Description
The transducer, shown in figure 3, receives a 4 to 20
milliampere dc input signal and transmits a
proportional user field-configurable pneumatic output
pressure to a final control element. The pneumatic
output ranges are typically 0.2 to 1.0 bar (3 to 15
psig) and 0.4 to 2.0 bar (6 to 30 psig). A typical
application is in electronic control loops where the
final control element is a control valve assembly that
is pneumatically operated. The input signal and
output pressure range of the transducer is indicated
on the nameplate, attached to the housing.
CAUTION
Dropping or rough handling of the
transducer can cause damage to the
converter module resulting in a shifted
output or a minimum output.

Installation
The i2P-100 transducer has been designed and
approved for use with either air or natural gas as the
supply medium. In normal operation the unit will vent
the supply medium into the surrounding atmosphere
unless it is remotely vented. When using natural gas
as the supply medium in a non-hazardous location,
remote venting of the unit is required. Failure to do
so could result in personal injury, property damage,
and area re-classification. For hazardous locations
remote venting of the unit may be required,
depending upon the area classification, and as
specified by the requirements of local, regional, and
federal codes, rules and regulations. Failure to do so
when necessary could result in personal injury,
property damage, and area re-classification.
WARNING
To avoid personal injury or property
damage from the sudden release of
pressure:
DAlways wear protective clothing
and eyewear when performing any
installation operations.
DIf installing into an existing
application, also refer to the WARNING
at the beginning of the Maintenance
section of this instruction manual.
DCheck with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.

WARNING
This unit vents the supply medium into
the surrounding atmosphere. When
installing this unit in a non-hazardous
location with natural gas as the supply
medium, you must remotely vent this
unit to a safe location. Failure to do so
could result in personal injury or
property damage from fire or
explosion, and area re-classification.
When installing this unit in a
hazardous location remote venting of
the unit may be required, depending
upon the area classification, and as
specified by the requirements of local,
regional, and federal codes, rules and
regulations. Failure to do so when
necessary could result in personal
injury or property damage from fire or
explosion, and area re-classification.
Vent line piping should comply with
local and regional codes and should
be as short as possible with adequate
inside diameter and few bends to
reduce case pressure buildup.
Mounting
When a transducer is ordered as part of a control
valve assembly, the factory mounts the transducer
on the actuator and connects the necessary tubing,
then adjusts the transducer as specified on the
order. See figure 3 and 4 for typical mounting
configurations.
Transducers also can be ordered separately for
mounting on a control valve assembly already in
service, or for mounting on a 2-inch diameter
pipestand, or a flat surface. The transducer may be
ordered either with or without mounting parts.
Mounting parts include a mounting plate and bolts
and, if ordered for pipestand mounting, a pipe clamp.
Tubing is not included if the transducer is not factory
mounted. Use 0.375 inch diameter tubing for all
input and output connections. The length of tubing

Figure 6. Typical Type i2P-100 Mounting With Type 67CFR Filter Regulator
between the transducer output and the final control
element should be as short as possible. Transducer
overall dimensions are shown in figure 5. If
weatherproofing is required, mount the transducer
so that the vent can drain. Do not allow moisture or
condensate to collect in the vent.
Note
The vent will not drain properly when
mounted in the downward position.
Pneumatic Connections
As shown in figure 5, all pressure connections on the
transducer are 0.25 inch NPT female connections.
Use 0.375 inch tubing for all pressure connections.
Refer to the vent subsection below for remote vent
connections.
Supply Pressure Requirements
WARNING
Severe personal injury or property
damage could result from an unstable
process if the instrument supply
medium is not clean, dry, oil-free and
non-corrosive. While use and regular
maintenance of a filter that removes
particles larger than 40 microns in
diameter will suffice in most
applications, check with a Fisher Field
office and Industry Instrument air
quality standards for use with
corrosive air or if you are unsure about
the proper amount or method of air
filtration or filter maintenance.
Supply pressure must be clean, dry air or
noncorrosive gas. Use a Fisher Type 67CFR Filter
Regulator, or equivalent, to filter and regulate supply
air. The filter regulator can be mounted on a bracket
with the transducer as shown in figure 6 or mounted
on the actuator mounting boss. An output pressure
gauge may be installed on the regulator to indicate

To support diagnostic testing of
valve/actuator/positioner packages, special
connectors and hardware are available. Typical
connector installations are shown in figure 7. The
hardware used includes a 0.25 inch NPT pipe nipple
and pipe tee with a 0.125 inch NPT pipe bushing for
the connector. The connector consists of a 0.125
inch NPT body and body protector.
Note
If the Type i2P-100 transducer is used
in a valve assembly with a positioner,
no hook-up for diagnostic testing is
required for the Type i2P-100. The
hook-up for diagnostic testing should
be installed at the positioner.
Install the connectors and hardware between the
Type i2P-100 transducer and the actuator.
1. Before assembling the pipe nipple, pipe tee, pipe
bushings, actuator piping, and connector body, apply
sealant to all threads.
2. Turn the pipe tee to position the connector body
and body protector for easy access when doing
diagnostic testing.

