More Information:
Overview
A MegablockTM is a DIN rail mounted passive hub for FoundationTM fieldbus
networks. Also called bricks' or couplers', Megablocks connect several
field devices to the network trunk cable and provide spur short circuit
protection for the segment. With over 500,000 device connections
installed, the simple circuitry of the Megablock delivers the highest
network availability. With more complex circuit designs the risk of
product failure may be greater than the risk of a spur short circuit.
Hazardous Areas
The F300 Megablock is designed for general purpose, Zone 2 and Division 2
hazardous area applications. The high energy trunk can be powered by a
wide range of fieldbus power supplies. The ability to conduct live
maintenance - such as replacement of field devices in hazardous areas is
desirable. Live connection and disconnection of fieldbus spurs without a
gas clearance certificate is allowed with Ex ic and non-incendive field
devices. Where live-working of the spurs is not required, Ex d
(flameproof) or Ex nA (normally non-sparking) field devices may be
selected.
Easy to install and maintain
Megablocks minimize hand wiring and allow individual devices to be added
to and removed from the segment without disrupting network communication.
The pluggable connectors are screw secured ensuring reliable connections
even in a high vibration environment. Attention to detail includes the
+/S/- fieldbus connections to prevent intermittent connection to an
adjacent terminal causing fieldbus failure. A green power LED on each
unit indicates whether at least 10V of DC power is present.
The 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 may be mounted in the Trunk-out connection to
provide termination when the Megablock is located at the end of the
fieldbus segment. It can be removed when the segment is extended, to
ensure correct termination.
Surge Protection
Pluggable surge protection components for the fieldbus trunk and
individual spurs are available as an option reducing the installed cost
of providing surge protection on fieldbus networks.
