RH914YZ Foxboro FCM2F2 2km Multimode Communication Card

Product Overview

The Foxboro FCM2F2 RH914YZ functions as a high-speed Fiber-Optic Fieldbus Communication Module for the Foxboro I/A Series Distributed Control System (DCS). This module extends the reach of the 200 Series Fieldbus beyond traditional copper cabling limits, allowing for the remote installation of Fieldbus Modules (FBMs) in distant plant areas. By converting electrical fieldbus signals into light pulses, the FCM2F2 enables long-distance data transmission while providing total electrical isolation. We provide this module as 100% brand new and original, ensuring your critical network infrastructure meets factory specifications for high-availability performance.

Technical Specifications

Engineering Advantages

• Complete EMI/RFI Immunity: The FCM2F2 utilizes fiber-optic medium to transmit data, making the communication link completely immune to electromagnetic and radio frequency interference. This eliminates the data corruption risks associated with running control cables near high-voltage switchgear or large motors.

• Extended Reach for Remote I/O: This module overcomes the distance limitations of standard copper fieldbus segments. It supports individual segment lengths of up to 2 km and a total network chain of 20 km, facilitating the centralization of control rooms while keeping I/O modules close to the actual process equipment.

• Lightning and Surge Protection: Because fiber-optic cable does not conduct electricity, the FCM2F2 acts as a natural surge barrier. It protects sensitive DCS baseplates from lightning strikes and ground potential rises that often travel through traditional copper cabling in outdoor or expansive industrial sites.

• Robust Hardware Construction: Foxboro houses the FCM2F2 in an extruded aluminum casing to shield the internal circuitry from physical damage and industrial contaminants. The unit meets ISA S71.04 Class G3 standards, ensuring reliable operation in corrosive chemical and offshore environments.

• Non-Disruptive Maintenance: The module features a hot-swappable design. Technicians can replace an FCM2F2 without powering down the baseplate or interrupting the communication of other modules in the rack. Integrated LEDs provide real-time diagnostics for fiber link integrity and module health at a glance.

FAQs

How do I configure redundancy with the FCM2F2?

To achieve a fault-tolerant configuration, install two FCM2F2 modules into the dedicated slots of a baseplate. The modules will operate in a redundant pair; if one fiber link or module fails, the system automatically switches to the secondary unit without dropping communication.

What type of fiber cable does the RH914YZ require?

The RH914YZ is optimized for multimode fiber with a 62.5 µm core and 125 µm cladding. It utilizes standard ST-type connectors for secure, industrial-grade optical termination.

Can I mix fiber and copper segments in the same fieldbus network?

Yes. The FCM2F2 acts as the bridge between the electrical fieldbus on the baseplate and the fiber-optic cabling. You can use fiber for long-distance runs between buildings and copper for local communication within the same cabinet.

Does this module come with a factory warranty?

Every Foxboro FCM2F2 RH914YZ we ship is 100% brand new and original stock. Each unit includes a 12-month factory warranty and has passed rigorous factory-level testing for optical signal strength and data throughput.
