Foxboro P0926HT I/A Series 8-Position Modular Baseplate

Description

The Foxboro P0926HT (also identified as RH926HT) serves as a foundational 8-position modular baseplate engineered for integration within Foxboro I/A Series and Foxboro Evo distributed control systems. This component provides the necessary mechanical framework and electrical backplane connectivity required for mounting 200 Series Fieldbus Modules (FBM). Designed for reliability in demanding industrial environments, the baseplate facilitates high-density I/O management in sectors such as power generation, petrochemical processing, and heavy manufacturing.

Features

• Supports up to eight 200 Series Fieldbus Modules or Fieldbus Communication Modules (FCM).
• Enables hot-swapping of modules, allowing for maintenance without interrupting process control or field wiring.
• Passive backplane design architecture for robust, long-term operational stability.
• Supports redundant 24 VDC power distribution and redundant 2 Mbps HDLC fieldbus communication.
• Integrated secure locking mechanisms and module guides to ensure electrical contact integrity in high-vibration environments.

Applications

The P0926HT baseplate is primarily utilized in distributed control system (DCS) cabinets where high availability and rapid maintenance are critical. It is suitable for applications requiring high-density I/O configurations, including process automation, remote data acquisition, and complex control loops where redundant communication and power paths are mandated.

Technical Specifications

Installation Guidelines

• Ensure the DIN rail is securely mounted and leveled prior to installing the baseplate.
• Always power down the system before inserting or removing modules from the baseplate to prevent electrical arcing or potential damage to the backplane connectors.
• Verify that all redundant power supply connections are properly terminated at the dedicated terminal blocks.
• Maintain adequate clearance around the baseplate for heat dissipation and cable routing.
• Ensure the environment is within the specified temperature and humidity ranges to prevent condensation or thermal stress.

Compliance and Certifications

This unit is manufactured to meet rigorous industrial standards, including UL/UL-C Class I Div 2, ATEX Zone 2, and CE marking for international operational compliance.

FAQ

Is this baseplate compatible with all 200 Series modules?
