The IPT
2
is a compact, closed-loop, 2-wire current-to-
pressure transmitter that converts a standard process
current signal to a pneumatic output. In its compact
aluminum housing, the IPT
2
snaps onto standard
mounting rails or onto a Moore Industries RIR or SIR.
Because of the low dynamic mass of the transducer
element, the unit can be mounted in any position and
is also insensitive to shock and vibration.
Individual IPT
2
s consist of two parts: the transmitter
section and an interlocking pneumatic mounting
Introduction
This is the users’ manual for Moore Industries’
advanced current-to-pressure transmitter, the IPT
2
. It
contains all of the information needed to confi gure,
install, operate, and maintain the IPT
2
.
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.
block, which snaps onto a rail. Units that are ordered
without a mounting block will clip onto an RIR or
SIR, which supplies air to each unit using only one
pneumatic supply pipe. Both mounting blocks
and supply headers contain self-sealing valves.
Therefore, the IPT
2
can be removed and replaced
without disturbing the pneumatic connections or
causing accidental venting of the supply or output air.
Operation can be monitored or calibration performed
by using the electrical input and optional pneumatic
output test jacks. A red LED display, which indicates
the presence of an electrical input signal, is also
standard.
Table 1 contains the IPT
2
equipment specifi cations,
including inputs, outputs, power requirements, and
performance characteristics.
Model Number. The IPT
2
model number describes
the equipment type, functional characteristics,
operating parameters, any options ordered, and unit
housing. If all other documentation is missing, this
number is used to identify equipment characteristics.
The model number for the IPT
2
is located on a label
on the side of the unit.
Serial Number. Moore Industries maintains a
complete history on every unit it sells and services.
This information is keyed to the serial number. When
service information is required on the IPT
2
, it is
necessary to provide the factory with this number.
The serial number is located on the side of the unit.