Vent
WARNING
This unit vents the supply medium into
the surrounding atmosphere. When
installing this unit in a non-hazardous
location with natural gas as the supply
medium, you must remotely vent this
unit to a safe location. Failure to do so
could result in personal injury or
property damage from fire or
explosion, and area re-classification.
When installing this unit in a
hazardous location remote venting of
the unit may be required, depending
upon the area classification, and as
specified by the requirements of local,
regional, and federal codes, rules and
regulations. Failure to do so when
necessary could result in personal
injury or property damage from fire or
explosion, and area re-classification.
Vent line piping should comply with
local and regional codes and should
be as short as possible with adequate
inside diameter and few bends to
reduce case pressure buildup.
If a remote vent is required, the vent line must be as
short as possible with a minimum number of bends
and elbows. To connect a remote vent, remove the
plastic vent (key 71, figure 13). The vent connection
is 0.25 inch NPT female. Use 0.375 inch tubing to
provide a remote vent.

Equipment Required
Choose a current or voltage source that is capable,
without switching ranges, of driving the transducer
through its entire input range. Switching ranges on a
current or voltage source will produce spikes or
mid-scale reverses in the input signal presented to
the transducer, causing errors. The current source
should be capable of delivering 30 mA with 30 V dc
maximum compliance voltage.
Calibration Procedure
WARNING
To avoid personal injury or property
damage due to an uncontrolled
process provide some temporary
means of process control before
beginning the calibration procedure.
Refer to figure 10 for adjustment locations.
Note
The following steps are for a 4-20 mA,
0.2 to 1.0 bar (3 to 15 psig) configured
unit. The same procedure is used for
other configurations.
1. Remove electronics module cover (cover
adjacent to conduit entry, see figure 3 and 4).
2. Input and output ranges are selectable by dip
switch selection. Refer to figure 10 for dip switch
settings. Adjust dip switch settings and zero and
span as necessary to achieve the desired
input/output range.
3. If a current source other than the control device is
used as the input source, disconnect the control
device and connect the current source positive
terminal to the transducer ‘‘+’’ terminal and the
current source negative terminal to the transducer
‘‘-’’ terminal.
If an external meter is used, connect the current
source positive terminal to the transducer ‘‘+’’
terminal. Connect the meter positive terminal to the
transducer ‘‘-’’ terminal and the meter negative
terminal to the current source negative terminal as
shown in figure 8.
4. Check the supply pressure to ensure it is at the
recommended pressure. Refer to table 1, the
Specifications table, for supply pressure
recommendations.
5. Adjust the input current to the low milliamperes
dc.
6. The output pressure should be 0.2 bar (3 psig). If
not, adjust the ZERO potentiometer until the output
pressure is 0.2 bar (3 psig).
7. Adjust the input current to the high milliamperes
dc.
8. The output pressure should be 1.0 bar (15 psig).
If not, adjust the SPAN potentiometer until the output
pressure is 0.8 bar (15 psig).

pressure is within the referenced accuracy
requirements without further adjustment.
10. If a current source other than the control device
was used, disconnect the current source and
reconnect the control device.
Principle of Operation
The converter module receives a standard dc
current input signal from a control device to operate
coils in a force balanced beam system which in turn,
controls bleed air through an integral nozzle/flapper
arrangement. The nozzle pressure provides the
input signal to operate the relay as shown in figure
11. Relay output pressure is applied, through tubing,
directly to the final control element or valve/actuator
assembly.
Maintenance
The normal mode of operation for Type i2P-100
transducer requires that the pneumatic output
pressure be piped to the final control element. If this
is not done the resulting pneumatic output will vent
to the atmosphere.
Due to normal wear or damage from external
sources such as debris in the supply medium,
periodic maintenance or repair of the transducer
may be necessary. Maintenance of the transducer
consists of troubleshooting, removal for inspection,
and replacement of component parts, as well as
removal and inspection of the external removable
filter/restriction and cleaning or replacing as
necessary (see figure 1).
WARNING
To avoid personal injury or property
damage from the sudden release of
pressure:
DAlways wear protective clothing
and eyewear when performing any
maintenance operations.
DDisconnect any operating lines
providing air pressure, electric power,
or a control signal to the actuator. Be
sure the actuator cannot suddenly
open or close the valve.
DUse bypass valves or completely
shut off the process to isolate the
valve from process pressure. Relieve
process pressure on both sides of the
valve.
DUse lock-out procedures to be
sure that the above measures stay in
effect while you work on the
equipment.
DCheck with your process or safety
engineer for any additional measures
that must be taken to protect against
process media.
WARNING
For explosion-proof applications, or
when using natural gas as the supply
medium, disconnect power before
removing the housing cap. Personal
injury or property damage from fire or
explosion may result if power is not
disconnected before removing the cap.
CAUTION
When you replace components, use
only components specified by the
factory. Always use proper component
replacement techniques, as presented

