IPT-DIN
Current-to-Pressure Transmitter
January 2005
Description
The IPT-DIN Current-to-Pressure Transmitter accepts
a 4-20mA input signal and is capable of supplying a 315psig (or 15-3psig) pneumatic output signal, as well
as a number of other pneumatic signals typically used
in I/P-type process control applications. Available in a
compact, aluminum housing that is only 40mm wide,
the IPT unit can be conveniently snapped onto any
standard mounting rail or a Moore Industries pneumatic header rack for use in high-density control room
and factory installations. This versatile transmitter will
interface with just about any kind of process control
instrumentation including chart recorders, data
loggers, panel meters, multiplexers, controllers and
computers.
The IPT offers infinite resolution, output volume
up to 1.4SCFM, and air consumption as low as
0.1SCFM. Intrinsically safe units are available as an
option, and the transmitter itself can be enclosed in a
water-proof box. A front panel LED that varies in
intensity with the level of the pneumatic signal indicates input current, and complete RFI protection is
provided as a standard feature. To save time during
calibration and maintenance procedures, operation of
the IPT can be monitored using an optional pneumatic
test jack located on either the front or rear panel of the
unit. Within certain limitations, the customer may
select the location of the test jack, as well as the
locations of electrical input and pneumatic output
connections, by specifying the appropriate access
designation listed in Table 1.

The IPT-DIN pneumatic mounting block (left) allows the
unit to be easily snapped onto a DIN rail for high density
installation
Features
• Plug-in connections. Mounting block and optional
removable terminal block (-RTB) allow unit to be
taken out of service without use of tools.
• Vibration resistant. High-technology sensor is
insensitive to shock and vibration; unit may be
installed in any position.
• Self-sealing connection. Mounting block and
supply headers contain self-sealing valves which
offer quick release and no air loss.
• Accessory air filters available. Moore Industries
offers a series of air filters designed to protect the
IPT transmitter from plugging or corrosion.
