F300 Megablocks are DIN-rail mounted passive hubs for Foundation™

fieldbus H1 and Profibus PA networks for general purpose, Zone 2 and

Division 2 applications. They provide a simple means of connecting field

devices to the network trunk cable, and protect the segment from spur

short circuits. 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 10V dc is present. F300 Megablocks are

available in four, eight, and twelve drop versions.
