Product Details
Configured for expanded I/O scalability in I/A Series control networks, the Foxboro P0973CA, also cataloged as the FEM100 Fieldbus Expansion Module, provides direct electrical execution for four additional fieldbus segments connected to the FCP270 Field Control Processor. This module facilitates the communication between the primary control processor and up to 128 distributed 200 Series Fieldbus Modules (FBMs) across the expanded architecture.

Process Control and Communication Connectivity
The FEM100 manages the deterministic exchange of data between the FCP270 processor and remote 200 Series DIN FBMs. By expanding the local fieldbus capacity, the module supports complex control loops that require high-density I/O distributions while maintaining the 2 Mbps transmission rate standard for the 200 Series. The module architecture is designed for integration with specific expansion baseplates (P0973CG/CN), which provide the physical interface for power and data routing. Each of the four expanded segments operates independently, ensuring that faults in one fieldbus segment do not impact the communication throughput of the other segments.
Frequently Asked Questions
Q: Can the FEM100 be mounted directly onto a standard DIN rail without an expansion baseplate?
A: No. The FEM100 must be installed onto a compatible two-slot (P0973CG) or four-slot (P0973CN) expansion baseplate, which handles the necessary power and fieldbus signal distribution.
Q: Is the FEM100 compatible with older 100 Series Fieldbus Modules?
A: No. The FEM100 is specifically designed for 200 Series DIN Fieldbus Modules and does not support the protocol or physical layer requirements of legacy 100 Series hardware.
Field Installation Guidelines
- Mount the required expansion baseplate (P0973CG or P0973CN) securely onto the vertical DIN rail according to standard mechanical assembly practices.
- Ensure the baseplate is properly grounded to the cabinet common to minimize EMI effects on the 2 Mbps fieldbus transmission.
- Slide the P0973CA module into the assigned baseplate slot; verify that the rear connector pins are fully mated and the locking mechanism is engaged.
- Route fieldbus expansion cabling through shielded conduits; ensure cable length adheres to the limits defined in the relevant PSS documentation to prevent signal timing violations.
- Verify that the input voltage is within the specified 21 V dc to 26 V dc range before enabling power to the expansion segment.