in this manual. Improper techniques
can cause poor quality repairs and
impair the safety features of the
device.
The converter module and the
electronics module are non-repairable.
If troubleshooting or alignment
attempts indicate a faulty converter or
electronics module, replace the
module or return the transducer to
your Fisher sales office for repair.
Troubleshooting
Electrical
The following procedures require taking the control
valve/actuator assembly out of service. Provide
some temporary means of process control before
taking the control valve out of service.
1. Ensure terminal lug connections from the control
device to the transducer are of the correct polarity
(refer to the electrical connection procedures in the
Installation section of this manual).
2. At the transducer, ensure that the milliampere dc
signal is applied, and ensure that it is within the 4 to
20 milliampere range.
3. Check switches and ensure that they are properly
set. Refer to figure 10.
4. If the problem has not been resolved, see
Electronics Module Replacement in this manual.
Pneumatic
Provide a 4 to 30 milliampere dc current source,
supply pressure, and a gauge to monitor the output
pressure when checking transducer operation. Refer
to figure 13 for key number locations.
1. Ensure that supply pressure to the transducer
meets your requirements [0.3 bar (5 psi) higher than
upper range limit of output signal, with a maximum of
3.4 bar (50 psi)].
2. Ensure that the filter (key 11) and restrictor
(key 10) are open and clean. Remove the two
screws (key 14), the filter cap (key 13) and the
O-ring (key 12) to access the filter and restrictor.
3. If a filter/regulator is used, ensure that it is
working correctly. If not, ensure the dripwell is not
plugged because of excessive moisture
accumulation. If necessary, drain off any moisture,
and clean or replace the filter element.
4. Force the converter module to maximum output
pressure with a 30 milliampere dc signal. Output
pressure should build up to the approximate value of
the supply pressure [maximum of 3.4 bar (50 psi)].
5. When the input current is removed, the
transducer output pressure should drop to less than
0.14 bar (2 psig). If it does not, check to ensure the
vent and exhaust air passageway is free from
foreign material.
6. To inspect the relay assembly, refer to the Relay
Maintenance procedures in this manual.
7. If the problem has not been resolved, see
Converter Module Replacement in this manual.
Converter Module Replacement
Removal
Refer to figure 13 for key number locations.
1. Remove the housing cap (key 2) (the cap farthest
away from the conduit). Note that the two set screws
(key 8) need to be loosened to remove the cap.
2. Unscrew the two captive screws (key 52) and
remove the converter module from the housing.
3. Inspect the O-ring (key 55) and replace if
necessary.
Replacement
1. Lubricate the O-ring (key 55) with a lubricating
compound such as Dow Corning III before replacing
the converter module in the housing.
2. Insert the converter module into position in the
housing (key 1). Replace the two screws (key 52)
and tighten them.
3. Replace the housing cap (key 2), making sure to
re-tighten the two set screws (key 8).
4. Electrically calibrate the unit using the procedure
in the Calibration section of this manual.
Electronics Module Replacement
Removal
Refer to figure 13 for key number locations.
1. Remove the housing cap (key 2) (the cap closest
to the conduit). Note that the two set screws (key 8)
need to be loosened to remove the cap.
2. Note the location of the wires, then remove the
electrical wiring from the terminal block.

1. Insert the electronics module into position in the
housing (key 1). Replace the three screws (key 26)
and tighten them.
2. Replace the electrical wiring removed in step 1 of
the removal procedures. Do not overtighten the
terminal screws. Maximum torque is 0.45 NSm (4
lbfSin).
3. Electrically calibrate the unit using the procedure
in the Calibration section of this manual.
4. Replace the housing cap (key 2), making sure to
re-tighten the set screw (key 8).
Relay Maintenance
Refer to figures 12 and 14 for key number locations.
Removal
1. Remove the four mounting screws (key 36,
shown in figure 14) and remove the relay from the
transducer. Be careful not to lose the bias spring
(key 34) and input diaphragm (key 38).
2. Remove the body plug (key 32) that holds the
inner valve spring (key 35) and valve plug (key 39) in
place from the relay body assembly.
3. Remove the exhaust port assembly (key 33) from
the relay assembly.
4. Inspect the springs, exhaust seat, valve plug, and
other parts for wear or damage; replace as
necessary. Note: the valve plug supply seat is an
insert in the relay body (key 41). If this insert is bad,
replace the relay body.
5. Make sure all parts of the relay are clean and that
all passages are clear of foreign matter.
Assembly
1. Assemble the inner valve spring (key 35) onto the
body plug (key 32) and fit the valve plug (key 39)
onto the inner valve spring as shown in figure 12. To
assure best alignment between the valve plug, inner
valve spring, and body plug; fit the valve plug onto
the inner valve spring so that one of the three tabs at
the base of the valve plug sets at the end of the last
coil of the inner valve spring.
2. Lubricate the O-ring (key 42) with Dow Corning III
(key 37). Insert the assembled valve plug, inner
