Megablock Series of Wiring Components

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 and surge 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.

Megablock 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.
