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.
