Introduction

This users’ manual for Moore Industries’ IPH2 and
IPX2 Current-to-Pressure Transmitters contains all
of the information that is needed to calibrate, install,
operate, maintain, and troubleshoot this family of
transmitters.

The following guidelines are used in this manual:

WARNING - Hazardous procedure or condition that
could injure the operator.

Caution - Hazardous procedure or condition that could
damage or destroy the unit.

Note - Information that is helpful for a procedure,
condition, or operation of the unit.

About this Manual

Wherever you see a “WARNING”, “Caution”
or “Note” pay particular attention.

WARNING - Hazardous procedure or condition that
could injure the operator.

Caution - Hazardous procedure or condition that could
damage or destroy the unit.

Note - Information that is helpful for a procedure,
condition, or operation of the unit.

IPH2 & IPX

The rugged IPH2 and IPX2 Current-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 IPH2 and 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,
IPH2 and 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.
