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. Features * 4, 8 or 12 device connections * Single-piece Trunk In/Out connector simplifies installation and maintenance * Pluggable trunk and spur surge protection option * Choice of rising cage clamp screw or spring clamp terminals for spurs * Locate Megablock in Zone 2 or Division 2 * Connect to non arcing, non incendive or Ex ic devices in Zone 2/Division 2 * Connect to Ex d, explosionproof devices in Zone 1/Division 1 See also the F200 IS Megablock for Intrinsically Safe applications and F200-XE Megablock for Zone 1 mounting when connected to flameproof (Ex d) field devices.
