2. Key Features
The FEM100 is a dedicated fieldbus expansion module designed for Foxboro I/A Series DCS systems, integrating fieldbus signal expansion, data transmission and fault monitoring functions. It supports both redundant and non-redundant configurations: redundant use requires pairing FEM100 modules to form a fault-tolerant pair, ensuring uninterrupted fieldbus communication even when a single module fails, while non-redundant configuration uses a single FEM100 for fieldbus expansion. Its communication interface is immune to electrical noise such as EMI, RFI, and lightning, making it suitable for areas with rotating machinery, arc welders, high-voltage wires, or outdoor areas exposed to lightning hazards. The FEM100 has electrical isolation to prevent voltage differences and ground loops, protecting the system from electrical interference and damage. It can be removed and replaced from the baseplate without powering down the system, minimizing maintenance downtime. It can connect to the central controller via fieldbus or fiber optic cables, supporting extension of fieldbus communication distance and flexible expansion of system I/O capacity.
3. Installation & Wiring
The FEM100 (Part Number: P0973ZA) is installed on standard baseplates, which include signal connectors for fieldbus, power, and I/O cables. A single baseplate can support up to eight FBMs, or a combination of FBMs and FEM100 modules for system expansion. When connecting two baseplates with fiber optic cables (redundant configuration), each baseplate requires a matching FEM100 module for signal expansion and transmission; non-redundant configuration requires one FEM100 per baseplate to realize fieldbus expansion. Baseplates within 60 meters can be connected via standard twisted-pair cables without additional fiber optic modules. Fiber optic cables for the FEM100 are purchased separately by the customer, and must use ST-type connectors (multi-mode graded-index glass fiber, 62.5/125 µm core/cladding, 0.275 NA) as specified; non-compliant cables are not allowed. The FEM100 is installed in a rugged extruded aluminum housing, suitable for G3-level harsh industrial environments, and can be mounted in control cabinets or on-site near process equipment. During installation, anti-static measures should be taken to avoid damage to the module, and attention should be paid to ensuring the compatibility of the connected FBM modules (supports both 100-series and 200-series FBMs).
4. Application
The FEM100 (Part Number: P0973ZA) is widely used in Foxboro I/A Series DCS systems, suitable for industrial control scenarios such as power, chemical, oil and gas, and water treatment industries that require fieldbus expansion and distributed I/O deployment. It is particularly applicable to areas with strong electromagnetic interference, lightning hazards, or large-scale I/O expansion needs. It supports connection of up to 32 FBM modules per module, enabling flexible expansion of system I/O capacity and remote installation of FBM modules near factory processes, reducing the length of field wiring and improving system reliability. Equipped with a stable processor, it ensures fast and reliable data transmission between FBM modules and the central controller, meeting the needs of industrial control systems for real-time data acquisition and command issuance. Its noise immunity and electrical isolation make it ideal for harsh industrial environments, ensuring stable and reliable operation of the fieldbus expansion system.

6. Notes
The FEM100 (Part Number: P0973ZA) is exclusively designed for Foxboro I/A Series DCS systems, compatible with 100-series and 200-series FBM modules and standard baseplates. Redundant configuration requires pairing FEM100 modules to form a fault-tolerant pair, ensuring fault tolerance and zero downtime of the fieldbus expansion system. Fiber optic cables for FEM100 must meet the specified requirements (multi-mode graded-index glass fiber, 62.5/125 µm core/cladding, 0.275 NA, ST-type connectors) to avoid signal loss or communication failure. The FEM100 supports hot-swap replacement, which can be completed without shutting down the system. It operates on a 24V DC redundant power supply with a single module power consumption ≤6W, supporting a wide voltage input range of 18-32V DC. For optimal performance, install the FEM100 in a well-ventilated area, away from direct sunlight and extreme temperature fluctuations, and ensure the installation environment meets the 0℃~60℃ operating temperature requirement.
