Product Overview

The Foxboro FEM100 (P0973CA) functions as a high-density Fieldbus Expansion Module for the I/A Series Distributed Control System (DCS). This 100% Brand New original module significantly increases the I/O capacity of a Field Control Processor 270 (FCP270) by providing four additional Expanded Fieldbuses. Each bus accommodates up to thirty-two 200 Series Fieldbus Modules (FBMs), allowing a single FCP270 to manage up to 128 FBMs through the FEM100 interface. It acts as the critical high-speed data bridge for large-scale industrial automation projects in oil & gas, power generation, and chemical processing.

Technical Specifications

Engineering Advantages

• Massive I/O Scalability: The FEM100 removes the physical constraints of standard processor baseplates. By adding up to four expanded buses, it enables the control of extensive field device networks without requiring additional expensive control processors.

• High-Speed Deterministic Data: With a 2 Mbps transmission rate, the module ensures the FCP270 receives real-time process data from the 200 Series FBMs. This throughput maintains the accuracy of high-speed control loops and prevents communication bottlenecks.

• Extended Environmental Durability: The P0973CA operates across a wide temperature range (-20 to +70°C). This ruggedized specification allows for installation in remote instrument enclosures where environmental control may be inconsistent.

• Low Power Signature: Consuming only 2.2 W at maximum load, the module minimizes the thermal footprint within the control cabinet. This helps maintain a lower internal temperature, which extends the lifespan of surrounding electronics.

• Modular Integration: The unit snaps directly onto specialized expansion baseplates (P0973CG/CN). This modularity simplifies system upgrades and allows for rapid "hot-replacement" if the network architecture needs immediate adjustment.

FAQs

• How many FBMs can a single FEM100 support?

  The FEM100 provides four Fieldbus ports. Each port supports 32 modules, allowing the P0973CA to manage a total of 128 200 Series Fieldbus Modules.

• Does the FEM100 require a specific processor?

  Yes. The FEM100 is specifically designed to work with the Field Control Processor 270 (FCP270). Ensure your system uses the correct processor model before deploying this expander.

• Can I mount the FEM100 directly to a DIN rail?

  No. You must mount the FEM100 onto an Expansion Baseplate (such as the P0973CG or P0973CN), which then attaches to the vertical DIN rail.
