The P0926JM is the core internal hardware assembly (PCBA) for the FBM231 Discrete I/O Module and various FCM (Fieldbus Communication Modules) within the Foxboro I/A Series system.
Unlike a complete encased module, the P0926JM represents the internal electronic backbone. It is specifically engineered to interface with the B-Position slot on Foxboro Modular Baseplates (such as the RH924YF and P0926KE). This component is essential for repair and maintenance, allowing technicians to restore module-to-backplane communication without replacing the entire module housing or baseplate infrastructure.
Core Function: Provides the high-speed 32-channel discrete signal routing and bus interface logic.
B-Position Logic: Specifically designed to occupy the B-Position within the modular baseplate architecture, managing the primary/redundant data path.
Optical Isolation: Integrated 1500 V AC galvanic isolation to protect the DCS control network from field-side electrical surges.
Environmental Protection: Features ISA-S71.04 Class G3 conformal coating (as visible on the board surface), ensuring maximum resistance to corrosive industrial gases ($H_2S$, $SO_2$, etc.).
| Feature | Specification |
| Part Number | P0926JM |
| Functional Model | FBM231 / FCM Series |
| Interface Slot | B-Position (Modular Baseplate Backplane) |
| Signal Level | 24 V DC Discrete |
| Board Finish | G3 Conformal Coated (Anti-Corrosion) |
| Component Type | Internal PCBA (Board Only) |
Q1: Is the P0926JM a complete Field Bus Module?
A1: No. It is the internal electronic assembly (PCBA) found inside FBM231. This listing is for the bare board as shown in the photos, used primarily for hardware-level repairs.
Q2: What does "B-Position" mean in the title?
A2: On a Foxboro Modular Baseplate, the modules must connect to specific internal bus positions. The P0926JM is the hardware interface that physically and logically connects to the B-Position pins.
Q3: Can I use this to repair a failed FBM231?
A3: Yes. This is the most cost-effective way to fix a module with internal electronic failure while reusing your existing plastic housing and handles.
Replacement Protocol: Swapping the P0926JM should be done in an ESD-safe environment. The board fits precision-keyed slots within the FBM/FCM housing.
Redundancy Note: Ensure the partner module in redundant pairs is healthy before performing an internal board swap to maintain process continuity.
Visual Inspection: The high-quality G3 coating on this P0926JM ensures it can be deployed in harsh "near-process" cabinets.
