The TP32 surge protection device is
specifically designed to protect process
transmitters and devices on Fieldbus
systems. The TP32 builds on the high
specification of the acclaimed TP48 range to
provide a level of surge protection for fieldbus
transmitters that is well in excess of the
optional transient protection available from
some transmitter manufactures.
The all important earth connection is
made via the casing of the transmitter
negating the need for a separate earth
connection or ground stake at the
transmitter. In operation, the TP32 makes
sure that the transmitter electronics are
never exposed to damaging transients
between the lines and earth. Any surge
current appearing as a series-mode or
common-mode transient is converted into a
common-mode voltage whereupon the
transmitter electronics are temporarily
raised to some higher voltage level before
‘floating’ down automatically (and without
damage) to resume normal operation.
The TP32 protection network is a hybrid
design
consisting of high-power, solid state
electronics and a gas discharge tube which
are capable of diverting surges up to 10kA.
Encased in an ANSI 16 stainless steel
enclosure, the TP32 exhibits unparalleled
mechanical durability providing years of
maintenance free operation in harsh
environments. The enclosure is available
threaded for all the common conduit entries.
Versions are available for

Installation is very simple and can easily be
carried out retrospectively to existing
installations. The TP32 is screwed into any
unused conduit entry on the transmitter case
allowing flying leads to connect the device to
the terminal block (+ve, -ve) and the internal
earth stud within the transmitter housing. By
connecting in parallel to the transmitter
circuit the TP32 does not
interfere with the normal
operation of the bus –
passing ac or dc
signals without adding increased voltage
drop across the segment while consistently
diverting surge currents safely to earth and
clamping output voltages to safe levels.
For hazardous area use, approvals for both
intrinsically safe and flameproof/explosionproof
operation are available, in all gas groups and
apparatus temperature classification up to
T6. CSA and FM approval is also available.
The TP32 is designed to meet the
requirements of IEC 61158-2:2000 and
ANSI/ISA-50.02-2 1992 for 31.25kB/sec
systems as used by FOUNDATION
Fieldbus, PROFIBUS-PA and
WorldFIP.
