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.

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.
