IPH2& IPX2
The rugged IPH2and IPX2Current-to-Pressure (I/P)
Transmitters are designed specically for extended
duty in harsh eld environments. Being Type
3X/4X- and IP56/IP66-rated, the extruded aluminum
housings, for both the IPH2and IPX2, o󰀨er water
and dust protection and are also highly resistant to
corrosion and chemicals. In addition, while the air and
natural gas versions of the IPX2 are explosion-proof,
the later o󰀨ers an increased ingress protection of IP66.
These 2-wire (loop-powered) transmitters convert
a current signal to a pneumatic signal so that an
electronic-based system such as a DCS, PLC, or PC
can control a pneumatic actuator, valve, or damper
drive. Available models accept a wide range of current
inputs (4-20mA, 4-12mA, and 12-20mA) and provide a
proportional pneumatic signal (3-15psig, 0.2-1Bar,
20-100kPA, etc.). A reverse pneumatic output option
is available for the IPH2. Reverse output is switch
selectable on new versions of the IPX2(introduced in
2013).
The high-performance line of I/P transmitters
utilizes an internal feedback loop to ensure accurate
operation. The feedback loop consists of an internal
pressure transducer that samples the unit’s output
pressure and compares it to the input signal. This
allows the unit’s output to track the input signal. Other
I/P transmitters, such as our original IPT, IPH and IPX
models, rely solely on mechanical positioning.
Since the feedback loop requires power to operate,
when there is no input power to the unit, the pneumatic
output will be shut o󰀨. Units that use mechanical
positioning only, will typically still have a pneumatic
output when power is removed. By example, a unit
(IPT, IPH and IPX) with an output range of 15 - 3PSIG
will output approximately 18PSIG when the input
signal is removed. This is not an issue except for
those users that rely on this elevated output (18PSIG)
to maintain a valve’s position upon the unexpected
loss of input signal (4-20mA). In such cases, the IPT2,
IPH2and IPX2 units react di󰀨erently by shutting o󰀨 the
pneumatic output.
Both units are available with an optional coalescing
lter/regulator that combines an air lter and miniature
supply line regulator with a pressure gauge that reads
in both psi and Bars.

Calibration
Every IPH2and IPX2 is fully tested and calibrated at the
factory prior to shipment. However, before installation,
your IPH2or IPX2 should be bench-checked to verify
the desired unit zero and unit span. Calibration should
be conducted in an appropriate testing environment.
Necessary Equipment
Table 1 lists the equipment required to calibrate
the unit. This equipment is not supplied by Moore
Industries, but should be available in most labs or
maintenance areas.
Preparing for Calibration
To prepare the IPH2or IPX2 for calibration, remove
the screw-on cap and connect the unit to your
conguration equipment as shown in Figures 3 and 4.
Unit Connections and Controls. The IPH2and IPX2
each have two labeled terminals on their faceplate,
located under the top protective cover of the housing.
The terminal labeled “+PS” is for connection of the
positive current input, and the terminal labeled “–PS”
is for the negative connection.
The two controls are also located inside the unit
housing under the screw-on cap. They consist of
two potentiometers, each accessed through the front
panel. They are labeled “zero” and “span”. The zero
potentiometer provides a control range for o󰀨sets of
±10% of rated unit span, while the span potentiometer
adjusts unit full-scale output to 100 percent of rated
span.
Each potentiometer requires approximately 20 turns
to move its wiper from one extreme to the other:
clockwise for maximum, or counterclockwise for
minimum values. Each is equipped with a slip clutch
to prevent damage if the adjustment is turned beyond
the wiper stop.
Note:
Always use clean, dry, instrument air when
calibrating or operating the IPH2or IPX 2.
All pneumatic lines used in calibration and operation
must be “blown down” (purged) prior to connection to
the unit. Any condensation or oil residue in the lines,
if introduced into the pneumatic chambers of the unit,
may result in poor unit performance.
Calibration Process
To perform the recommended bench-check for the
IPH2or IPX2, rst perform the setup as described in
the next section. See Figures 3 and 4 for illustrations
of the Calibration Setup, then follow the steps under
Calibration Setup and Calibrating the IPH2or IPX2.
Calibration Setup
1. Connect 1/4-inch pneumatic tubing between the
appropriate output port of the regulated instrument
air supply and the pressure gauge #1 (accuracy
of ±2% of span). Connect another tube from the
pressure gauge to the port labeled “IN” on IPH2or
IPX2.
2. Connect 1/4-inch pneumatic tubing between the
port labeled “OUT” and the appropriate port of
pressure gauge #2 (accuracy of ±0.1% of span),
then from gauge #2 to the appropriate pneumatic
load.
3. Run current source wiring through conduit opening
in housing, and to the front panel of the IPH2or
IPX2. (Not necessary for IPX2–NG models.)
4. Connect positive lead of adjustable current source
to the +PS terminal of unit. Connect negative
source lead to the –PS terminal. (For IPX2–NG,
connect the positive lead of the current source
to the red wire, and the negative lead of current
source to the black wire.) A multimeter may also
be connected to verify level of current input.
5. When connections are complete, apply an input
current of 0% of span. (i.e. 4mA for a 4-20mA unit)
6. Apply appropriate ltered, instrument-quality air to
supply line: 20 or 35psi (1.4Bar to 2.4Bar). Verify
appropriate supply pressure by checking Supply
Pressure eld of unit model number.
7. Allow approximately 30 seconds for calibration
setup to stabilize.

