Crouse-Hinds series MTL AS-i Megablocks are DIN-rail mounted passive hubs for the AS-i network. They connect several AS-i devices to the network trunk cable and provide short circuit protection to the segment. The AS–i Megablock itself does not contain an AS–i chip or communicate over the AS–i network, so it consumes no network communication resources (bandwidth, slave addresses, etc.). They are used to interconnect AS–i master and slave devices that do contain AS–i chips.

Megablocks minimize hand wiring and allow individual devices to be added to and removed from the segment without disrupting network communication. The integrated SpurGuard™ provides short circuit protection for the segment.

Two models are available

• A101: 4-drop AS-i Megablock with integrated SpurGuard™ short circuit protection
• A103: 8-way AS-i Megablock with integrated SpurGuard™ short circuit protection
