FBI10E (P0972AJ / P0972A7)

Basic Information

Model: FBI10E (Part Numbers: P0972AJ, P0972A7)

Manufacturer: Foxboro (Schneider Electric)

Type: Fieldbus Isolator/Interface Module

System: I/A Series DCS (EcoStruxure Foxboro)

Status: Active / Spare (current generation)

Key Features

Dual-Speed Conversion: Bridges 10 Mbps Ethernet (control side) and 2 Mbps HDLC (field side)

High Isolation: 1500 V isolation breaks ground loops and suppresses surges/EMI

Redundancy Ready: Supports redundant fieldbus and redundant power for high availability

Compact & Rugged: Half-size Y-module fits standard I/A Series enclosures (4/8/16/32)

Diagnostics: LED indicators for power, communication, and fault status

Hot-Swappable: Online replacement in redundant configurations

Typical Applications

I/A Series DCS: Connecting CP60 controllers to FBM I/O modules in large process plants

Process Industries: Chemical, petrochemical, oil & gas, power, water treatment

Noise Environments: Installations with high EMI/RFI or potential ground potential differences

Migration Projects: Integrating legacy 2 Mbps FBMs with modern 10 Mbps Ethernet-based CP60 systems

Compatibility Notes

FBI10E: Isolator/converter (10 Mbps ↔ 2 Mbps)

FBCxx: 200 Series FBMs (e.g., FBC07, FBC09, FBC21) – connect via FBI10E to CP60

CP60: Primary controller for I/A Series DCS – requires FBI10E for FBM I/O connection