Calibrating the IPH2or IPX2
This calibration procedure consists of a basic check
and adjustment of unit zero and span, based on the
reading of pressure gauge #2. To calibrate a direct
output unit, perform the following:
1. For IPX2new versions (introduced in 2013) only,
check switch is set to “Direct”- see Figure 5.
2. Check unit zero setting. Monitor reading of
pressure gauge #2 (output), and turn zero
potentiometer counterclockwise to lower output,
clockwise to raise output. Set zero potentiometer
so that pressure output is at 0% of span when a
current input of 0% of span is applied. (i.e. 3psi for
a 3-15psi unit)
3. Check unit span setting. Increase input to 100%
of rated span (i.e. 20mA for a 4-20mA unit).
4. Monitor reading of pressure gauge #2 (output),
and adjust span potentiometer so that reading is at
100% of span for your unit (i.e. 15psi for a 3-15psi
unit).
5. Repeat steps 1 through 4 until the unit outputs 0%
of rated pressure range at 0% current input, and
100% of output pressure range at 100% of span.
6. Verify the accuracy of your adjustments by
inputting 0%, 25%, 50%, and 75% of span inputs,
and monitoring the output.
To calibrate a reverse output unit, perform the
following:
7. For IPX2new versions (introduced in 2013) only,
check switch is set to “Reverse” - see Figure 5.
8. Check unit zero setting. Monitor reading of
pressure gauge #2 (output), and turn zero
potentiometer counterclockwise to lower output,
clockwise to raise output. Set zero potentiometer
so that pressure output is at 100% of span when a
current input of 0% of span is applied. (i.e. 15 psi
for a 3-15 psi unit).
9. Check unit span setting. Increase input to 100%
of rated span (i.e. 20mA for a 4-20mA unit).
10. Monitor reading of pressure gauge #2 (output),
and adjust span potentiometer so that reading is
at 0% of span for your unit (i.e. 3 psi for a 3-15 psi
unit).
11. Repeat steps 8 through 10 until the unit outputs
100% of rated pressure range at 0% current input,
and 0% of output pressure range at 100% of span.
12. Verify the accuracy of your adjustments by
inputting 0%, 25%, 50%, and 75% of span inputs,
and monitoring the output.
Note:
New versions of the IPX2(introduced in 2013) have
a selectable output switch. Be sure to set this switch
to the required output mode, direct or reverse, and
use the corresponding set of pots accordingly.

