More description MTL F312 megablock range

F300 Megablocks are DIN-rail mounted passive hubs for Foundation™ fieldbus H1 and Profibus PA networks for general purpose, Zone 2 and Division 2 applications. They provide a simple means of connecting field devices to the network trunk cable, and protect the segment from spur short circuits. Megablocks minimize hand wiring and allow individual devices to be added to and removed from the segment without disrupting network communication. A green power LED on each unit indicates whether at least 10V dc is present. F300 Megablocks are available in four, eight, and twelve drop versions.

The black Trunk In/Out pluggable connector allows replacement of a Megablock without breaking the trunk connection to other devices on the fieldbus segment. The F97 terminator supplied should be mounted in the Trunk-out connection to provide termination when the Megablock is located at the end of the fieldbus segment; alternatively,if the segment is extended, it can be removed to ensure the correct termination is maintained.

Spur connections to the Megablock are made using pluggable, grey,screw-terminal or spring clamp terminal connectors. Wire terminations can be made to the individual connectors before plugging them into the Megablock. Devices can then be connected and disconnected easily during commissioning. After commissioning, retaining screws are tightened to secure each connector to the Megablock. Separate numbered connections are provided for each spur drop.

MTL F300 megablock range Passive hubs for general purpose, zone 2 & division 2 fieldbus networks SpurGuard™ is a device-port, short circuit protection technique that minimizes susceptibility to single points of failure. The F300 Megablock has built-in SpurGuard™ protectors that prevent a short circuit in any of the individual field devices or spur cable runs, from bringing down the entire fieldbus segment. A red LED near each spur connection indicates when a spur is shorted and hence in “overcurrent” mode.

The optional FS32 modules can provide surge protection for the F300 products on both the trunk and spur terminals. These pluggable modules are simple to fit in a new installation, or as a retrofit option.A range of MTL Process Junction Boxes in stainless steel and carbonloaded, glass-reinforced polyester are available for mounting Megablock wiring components. They offer plenty of space for termination andwiring, making it easy to install and maintain the fieldbus system.
