Features:
- Fieldbus bridge: Connects baseplate-mounted I/A Series Fieldbus Modules to a control station over fiber.
- Protocol conversion: Translates the 2 Mbps module Fieldbus to a 10 Mbps fiber-optic trunk and back.
- Network reach: Supports distances up to 2 km through the documented compatible hub architecture.
FCM10Ef extends an I/A Series FBM grouping over fiber while maintaining the control-station communication path.
The module uses multimode fiber with ST connections and reports operating and traffic states through six front indicators.
Integration planning covers the control station, hub, redundancy arrangement, baseplate power, enclosure and fiber route.
Apter Power provides documentation, quotation and procurement support for the Invensys FCM10Ef I/A Series Fiber-Optic Fieldbus Communications Module.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Control-station connection: FCM10Ef works with supported multiport fiber-optic converters or hubs on an optionally redundant 10 Mbps trunk Fieldbus.
- Group capacity: Up to six groupings of FCM10Ef modules and FBMs can be connected through the hub architecture.
- FBM capacity: A control station can support up to 120 FBMs, with the practical total governed by selected scan periods.
- Redundancy: One FCM10Ef serves a non-redundant grouping; a redundant grouping requires a pair.
- Recommended cable: Customer-supplied 62.5/125 µm graded-index multimode glass fiber with 0.275 numerical aperture.
- Termination: The module uses ST-type fiber connectors, and duplex cable is recommended.
- Loss budget: Maximum allowable cable loss is 1 dB/km at 1300 nm and 3.6 dB/km at 850 nm.
- Redundant routing: A redundant installation uses four fibers: two transmit and two receive paths.
- Input supply: 24 V dc, +5%/-10%, supplied through the I/A Series baseplate.
- Consumption: Maximum power use and heat dissipation are both 7 W.
- Operating range: -20°C to +70°C with 5% to 95% noncondensing relative humidity.
- Installation environment: The specification covers ISA Class G3 contamination, pollution degree 2 and mounting through the supported baseplate arrangement.
- Distributed FBM networks: FCM10Ef is used when remote Fieldbus Module groups must connect to an I/A Series control station across a fiber link.
- Fiber advantages: The link supports long runs and helps avoid electrical ground-loop, lightning and electromagnetic-interference paths between locations.
- System boundary: FCM10Ef is not a general-purpose Ethernet switch; it belongs in the documented I/A Series Fieldbus architecture.
- Approval boundary: Division 2, Zone 2 and CE/ATEX claims depend on the listed enclosure system, connected processor, certificate and site conditions.