Current-to-Pressure
(I/P) Transmitters
Installation
The installation of the IPH2or IPX2 is carried out in
three phases: the physical mounting of the unit, the
electrical connections phase, and the pneumatic
connections phase. It is strongly suggested that each
unit be calibrated according to the instructions in this
manual before being placed into service.
Installation in hazardous ‘Classied’ locations and
potentially explosive atmospheres must adhere to the
instructions in the Hazardous Location Applications
section which can be found at the end of this
Installation section.
Phase One: Mounting
Figures 1 and 2 give the dimensions of the IPX2and
IPH2, respectively. The illustrations also give the
dimensions of the available option hardware, which is
recommended for most installations. After placing the
unit in the desired location and orientation, secure the
housing with the optional pipe mounting hardware or
other appropriate fasteners.
The IPH2or IPX2will operate when installed at any
angle–either surface-mounted or attached to pipe or
round conduit. However, there are other considerations
in selecting the ideal mounting position. If the IPH2is
in an area which may be exposed to rain or water, it
should be mounted within 45° of vertical. In natural
gas applications, where liquid remnants are possible
in the supply, the vent port of the IPX2needs to be
in a position that would allow for su󰀩cient draining.
Please also consider the requirements in Pneumatics
Connections on the next page before determining the
ideal mounting conguration.
Phase Two: Electrical Connections
To complete the electrical connections, route the wiring
through the conduit port to the terminal block, then
use a screwdriver to loosen the terminal screws. (Not
necessary for IPX2–NG1 or –NG2 installation.)
For all units except the IPX2–NG1 or –NG2, connect
positive lead (+) to the +PS terminal, and negative
lead (–) to the –PS terminal. Tighten the terminal
screws until snug.
Caution:
When connecting the IPX2Natural Gas (–NG1 or
–NG2) model, use an appropriately certied conduit
box and wire connectors. Do not attempt to remove
the seal tting, as it is necessary for natural gas
certication. Connect the positive lead (+) to the red
wire from the seal tting, and the negative lead (–) to
the black wire from the seal tting.
Use shielded, twisted-pair wiring for low-level input.
Ground the shielding wire as close as possible to the
installed unit.
Recommended Ground Wiring
Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal case
or housing should be grounded.
• The protective earth conductor must be
connected to a system safety earth ground
before making other connections.
• All input signals to, and output signals
from, Moore Industries’ products should be
wired using a shielded, twisted pair wiring
technique. Shields should be connected to an
earth or safety ground.
• For the best shielding, the shield should be
run all the way from the signal source to the
receiving device. (see Note below)
• The maximum length of unshielded input and
output signal wiring should be 2 inches.
Note:
Some of Moore Industries’ instruments can be
classied as receivers (IPT2, IPX2, etc.) and some
can be classied as transmitters (TRX, TRY, etc.)
while some are both a receiver and a transmitter
(SPA2, HIM, etc). Hence, your shield ground
connections should be appropriate for the type
of signal line being shielded. The shield should
be grounded at the receiver and not at the signal
source.
CE Conformity
Installation of any Moore Industries’ products that carry
the CE marking must adhere to the guidelines in the
Recommended Ground Wiring Practices section in
order to meet the EN 61326 requirements set forth in
the applicable EMC directive.

Demand Moore Reliability 11
IPH
2 &IPX 2
Current-to-Pressure
(I/P) Transmitters
Phase Three:
Pneumatic Connections
To complete the nal phase of installation, connect the
supply line to the ¼-inch NPT female port labeled “IN”.
Connect the output line to the ¼-inch NPT female port
labeled “OUT”. All tubing must have at least 6mm
(¼-inch) inside diameter or the maximum ow will be
limited.
Note:
Seal all ttings with Teon®tape, or equivalent.
Always “blow down” (purge) all tubing and the
controlled device before connecting the IPH2or IPX2.
Manual Override Screw
If you are in a potentially explosive environment and
do not want to apply electric power to the unit with
the cover removed, the pneumatic installation may
be tested by loosening the manual override screw on
the bottom of the unit. The output pressure will go to
the supply pressure. Be sure to tighten the manual
override screw after test.
WARNING:
IPX2units installed in a natural gas application must
have the natural gas vent properly connected. Follow
the directions below to install an IPX2with –NG1 or
–NG2 options into a natural gas application.
Natural Gas Applications
Customers using the IPX2with –NG1 or –NG2 options
to regulate a sweet natural gas application (H2S levels
are not to exceed 20ppm) must also make the vent
port connections. Connect the Natural Gas Vent
(shown in Figure 1) to a device prepared to receive
natural gas. After connection, the ttings, cover, and
lter/test screw should be tested for leaks.
For an outdoor system, ventilation should consist of a
weather-proofed connection between the transmitter
exhaust and a riser, six feet above the transmitter
and control valve assembly. The riser should be
shepherd-crooked to prevent rain or incident water
from accumulating at the base. In accordance with
local safety regulation, an in-line ame arrestor should
be applied to the riser to prevent ash back to the
transmitter from an external, spontaneous ame
source.
For an indoor system, ventilation must consist of
a leak-proof connection from the exhaust of the
transmitter to a process vent. The process vent
should already be dedicated for natural gas excursions
and should conform to all standards for aring or
after-burn, and ame arrest, as dictated by local
environmental and safety regulations.
Indoor natural gas operations are typically monitored
to maintain safety conformance outside the lower
and upper explosion limits (LEL and UEL). To add
a natural gas operated transmitter in these cases,
consideration should be made as to the extent of
natural gas leak detection legacy to the installed
transmitter. Placement of the transmitter should be
such that detection and alarming surround any critical
connections between the transmitter and the natural
gas process.
If the natural gas driven transmitter is to be installed
indoors with no legacy monitoring capabilities,
additional consideration must be made to ensure the
operating area is well-ventilated and the transmitter
can be exhausted to process vent. Furthermore,
monitoring with remote annunciation within LEL and
UEL should be projected as an upgrade to the facility,
concurrently with this installation. The transmitter
installation must adhere to local environmental and
safety regulations.
WARNING:
IPX2units installed in a natural gas application must
have the natural gas vent properly connected. Failure
to do so may result in an explosion. The –FR1 option
should not be used with a ammable gas because it
has a vent to atmosphere. A lter-regulator without a
vent may be used. For natural gas certication to be
valid, the vent system must be able to maintain <1psig.
Filters. The IPH2 and IPX2 requires ltered, dry,
regulated, instrument-quality air to prevent clogging
and to ensure extended periods of maintenance-free
operation. Moore Industries suggests the following
levels of ltering protection:
• Pre-lter – A general purpose “rough” lter, used
to reduce particulate matter to 5 microns in size.
Also removes bulk liquids. Although not required,
this lter is especially recommended to protect the
0.01 micron nal lter when used.
• Final Filter – A second, nal lter is recommended
to remove particulate matter in sizes down to
0.01 micron. This lter removes virtually all
condensable liquids from the air stream as well.
• Filter/Regulator Module Option – A combined
lter/regulator assembly, the -FR1 Option, o󰀨ered
as an accessory for either the IPH2or IPX2,
removes particles down to 0.01 microns, supplying
regulated, instrument-quality air to the unit. This
space-saving module is a󰀩xed to the supply port,
and comes with a pressure gauge scaled in both
psi (0-60) and Bars (0-4).

