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.
