Foxboro P0926HZ I/A Series Redundant FBM Baseplate

Product Description

Overview of the P0926HZ Baseplate

The Foxboro P0926HZ is a redundant baseplate assembly developed for the Foxboro I/A Series and Evo™ distributed control systems. It serves as the physical and electrical mounting platform for compatible Fieldbus Modules (FBMs), enabling secure installation, power distribution, and system communication.

Designed for high-availability architectures, the P0926HZ allows redundant FBM pairs to operate simultaneously, ensuring continuous process monitoring even during module faults.

Role Within the Control System

This baseplate functions as the interface between FBM I/O modules and the system backplane. It routes power, communication signals, and timing references while maintaining electrical isolation. By supporting redundant configurations, it plays a critical role in fault-tolerant control strategies commonly used in safety-critical plants.

The design supports deterministic data exchange and reliable signal integrity across the control network.

Supported Modules and Applications

The P0926HZ is compatible with selected Foxboro analog input FBMs, including FBM217, FBM218, and FBM219, when deployed in redundant pairs. Typical applications include:

Oil and gas production facilities
Petrochemical and chemical processing units
Power generation plants
Large-scale continuous process operations

In these environments, maintaining uptime and communication stability is essential.