Operation
Once the unit has been congured and installed, it
operates unattended with the exception of the minor
maintenance procedures that are described in the next
section.
If the unit is determined to be the cause of a loop
irregularity, carry out the maintenance procedure in the
next section of this manual. If problems persist, refer
to the Troubleshooting Section.
Instrument-quality Air. Air from the application
continuously ows through the IPH2/IPX2during
operation. Depending upon the purity of the air
supply, the unit’s internal assembly may have to be
removed and cleaned to ensure continued optimum
performance.
Initially, random checks can help establish a
satisfactory internal maintenance geared to the user’s
air supply cleanliness. Refer to the next section for
instruction on the disassembly and cleaning of your
unit.
Maintenance
For most applications, no maintenance outside of
routine inspection and calibration of the IPH2or IPX2
will be necessary. These units are designed to work
unattended for up to six months with little change in
accuracy.

the recovery of the unit, by allowing any accumulated
liquid to drain out more e󰀨ectively. To remove the
module follow these steps:
1. Use a 3mm Allen wrench to unlock the cover.
Drive the Allen screws clockwise until the cover
is allowed to rotate freely. Remove the cover by
accessing the locking screw shown in Figure 6.
2. Use a Phillips head screw driver to remove the
four module mounting screws shown in Figure 7.
3. Carefully, pull the module from the housing. The
pneumatic stem, found on the bottom of the
module, is fragile; handle with care. See Figure 8.

Troubleshooting
the IPH2& IPX2
If a problem is suspected with the IPH2or IPX2, review
the following steps:
1. Verify that bench instruments used to take
measurements have the proper range and
accuracy and are within current certication period
limits.
2. If a change in the relationship between the input
and output is detected, attempt a re-calibration of
the unit.
3. If the response time lengthens, or if the span
drops, check the system for a blockage due
to air supply contamination. Please refer to
Maintenance section for details of replacing lters,
electronic modules and drain checking.
If the unit needs to be returned for service, the
complete valve assembly can be removed from
the housing for replacement without disturbing the
connections to the housing. Contact customer service
for details.
Drain Check
System lters (not IPX2/IPH2 lters) have automatic
drains that depend on the uctuation of system
pressure to induce drainage. A stable system may not
drain e󰀩ciently. Check periodically for clogs and drain
system’s lters by pushing the drainage valve with a
small probe or wire.
IPX2Replacement Modules*
*This applies only to new versions of the IPX2
introduced in 2013.
In abnormal operating conditions in which a slug
(liquid) is present in the IPX2air/ gas supply, the
electronic module may be removed. This can help in

4. Inspect the module and the barrier plate for any
signs of contamination. Remove any excess liquid
and allow to dry before replacing. The electronic
module is not eld-serviceable. If irreparable
damage is found, it may be replaced. See Data
Sheet for ordering information.
5. To re-assemble, replace the module using locating
pins (see step 3), tighten the 4 module screws
(see step 2), replace the cover and secure with the
locking screw (step 1).
6. Recalibrate the unit before returning to service.
Refer to the Calibration Section of this manual for
instructions.
