reliable emergency response. has six jumpers that can be used to apply or remove power from a relay when used with a TDBS board. 

What are the input voltage requirements for the FC-PDB-0824P?
 The FC-PDB-0824P operates on a nominal 24 VDC input with a tolerance range of –15% to +30%, and connects to the main power bus via a Weidmuller BVZ 7.62/02F SW 2-pole keyed header.

Application:

Power Generation: Providing isolated power distribution within thermal, nuclear, or hydroelectric control rooms to prevent electrical noise from causing false trips on heavy turbines.
Oil and Gas (Upstream & Downstream): Used on offshore drilling platforms, subsea control ties, pipelines, and refinery cracking units where explosion-proof (ATEX) components are legally mandatory.
Chemical and Petrochemical Plants: Managing control cabinet power for volatile chemical processing loops where precise interlocking safety logic protects human life and assets.
Pharmaceutical and Water Treatment: Powering critical dosing and process isolation networks where a power drop could compromise batch purity or environmental compliance.
