Megablock Series Of Wiring Hubs

Supplier: MTL Instruments

Megablocks are DIN-rail mounted passive hubs designed for use in FOUNDATION fieldbus™ and Profibus-PA segments. They can connect 2, 4, 8, 10 or 12 field devices to the network trunk cable and can also provide short circuit and over voltage 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. The SpurGuard™ option provides short circuit protection for the segment.

Hazardous area approvals permit installation in a variety of configurations in Zone 1 or 2 and Division 1 or 2. Within Zone 2 or Division 2, Megablocks may be installed as part of non-sparking (non-arcing) or energy-limited (non-incendive) circuits.

Additionally, SpurGuard™ versions have energy-limited spur connections, even if the trunk is classified as 'non-sparking', when fed for example from an MTL5995 or FPS fieldbus power supplies.

Because a fieldbus segment must be terminated at the ends, why not use a Megablock with an integral terminator or, alternatively, a separate DIN-rail mounting terminator.
