Eaton’s Freedom starters and contactors feature a compact, space-saving design,

using state-of-the-art technology and the latest in high strength, impact and

temperature resistant insulating materials. In addition to the bimetallic overload,

Eaton also offers a series of electronic overload relay (C440) available as a

standalone unit and assembled with Freedom contactor. These adjustable bimetallic

ambient compensated contactors are designed for use with CE or CN non-reversing

and reversing contactors. They have interchangeable heater packs and are available

in four sizes for overload protection up to 900 hp, reducing the number of different

contactor/overload relay combinations that have to be stocked.

They also feature a full line of snap-on accessories common to both IEC and NEMA devices.

Freedom series (NEMA)

Eaton’s Freedom NEMA AN19 starter series combines exceptional Freedom contactor ratings

with the C440 electronic overload’s superior motor protection features.

AN19 starters can be monitored in real-time over communications, allowing for reduced

troubleshooting efforts and downtime.

Crouse-Hinds series MTL Megablock™ is a DIN-rail mounted passive hub

designed for use in FOUNDATION™ fieldbus H1 and Profibus PA networks.

Megablocks minimize hand wiring and allow individual devices to be added

to and removed from the segment without disrupting network communication.

The SpurGuard™ option provides short circuit protection for the segment.

Hazardous area approvals permit installation in a variety of configurations in

Zone 1 or 2 and Division 1 or 2. Within Zone 2 or Division 2. Megablocks may

be installed as part of non-sparking (non-arcing) or energy-limited (non-incendive) circuits.

INSTALLATION

Megablocks can be mounted vertically or horizontally using 35

mm DIN rail within a suitable enclosure, such as a field junction

box. Megablocks are removed from the DIN rail using a flat blade

screwdriver to release the mounting platform. Use of DIN rail end

stops is recommended to prevent sliding in vertical installations. The

four, eight, ten and twelve port Megablocks have labeling areas so

that segments can be easily identified according to plant standards.

MTL have a wide range of standard junction box designs for use with

Megablocks. See the data sheet for the range of Process JBs.

Shown above is an example of a common Fieldbus segment topology.

Twelve field devices are connected to a twelve-drop Megablock,

which is mounted in a field junction box. The trunk connector on

the Megablock is wired to the segment trunk cable that leads to the

control room or marshalling panel where the power supply and second

terminator are located. The example shows the

increased safety (Ex em) version connected to a general purpose

fieldbus power supply.

GROUNDING

To prevent ground loops, a fieldbus segment should only be grounded

at one point. This is usually done by grounding the cable shield at the

control room end of the segment. If a permanent segment ground

connection in the field is desired, this can be achieved by wiring

the shield terminal on one of the Megablock trunk connectors to a

suitable earth ground instead of wiring it to the shield terminal on the

Megablock Terminator.

Fieldbus Connection System (FCS) wiring blocks are protected by U.S.

Patents 6.366.437. 6.369.997 and 6.519.125.

SpurGuard™ is a device-port, short circuit protection technique

that minimizes susceptibility to single points of failure. The

Megablocks come with built-in SpurGuard™ protectors that prevent

a short circuit in any of the individual transmitters or spur cable runs

from bringing the entire fieldbus segment down. A red LED near

each spur connection indicates that a spur is shorted and is in “over

current” mode.

For applications using flameproof certified devices, the F2xx-XE

Megablocks are designed to meet the requirements for increased

safety for installation in an Ex e junction box in Zone 1. See the F300

Series Megablock datasheet for applications in safe areas, Zone 2

and Division 2 hazardous areas.

To select the Megablock for your application see the Ordering

Information section of this document.

Passive Hubs for Zone 1 Fieldbus Networks

Megablocks are DIN-rail mounted passive hubs for Foundation™

fieldbus networks. They connect several field devices to the network

trunk cable and provide short circuit protection to the segment.

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 9V dc

is present. F2xx-XE Megablocks are available in four, eight, ten and

twelve drop versions. Multiple Megablocks are easily wired to one

another to allow larger segments to be constructed.

Megablocks are available with an integral terminator making

them ideal for a star or “chickenfoot” topology where several devices

are connected at a single field junction box. Separate Megablock

Terminators are also available, whch may be wired easily to any

Megablock. Megablocks having a built-in terminator are clearly

marked (‘T’) for easy identification by field personnel.

Connections to the Megablock are made using pluggable, screw

terminal type connectors. This allows wire terminations to be

made to the individual connectors which are then plugged 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.

Trunk connections for the fieldbus home-run/ trunk cable are easily

identified by their black connectors. Separate numbered connections

are provided for each spur drop.
