Description
The IPH is Moore Industries’ rugged and compact
Field-Mount Current-to-Pressure (I/P) Transmitter. It is
designed to meet NEMA 4X and IP55 requirements, is
watertight, dust-tight, and resistant to corrosion and
chemicals. These qualities make the IPH the ideal
transmitter for extended use in harsh situations.

The 2-wire (loop-powered) IPH accepts a 4-20mA input
from a DCS, PLC or PC-based control system. It
converts the current signal to a pneumatic signal
(3-15psig, 0.2-1 Bar, 20-100 kPa, etc.), providing
precise proportional control of valves, actuators, and
other pneumatically-controlled devices. Reverse
pneumatic outputs (15-3psig, 1-0.2 Bar, 100-20 kPa,
etc.) are also available.
The IPH is available with an optional coalescing
filter/regulator that combines an air filter, a miniature
supply line regulator, and a pressure gauge that reads
in both psi (0-60) and Bars (0-4).
Model/Serial Number. Moore Industries tracks all
their IPH units with a system of model numbers and
serial numbers. Please be prepared to provide these
numbers if you need service information or assistance.
The IPH serial and model numbers can be found on
the instrument’s metal tag.

Calibration
Every IPH is fully tested and calibrated at the factory
prior to shipment. Before installation, however, your
IPH’s should be bench-checked to verify proper
operating levels and to set 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
IPH. This equipment is not supplied by Moore
Industries, but should be available in most labs or
maintenance areas.

Preparing for Calibration
To prepare the IPH for calibration, remove the
screw-on cap and connect the unit to your calibration
equipment as shown in Figure 1 on page 3, which
shows the calibration setup.
Unit Connections and Controls. The IPH has two
labeled terminals on its faceplate, located under the top
protective cover of the housing. The terminal labeled
“+I” is for connection of the positive current input, and
the terminal labeled “–I” is for negative connections.

IPH
The two IPH controls are also located inside the unit
housing under the screw-on cap. They consist of a
mechanical adjustment screw and an electronic
potentiometer, each accessed through the front panel.
They are labeled “zero” and “span”. The zero adjustment screw mechanically provides a control range for
zero offsets of ±3 percent of rated unit span.
The span pot electronically adjusts unit full-scale
output to 100 percent of rated span. It requires approximately 22 turns to move its wiper from one
extreme to the other, clockwise for maximum or
counterclockwise for minimum span. It 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 IPH.
All pneumatic lines used in calibration and operation
must be “blown down” (purged) prior to connection to
the IPH. Any condensation or oil residue in the lines, if
introduced into the pneumatic chambers of the IPH,
may result in poor unit performance.
Calibration Steps:
(See Figure 1)
1. Orient IPH vertically or horizontally based on
how it will be positioned in the application.
2. With zero air input (supply off), connect 1/4-inch
pneumatic tubing between the appropriate output
port of the regulated instrument air supply and the
calibrated pressure gauge #1 (accuracy of ±2% of
span). Connect another hose from the pressure
gauge to the port labeled “IN” on IPH.
3. Connect 1/4-inch pneumatic tubing between the
IPH 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.
4. Run current source wiring through conduit opening
in housing, and to front panel of IPH.
5. Connect positive lead of adjustable current source
to +I terminal of IPH. Connect negative source
lead to –I IPH terminal. A dc multimeter may also
be connected to verify level of current input.

