Fisherr i2P-100 Electro-Pneumatic Transducer
The Fisher i2P-100 electro-pneumatic transducer, uses
a converter module that converts a milliampere input
to a proportional pressure output. Both the current
input and pressure output range are user-configurable
in the field. The converter module uses small parts of
minimum mass, which are balanced symmetrically
around a pivot point at the center of the mass. This
balanced arrangement results in a high performance
instrument that reduces sensitivity to vibration.
An integral pneumatic relay provides the high capacity
necessary to drive pneumatic control valve/actuator
assemblies without additional boosters or positioners.
The transducer also provides stable, accurate
operation when its output is transmitted to small
volume chambers, such as a pneumatic positioner or
other pneumatic instrument. Reduced sensitivity to
vibration, combined with high capacity and first order
lag characteristics, make the i2P-100 transducer
suitable for direct mounting on control valve/actuator
combinations.

n High Output Capability and Rangeability— The

integral output relay volume of the transducer is
adequate to drive valve/actuator combinations
without requiring a positioner or volume booster.
Selectable user field-configurable dip switch setting
for output range of 0.14 to 2.3 bar (2 to 33 psi).
n Split Range—Selectable user field-configurable

Features
n Approved for use with Natural Gas—The i2P-100 is

approved for use with natural gas as the pneumatic
supply.
n Low Pneumatic Supply Consumption—The

transducer has low pneumatic supply consumption
which lowers operating costs. Maximum steady
state consumption is less than the 6 SCFH
requirement set for the oil and gas industry by the
US Environmental Protection Agency (New Source
Performance Standards Subpart OOOO,
EPA­HQ­QAR­2010­0505).
n Single Sealed Device— The i2P-100 has been tested

in accordance with ANSI/ISA Standard 12.27.01
(Requirements for Process Sealing Between
Electrical Systems and Flammable or Combustible
Process Fluids) as a single sealed device.

two-way split range, using either half of the
standard input signal.
n Corrosion Resistant—Separate housing

compartments isolate the electronics from the
pneumatic process. The electronics module is
encased in a rugged plastic shell which helps to
prevent damage to the electronics. The printed
wiring board and dip switches are conformal coated
to help prevent corrosion. Converter module coils
have corrosion resistant coating and all flexures are
gold plated to provide protection from hostile
environments.
n Tolerant of Dirty Supply Medium—Free-flow pilot

stage design and large internal air passages provide
excellent tolerance to dirty pneumatic supply, by
reducing the effects of contaminant buildup and
erosion. The removable primary orifice and
replaceable 5 micrometer filter are easy to remove
for service and maintenance.
