FBM232 P0926GW high-performance FOUNDation Fieldbus H1 interface module

The FBM232 P0926GW is a high-performance FOUNDation Fieldbus H1 interface module developed by Foxboro for its I/A Series Distributed Control System (DCS). It serves as a critical bridge between the DCS and intelligent field devices (e.g., transmitters, valve positioners) that communicate via the FOUNDATION Fieldbus H1 protocol, enabling bidirectional digital communication and centralized management of field equipment. Below is its detailed information:

1. Core Technical Specifications

Parameter	Details
Communication Protocol	FOUNDATION Fieldbus H1 (31.25 kbps), fully compliant with IEC 61158 standards.
Fieldbus Ports	2 independent H1 ports (redundant configuration supported), each capable of connecting up to 16 field devices (max. 32 devices per module with proper power budgeting).
Power Supply to Field Devices	Provides intrinsic safety (IS) power via H1 ports (optional, depending on configuration):- Output voltage: 12–32V DC (nominal 24V DC).- Maximum current per port: 150mA (supports powering field devices without external power supplies).
Isolation Rating	Port-to-port isolation: ≥500V AC (1 minute).Module-to-DCS backplane isolation: ≥2500V AC (1 minute), preventing ground loops and electromagnetic interference (EMI) in industrial environments.
Operating Temperature	-40°C to 70°C (suitable for extreme industrial sites, including hazardous areas with proper enclosures).
Power Consumption	24V DC ±10% (typical), power consumption ≤10W (compatible with I/A Series rack power modules like P0916JP).
Physical Dimensions	Standard I/A Series FBM form factor: approx. 120mm × 100mm × 50mm (H×W×D), ensuring seamless integration with existing DCS racks.
