FCS-MBx-SG Megablock series*

1 technical datasheet technical datasheet FCS-MBx-SG Megablock series* passive hubs for general purpose, Zone & Division fieldbus networks Megablocks are DIN-rail mounted passive hubs for Foundation fieldbus networks. They connect several field devices to the network trunk cable and provide short circuit protection to the segment. Megablocks minimize hand wiring and allow individual devices to be added to and removed from the segment without disrupting network communication. A green power LED on each unit indicates whether at least 9V dc is present. Megablocks are available in two, four, eight, ten and twelve drop versions. Multiple Megablocks are easily wired to one another to allow larger segments to be constructed. Megablocks are available with an integral terminator making them ideal for a star or "chickenfoot" topology, where several devices are connected at a single field junction box. Separate Megablock Terminators are also available, whch may be wired easily to any Megablock. Megablocks having a built-in terminator are clearly marked ('T') for easy identification by field personnel. Connections to the Megablock are made using pluggable, screw-terminal type connectors. This allows wire terminations to be made to the individual connectors which are then plugged into the Megablock. Devices can then be connected and disconnected easily during commissioning. After commissioning, retaining screws are tightened to secure each connector to the Megablock. connections for the fieldbus home-run/ trunk cable are easily identified by their black connectors. Separate numbered connections are provided for each spur drop. SpurGuard is a device-port, short circuit protection technique that minimizes susceptibility to single points of failure. Megablocks are available with built-in SpurGuard protectors that prevent a short circuit in any of the individual transmitters or spur cable runs, from bringing down the entire fieldbus segment. A red LED near each spur connection indicates when a spur is shorted and hence in "over-current" mode. FCS-MBx-SG hazardous area approvals permit installation in a variety of configurations in Zone and Division hazardous areas. FCS-MBx and FCS-MBx-SG Megablocks may be installed with non-sparking (non-arcing) trunk and spur connections. Additionally, with FCS-MBx-SG SpurGuard versions, the trunk may be nonsparking (non-arcing) with non-incendive spur connections, when fed from suitable fieldbus power supply types. See the Fxx Megablock datasheet for Zone and Division hazardous areas applications. Additionally, for applications without SpurGuard short circuit protection, the FCS-MBx is certified for installation in intrinsically safe, fieldbus circuits in Zone hazardous areas. To select the Megablock for your application see the Ordering Information section of this document. * including models without Spurguard EPS MBx Rev 00 [email protected]

Megablocks are removed from the DIN rail using a flat blade screwdriver to release the mounting platform. Use of DIN rail end stops is recommended to prevent sliding in vertical installations. Four, eight and ten port Megablocks have labeling areas so that segments can be easily identified according to plant standards. MTL have a wide range of standard junction box designs for use with Megablocks. See the data sheet for the range of Process JBs.

Twelve field devices are connected to a twelve-drop Megablock, which is mounted in a field junction box. The trunk connector on the Megablock is wired to the segment trunk cable that leads to the control room or marshalling panel where the power supply and second terminator are located. Grounding To prevent ground loops, a fieldbus segment should only be grounded at one point. This is usually done by grounding the cable shield at the control room end of the segment. If a permanent segment ground connection in the field is desired, this can be achieved by wiring the shield terminal on one of the Megablock trunk connectors to a suitable earth ground instead of wiring it to the shield terminal on the Megablock Terminator.
