The FS32 surge protection device prevents surges and transient

over-voltages conducted along the Trunk or Spurs of fieldbus systems

from damaging the associated electronics such as terminators, spur

blocks and the bus control equipment. Designed to fit Eaton’s latest

MTL fieldbus barrier product to protect spurs the FS32 can also be

used to protect spurs on Megablock wiring hubs. This space saving

design helps to reduce the size of junction boxes and ease installation.

The multi-stage hybrid surge protection network at the heart of

the FS32 uses a combination of solid state electronics and a gas-filled

discharge tube (GDT) to provide surge protection up to 20kA. This

impressive surge protection circuit is design to exhibit exceptionally

low line resistance and has negligible voltage drop to the spurs.

In operation the FS32 does not adversely affect the performance

or operation of the fieldbus or connected equipment, it allows signals

to pass with little attenuation while diverting surge currents safely to

earth (ground) and clamping output voltages to safe levels.

Fully automatic in operation the FS32 devices react immediately

to make sure that the equipment is never exposed to damaging

surges between lines or the lines to earth (ground). Reacting

instantaneously the FS32 redirects surges safely to earth (ground)

and then resets automatically.

The FS32 represents the next generation of surge protection to be

fitted on Foundation™ fieldbus Systems. The space saving form factor

allows the FS32 to be connected directly to the terminal receptacle on

the module carrier of the 9370 fieldbus barrier. The earth (ground) is

connected through the mounting screw in one simple operation. The

field spur cable termination block plugs directly into the FS32 allowing

fast and effective retro fitting if desired with no additional hardware

being required.

For general purpose Megablock wiring hubs FCS-MBx, FCS-MBx

SG, FCS-MBx-SG-T, F300 Range and Intrinsically Safe Megablock

wiring hubs F240 - F273 the FS32 represents a simple solution for the

fitting of surge protection with the addition of the FS32-BAR earthing

(grounding) arrangement. Furthermore the FS32 can also be used on

fieldbus power supplies such as the F800 to protect the trunk.

A 10 year no fuss warranty is available as standard for the FS32. so

if a correctly connected device should fail for any reason simply return

it for a free replacement.
