FOXBORO 0399071D I/A FBM Bus Termination Module

The FOXBORO 0399071D I/A FBM Bus Termination Module is the FBM Bus Terminator of the Foxboro I/A Series field-bus module (FBM) network — the bus termination component of the FBM bus, supplied as part of a factory-tested termination kit together with components 0303440C and 0303443B. It provides proper bus termination for reliable FBMbus communication between FBM field-bus modules and the I/A Series control processor.
Key Features

1. FBM Bus Terminator for the Foxboro I/A Series FBM bus network
2. Provides correct bus termination for FBMbus communication (FBM modules ↔ control processor)
3. Part of a factory-tested termination kit with 0303440C + 0303443B
4. Companion hardware family includes the FBM Bus Power Supply Kit (0399085B / 0303440C / 0303458A)
5. Supports reliable field-bus networking for I/A Series FBM installations
6. Foxboro product line (now Schneider Electric)

1. Confirm the kit contents (0399071D + 0303440C + 0303443B) against the I/A Series engineering documentation before installation.
2. De-energize the FBM carrier / cabinet before handling; follow ESD precautions.
3. Install the terminator at the designated FBM bus end point per the I/A Series field-bus layout drawings.
4. Verify bus termination matches the network configuration (terminator at each bus end only).
5. After power-up, verify FBMbus communication with the control processor (CP) via system diagnostics before returning to service.

1. What is the 0399071D? It is the FBM Bus Terminator of the Foxboro I/A Series FBM bus network, supplied in a termination kit with 0303440C and 0303443B — a bus termination component, not an I/O module.
2. Why does it come as a kit? The FBM bus termination requires a matched set of components (terminator + interface components).
3. Is it an analog/digital input module? No — some listings describe it as an I/O module, but the specific documentation identifies it as a bus terminator. Verify against the I/A Series drawings.
4. Which system does it belong to? Foxboro I/A Series DCS (now part of Schneider Electric).
