1 Overview
ITP14 is a universally applicable process indicator and can be used with various current or
voltage standard signals. The device requires 24V DC auxiliary voltage. It is designed for
control and monitoring of industrial processes.
2 Specifications
ITP14 can be ordered in two versions. They
differ in the display color. Ordering key:

2.1 Galvanic isolation
The ITP14 has three potential groups:
− Power supply 24 V DC
− Analog input
− Digital output
Galvanic isolation from each group to enclosure 500 V
Galvanic isolation between groups 500 V
2.2 Environmental conditions
The device is designed for natural convection cooling. It should be taken into account when
choosing the installation site.
The following environment conditions must be observed:
− clean, dry and controlled environment, low dust level

Conditions Permissible range
3 Intended use
The device may only be used in the manner described in this user guide, properly installed
and in accordance with the specification. Damages caused by disregarding the instructions
of this manual are without liability. Non-observance of the safety guidelines may result in
damage to the device and injury to personal.
Improper use
Any other use is considered improper. Especially to note:
− The ITP14 may not be used for medical devices that sustain, monitor or otherwise affect
human life or health.
− The device may not be used if the environmental conditions (temperature, humidity etc.)
are not within the limits indicated in the specification.
− The device may not be used in potentially explosive environment or in an atmosphere
with chemically active substances.
4 Functions
A 4-digit LED display with 14 mm character height is located on the front of the device to
display the process value or error messages in operation (see 6) and programming
parameters in programming mode (see 7). The function buttons are positioned on the rear
part of the device.
Main functions:
− Analog input 0-5 mA, 0(4)-20 mA, 0(2)-10 V
− Measuring and displaying of a process value
− Signal scaling
− Adjustable decimal point position
− Display range -999…9999
− ON/OFF control with NPN output
− Square root function (for special transmitters)
− Digital filter
− Alarm function
− Error indication when the input signal is out of range
− Error indication when wire break or short circuit

Installation must be performed only by fully qualified personnel.
The device is designed for panel mounting in a borehole of Ø22.5 mm (see Appendix A for
dimensional drawings).
Carefully position the supplied gasket on the display rear surface. Insert the cylindrical body
of the device into the borehole and tighten the nut from the rear side of the panel.
