FCS-MBx-SG Megablock range*

Passive hubs for general purpose, Zone 2 & Division 2 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 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, which may be wired easily to any

Megablock. Megablocks having a built-in terminator are clearly marked

(‘T’) for easy identification by field personnel.
