Foxboro FCM10EF Fieldbus Communications Module

Foxboro FCM10EF Fieldbus Communications Module

Description

The FCM10Ef Fieldbus Communications Module is a fiber optic communications interface which allows the DIN rail mounted Fieldbus Modules (FBMs) to communicate with the I/A Series control station over extended distances using fiber optic cabling. The FCM10Ef modules provide expanded networking, easy customization, and greater overall cabling distances in a fiber optic network. This configuration is ideally suited for sites in which groups of FBMs are to be spread apart over greater distances.

FCM10Ef modules are used with multiport fiber optic converters (hubs), which connect to the I/A Series control station via the high-speed, optionally redundant 10 Mbps Ethernet trunk Fieldbus.

Up to six groupings of baseplate-mounted FCM10Ef modules and FBMs can be linked to each optionally redundant multiport fiber optic converter (hub), for a maximum of 120 FBMs per I/A Series control station (depending on selected scan periods). To support redundancy, a pair of FCM10Ef modules must be used for each FBM grouping. In non-redundant configurations, only a single FCM10Ef is required for each grouping.

Signal transmission distances up to 2 km (1.24 mi) are possible between the FCM10Ef modules and the multi-port fiber optic converters (hubs), providing for wide distribution of the FBM equipment groupings.

Extended transmission distances, using fiber optic cabling, are also possible within the groupings, and between the multiport fiber optic converter (hub) and the I/A Series control station.