7. Apply appropriate filtered, instrument-quality air to
supply line: 20 or 35 psi (40 kPa, or 1.4 bar).
Verify appropriate supply pressure by checking
Supply Pressure field of unit model number.
8. Set span pot to approximately mid-scale (22 turns
in either direction, then approximately 11 turns in
the opposite direction).
9. Set zero adjustment screw fully clockwise, then
five turns counterclockwise.
10. Allow approximately 30 seconds for calibration
setup to stabilize.
Calibration Process
To perform the recommended bench-check for the
IPH, first perform the setup as described in the preceding section. The calibration procedure consists of a
basic check and adjustment of unit zero and span,
based on the reading of pressure gauge #2 (accuracy
of ±0.1%).
Table 2 lists the values to be used during calibration.
Refer to the table when performing the following:
1. Check unit zero setting. Monitor reading of
pressure gauge #2 (output), and turn zero adjust
screw counterclockwise to lower output, clockwise
to raise output. Set zero adjust screw so that
pressure output is at 0% of appropriate range
(±3%) when 0% input is applied.
2. Check unit span setting. Increase input to 100% of
rated span (20 mA).
3. Monitor reading of pressure gauge #2 (output), and
adjust span pot so that reading is at 100% of
appropriate pressure range for your unit.
Check the values listed in Table 2.
4. Repeat steps 1 through 3 until IPH outputs 0% of
rated pressure range at 0% current input, and
100% of output pressure range at 100% current
input.
5. Verify the accuracy of your adjustments by inputting the appropriate percent of span levels listed in
table 2.
For NEMA4X and IP55 Installations, the unit must be mounted
vertically or within 45 degrees of vertical.
The Interface Solution Experts5
IPH
Installation
The installation of the IPH is carried out in three
phases. The first phase is the physical mounting of the
unit. Next is the electrical connections phase, and
finally, pneumatic connections can be made. It is
strongly recommended that IPH’s be installed in this
order. It is also strongly suggested that each unit be
calibrated according to the instructions in this manual
before being placed into service.
The IPH may be installed at any angle: either surfacemounted or attached to pipe or round conduit. When
deciding on the placement of the IPH unit, make sure
to consider the possibility of needing to: access the
front panel, check the fittings, read the -FR1 Option
gauge, or drain the filter.
Closed Loop/Open Loop. The IPH should be
installed in a closed loop. A closed loop is the best
way to measure a control variable. It also helps
determine if a deviation from a desired value exists and
provides feedback for actuator loading pressure.
An open loop has limitations that are not consistent
with precise control. Long term drift of the loop dynamics, load fluctuations that require constant adjustments
of the actuator loading pressure, and performance
quality variations due to inconsistencies between
operating personnel are all problems commonly
associated with open loops. A controlled variable
cannot be directly measured in an open loop; this
prevents compensating adjustments to the system
input.
Phase Two: Electrical Connections
To complete the electrical connections, route the wiring
through the conduit port to the terminal block, then use
a slotted-tip screwdriver with a maximum head width of
3 mm (0.125 inch) to loosen the terminal screws.
The terminals are comprised of compression-screw
sockets that accommodate 22-14 AWG wiring.
Connect positive lead (+) to terminal labeled “+
negative lead (–) to terminal labeled “–I”. Tighten the
terminal screws until snug.
Use shielded, twisted-pair wiring for low-level input.
Ground the shielding wire as close as possible to the
installed IPH.
I”, and
Phase Three: Pneumatic Connections
To complete the final phase of installation, the pneumatic connections, connect the supply line to the
1/4-inch NPT female port labeled “IN”. Connect the
output line to the 1/4-inch NPT female port labeled
“OUT”.
Seal all fittings with Teflon® tape, or equivalent. Always
“blow down” (purge) all tubing and the controlled
device before connecting the IPH.
Filters. The IPH requires filtered, dry, regulated,
instrument-quality air to prevent clogging and to ensure
extended periods of maintenance-free operation.
Moore Industries suggests the following levels of
filtering protection:
Phase One: Mounting
Figure 2 gives the IPH’s outline dimensions. The
illustration also gives the dimensions of the available
-FR1 Option hardware, which is recommended for
most installations.
After placing the IPH in the desired location and
orientation, secure the housing with the optional pipe
mounting hardware or other appropriate fasteners.
If you have further questions on how to mount the IPH,
contact your Moore Industries Sales Representative for
assistance.
NOTE:
For NEMA4X and IP55 Installations, the unit must be
mounted vertically or within 45 degrees of vertical.
6The Interface Solution Experts
•Pre-filter – A general purpose “rough” filter, used
to reduce particulate matter to 5 microns in size.
Also removes bulk liquids. Although not required,
this filter is especially recommended to protect the
0.01 micron final filter when used.
•Final Filter – A second, final filter is recommended, to remove particulate matter in sizes
down to 0.01 micron. This filter removes virtually
all condensable liquids from the air stream as well.
•Filter/Regulator Module Option – A combined
filter/regulator assembly, the -FR1 Option, offered
as an accessory for the IPH, removes particles
down to 0.01 micron, supplying regulated, instrument-quality air to the unit. This space-saving
module is affixed to the IPH supply port, and
comes with a pressure gauge scaled in both psi
(0-60) and bars (0-4).
IPH
Operation
Once the IPH unit’s calibration has been checked or
adjusted and the unit has been installed properly, the
IPH operates unattended with the exception of the
minor maintenence procedures that are described in
the next section.
Remember that if an IPH is installed in an open loop, it
may appear to drift over extended periods of time
because of the lack of corrective feedback.
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 flows through the IPH during 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 maintenance interval geared to the user’s air
supply cleanliness. Refer to the next section for
instruction on the disassembly and cleaning of the IPH.
this equipment is not available, your facility may not be
qualified to perform the operations described in this
section. Contact Moore Industries’ Customer Service
Department for more information.
Disassembling the IPH
To disassemble the IPH for maintenance/cleaning,
unscrew the protective top cover, then unscrew the two
screws from the base and remove the unit.
Take the internal assembly out of the housing by
pulling straight out, away from housing base. Apply
steady pull, disengaging the pneumatic fittings from
their ports in the housing base. Do not disassemble
the pneumatic block at this time.
Separate the faceplate from the transducer by removing the screws on both sides of the plate assembly.
Cleaning the Subassembly
1. Place subassembly on work surface with zero
screw and span pot down.
2. Use syringe to fill Orifice #1 with trichloroethane
(TCE). See Figure 3.
Maintenance
Before beginning IPH maintenance, the unit must be
removed from its application.
Warning: It is strongly recommended that the
maintenance procedures be performed in a clean,
controlled environment, such as a technicians’
bench, a laboratory, etc. Several internal parts are
small and precision-machined and can be easily lost
or damaged if an attempt is made to perform
maintenance in the field.
After maintenance, each IPH should be recalibrated
before it is returned to service. Refer to the Calibration
Section of this manual for instructions.
Necessary Equipment
To perform the basic maintenance procedure for the
IPH, refer to Table 3, which lists the required
equipment. These materials are not supplied by Moore
Industries, but should be available in maintenance
areas prepared to perform this type of procedure. If

