Description
Product Description
FOXBORO FCM10EF is a fieldbus communications module of Foxboro I/A Series DCS, dedicated to connecting DIN rail – mounted Fieldbus Modules (FBMs) with I/A Series control stations through a high – speed, optionally redundant 10 Mbps Ethernet trunk fieldbus. FOXBORO FCM10EF can convert 10 Mbps Ethernet signals used by the control station into 2 Mbps signals for FBMs and vice versa, while also providing galvanic isolation between the 10 Mbps Ethernet trunk fieldbus and the 2 Mbps module fieldbus. FOXBORO FCM10EF is designed to be used in pairs for redundancy, and a single module or a redundant pair can support up to 30 FBMs, which makes it suitable for medium – to large – scale industrial automation systems with high requirements for communication reliability. FOXBORO FCM10EF has a compact and rugged extruded aluminum exterior, which can physically protect the internal circuits in harsh industrial environments. FOXBORO FCM10EF supports up to 30 redundant pairs connected to the Ethernet trunk fieldbus, enabling flexible system expansion. FOXBORO FCM10EF is easy to install on DIN rails or rack – mounted backplanes, and is compatible with various FBMs of the I/A Series, facilitating seamless integration into existing control systems.

Application Fields and Cases
FOXBORO FCM10EF is widely used in process industries, such as:
- Petrochemical Industry: Connects FBMs with control stations to monitor and control key parameters like temperature, pressure and flow in refineries and chemical plants.
- Power Generation: Ensures reliable data communication between field devices and DCS in thermal power plants and renewable energy facilities, supporting efficient power generation and grid connection.
- Water and Wastewater Treatment: Integrates with FBMs for process control of water treatment units, improving water quality and treatment efficiency.
Case Example: A large – scale refinery in the Middle East adopted FOXBORO FCM10EF redundant pairs to upgrade its I/A Series DCS communication network. FOXBORO FCM10EF connected 28 FBMs distributed in different process areas, realizing real – time data transmission and control. After the application of FOXBORO FCM10EF, the communication failure rate of the system decreased by 85%, the maintenance time was reduced by 40%, and the continuous and stable operation of the refinery was guaranteed.

Selection Recommendations and Precautions
Selection Recommendations
- When selecting FOXBORO FCM10EF, consider the number of FBMs, the need for redundant communication and the compatibility with the existing I/A Series DCS.
- For mission – critical systems, use FOXBORO FCM10EF in redundant pairs to maximize communication reliability.
- Ensure that the power supply voltage is within the range of 24 V DC +5% / -10% to avoid damage to the module.
Precautions
- Do not operate FOXBORO FCM10EF beyond the specified temperature range (-20°C to +70°C) and humidity range (5% – 95% RH, non – condensing) to prevent performance degradation or damage.
- Install and wire FOXBORO FCM10EF in accordance with FOXBORO’s guidelines to ensure proper galvanic isolation and signal integrity.
- Use only genuine FOXBORO accessories and compatible FBMs to maintain system compatibility and safety.
- Regularly check the status indicators of FOXBORO FCM10EF for timely detection and troubleshooting of communication problems.
