The F2xx-IS MTL Intrinsically Safe (IS) Megablocks are DINrail mounted passive hubs for Foundation™ fieldbus networks.
They connect several IS field devices to the network IS trunk cable and provide short circuit protection to the segment.
Megablocks minimize hand wiring and allow individual IS devices to be added
to and removed from the segment without disrupting network communication.