Re-assembly
1. Dry all parts of the pneumatic block and the
mechanical subassembly with the specified air or
nitrogen supply. Make sure all parts are clean and
dry.
2. Use the scratch markings made earlier to make
sure that each section of pneumatic block is
oriented properly, then use small socket-head
screws to secure re-assembled block. Tighten
screws to between 35 and 45 Nm of torque (26 to
33 ft/lbs).
3. Line up pin on section #1 of pneumatic block with
hole on base plate of mechanical subassembly.
4. Place a small amount of thread-locker on the
threads of the head screw used to hold the pneumatic block and mechanical subassembly together,
and secure two subassemblies to each other with
the screw. Make sure screw is as tight as possible.
Drain Check. System filters have automatic drains
that depend on the fluctuation of system pressure to
induce drainage. A stable system may not drain
efficiently.
Check periodically for clogs and drain system’s filters
by pushing the drainage valve with a small probe or
wire.
Troubleshooting the IPH
Many components of the IPH have been thermally
aged, tested, and selected using a computer-aided
design program. This usually makes field repair
unnecessary.
It is therefore recommended that any properly maintained unit found to be performing below specifications
be returned to the factory in accordance with the
instructions found on the back cover of this manual.
If a problem is suspected with the IPH, review the
following steps:
1. Verify that bench instruments used to take measurements have the proper range and accuracy
and are within current certification period limits.
2. If a change in the relationship between the input
and output is detected, attempt a re-calibration of
the IPH.
3. If the response time lengthens, or if the span
drops, this may indicate a blockage due to air
supply contamination. Follow the instructions in
the Maintenance Section of this manual.
5. Place mounting bracket over subassembly and
pneumatic block and screw the bracket onto the
subassembly.
6. Slide internal assembly into housing, being careful
not to crimp or pinch the current wiring, and mate
fittings in housing with ports on pneumatic block of
internal assembly. Press down until locked into
place.
7. Reseat the IPH and screw it in.
8. Calibrate unit. Refer to Calibration Section of this
manual for detailed instructions.
10The Interface Solution Experts
The Zero Adjust Screw. This screw has a flange to
prevent its being turned too far counterclockwise
during adjustment. Forcing the screw past the point at
which its flange comes into contact with the unit front
panel could disengage it from the internal assembly.
If this happens, disassemble the IPH as described in
the Maintenance Section of this manual.
Visually inspect the screw, and if serviceable, hold
down the flapper arm and turn the screw clockwise
until its pin is in a position to hold the arm.
Refer to the Calibration Section of this manual, and
recalibrate unit.

GUIDELINES AND CERTIFICATIONS
Low Voltage Directive
When installing any Moore Industries product, always follow all local regulations and standards for
grounding, shielding, and safety. The following
grounding and wiring practices must be followed in
order for the unit(s) to meet the requirements set
fourth in the EMC directives EN50082-2 and
EN55011.
Grounding
If the unit has a metal case it is to be grounded.
(DIN rail mounted units should be mounted on a
grounded rail).
Wiring
Twisted shielded wire should be used for all input
and output signals. The shields are to be grounded
at the units, to earth ground (safety ground). The
un-shielded part of the in/output wires should be no
longer than 2 inches.
CE Certification-related Guidelines
The following guidelines must be followed in order
to comply with EN61010-1 (Low Voltage Directive).
These items affect the AC version of the IPH. If
these products are to be used in a non-CE environment, this directive may be disregarded.
WARNING:
If this unit is used in a manner not specified by
Moore Industries, the protection provided by the
equipment may be impaired.
Switches and Circuit Breakers
A switch or circuit breaker must be wired in series
with the AC power conductors. The switch or circuit breaker used must be located within three
meters of the unit.
WARNING:
Terminals on this unit may be connected to
hazardous voltages. Before making ANY
connections to this unit, ALL hazardous voltages
must be de-energized.
The circuit breaker or switch will only remove
power to the unit, hazardous voltages may still be
connected to other terminals on the unit.
Installation Category
All of Moore Industries’ terminals are rated CAT II,
except those with the -RF option. These terminals
are rated CAT I.
Equipment Ratings
The IPH does not generate hazardous voltages,
rather, it accommodates a current input, and generates a pressure output. Products connected to
the IPH should be designed to receive these inputs.
Supply Wiring
All power connections should be made with the
proper wire.
The end of each conductor should be stripped no
more than 8mm. The end of the stripped wire
should be tinned with solder, or inserted into a ferrule and crimped before being placed into a terminal block.
Conductors connected to screw-type connections
should have a ring-lug or spade-lug crimped onto
the wire end.
