Product Details
The Foxboro P0926JMA, also cataloged as the P0926JMA Modular Baseplate, operates as a dedicated hardware component for structural mounting and backplane signal bus interconnection within Foxboro I/A Series DCS environments. It provides direct physical execution of modular 8-slot Field Bus Module (FBM) carrier housing and redundant power rail distribution. The assembly routes internal communication buses while regulating backplane voltage profiles to mounted I/O modules.

DCS Backplane Communication and Channel Isolation
The Foxboro P0926JMA baseplate integrates high-density multi-layer printed circuit traces engineered to maintain deterministic bus communications across all 8 module positions. Designed for Foxboro I/A Series architectures, the backplane traces deliver channel-to-channel isolation between power distribution buses and differential fieldbus communication loops. It conditions +5 VDC backplane power to preserve signal integrity and support transparent pass-through for 4-20 mA HART loop protocol field telemetry without inductive coupling.
Frequently Asked Questions
Q: Does the P0926JMA baseplate support hot-swapping of individual Field Bus Modules (FBMs)?
A: Yes, the backplane bus logic and connector pins allow live insertion and removal of individual FBM units without interrupting power or signal communication on adjacent operating slots.
Q: How is backplane power redundancy managed across the 8 slots of the P0926JMA?
A: The baseplate features integrated dual power distribution rails that route primary and secondary +5 VDC supply buses across all slots, ensuring continuous operation if one power feed degrades.
Field Installation Guidelines
- Mount the P0926JMA baseplate horizontally onto standard DIN rails, ensuring all retention clamps latch tightly against the rail base.
- Verify that adjacent baseplates connect via dedicated HDLC interface cables before applying system backplane power.
- Connect the primary system ground strap to the dedicated grounding stud on the baseplate frame to ensure full EMI/RFI shielding protection.
- Align module keyways before inserting FBM units into any of the 8 slots to prevent pin bending on the +5 VDC backplane connector headers.
