Crouse-Hinds series MTL Megablock™ is a DIN-rail mounted passive hub designed for use in FOUNDATION™ fieldbus H1 and Profibus PA networks. 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.

• F2xx-IS models: Intrinsically Safe Megablocks for Zone 1 applications
• F2xx-XE models: Megablocks for Zone/Div 1 applications
