2.1 General description
The C520/C520X / R520/R520X are intelligent two-wire universal transmitters for measurement
with up to two user programmable channels in single, differential, average, minimum or
maximum mode.
The C520/C520X / R520/R520X are intended for:
• Temperature measurements with single or dual resistance thermometers
• Temperature measurements with single or dual thermocouples
• Temperature measurements with one resistance thermometers and one thermocouple
• Temperature difference measurements with resistance thermometers
• Measurements with potentiometers
• Voltage measurements in a range -10…1000 mV
To increase reliability and stability of the system, C520/R520 transmitters have dual sensor
inputs.
The dual sensor inputs enable new safety features such as sensor redundancy and sensor drift
monitoring.
C520S/C520XS/R520S/R520XS are reviewed by exida according to IEC 61508-2:2010 and by SP
for full assessment according to IEC 61508-2 and -3:2010 for use in SIL 2 rated Safety
Instrumented Systems (SIS). For safety instructions see the safety manual.
The C520 and R520 are the standard versions for use in safe (non-hazardous) areas.
The C520X and R520X are Intrinsically Safe versions for use in areas with potentially explosive
atmospheres, Zone 0 (only C520X), 1 and 2.
The C520 and C520X are designed for installation in a B connection head according to DIN EN
50446 or larger.
The R520 and R520X are designed for installation on a 35 mm top-hat rail according to
EN 60715.
The two-wire universal C520/C520X / R520/R520X transmitters are HART® 5 and 6-compatible.
Configuration of the C520/R520 transmitters is possible with:
• HART® 5 and 6 protocol via 4…20 mA output circuit
• HART® 5 and 6 handheld terminal
• The graphic user interface DTM
• The third part PC software with a FSK modem for HART® 5 and 6 communication
• PC configuration software ConSoft with PC Configuration Kit - ICON
The PC configuration software ConSoft is used for configuration, display and documentation.
The current ConSoft version is available for downloading on our website www.inor.com.

3.1 Installation of the C520/ C520X
The C520/C520X is intended for installation in DIN B connection heads or larger. The large
Ø7 mm / 0.28” center hole (see Chapter 6.1.3) facilitates the electrical connection of the
measurement sensor and the installation.
Figure 4: Connection head installation kit 70ADA00017
In potentially explosive areas, the C520X must be used.
The transmitter C520X must be supplied by an intrinsically safe power supply unit or Zener
barrier placed outside of the potentially explosive zone.
The C520X transmitter must be installed in a housing with the protection rating IP20 or better
according to EN 60529 / IEC 60529.
When mounted in a zone 0 location (which is allowed for a 1 G (Ga) equipment), precautions
shall be taken into account when the enclosure material is light metal (protect against impact
and friction that can cause ignition capable sparks) or non-conductive non-metallic material
(protection against electrostatic discharge).

Ambient temperature considerations
•
The C520/C520X temperature transmitter has been developed for an ambient
temperature range from -40 to 85°C (-40 to +185°F). Please also note that the ambient
temperature is also dependent on the temperature category in Section 6.2.5, Ex data of
the ambient temperature.
The process temperature is also transferred to the transmitter housing via the protective tube.
If the process temperature is close to or exceeds the maximum specified process temperature,
then the temperature in the transmitter housing can rise above the maximum permissible
ambient temperature. Always check that the ambient temperature where the transmitter is
installed is always within the permissible range. One way to decrease heat transfer via the
protective tube is to make the protective tube longer or in general to install the transmitter
farther away from the heat source. The same safety measures can be taken if the temperature
is below the specified minimum temperature.

04/2018 • 86B5200001 / version 5.2 www.inor.com 12
3.2 Installation of the R520/ R520X
The R520 / R520X transmitter is intended for installation on a 35 mm top-hat rail according to
EN 60715.
Figure 5: Rail installation
1 Fix the upper part of the transmitter onto the rail.
2 Press the lower part of the transmitter against the rail.
3
To remove the transmitter, bend the locking device using a small screwdriver. Carefully pull the
transmitter in the forward direction.
In potentially explosive areas, the R520X must be used.
The transmitter R520X can be installed in potentially hazardous area Zone 1 and 2 and the input
may be connected to Zone 0. R520X must be supplied by an intrinsically safe power supply unit
or Zener barrier placed outside of the potentially explosive zone.
The R520X transmitter must be installed in a housing with the protection rating IP20 or better
according to EN 60529 / IEC 60529.
The R520/R520X temperature transmitter has been developed for an ambient temperature
range from -20 to 70°C (-4 to +158°F). Please also note that the ambient temperature is also
dependent on the temperature category in Section 6.4.5, Ex data of the ambient temperature.

04/2018 • 86B5200001 / version 5.2 www.inor.com 13
Any work on the device may only be performed by trained and qualified personnel. The regional
industrial safety and other safety regulations must always be observed.
Observe the national regulations for electrical installations!
Any work on the electrical connections may only be performed in the de-energized state.
Observe the voltage specifications on the rating plate!
Observe the relevant installation regulations in your country!
The transmitter is protected against polarity reversal. No damage will occur to the device if the
polarity of the supply voltage is switched. The output will then indicate 0 mA.
When connecting devices with an Ex certificate, the corresponding chapters and the instructions
in this manual must be observed.
The transmitter must be supplied with an intrinsically safe power supply unit or Zener barrier
outside of the potentially explosive zone.
The Communication port (USB connection) may only be connected to the associated ICON
Interface if the temperature transmitter is outside the hazardous area and with no sensor
connected to it that is in the hazardous area.
For the applicable ambient temperature range, refer to section 6.2.5 respectively 6.4.5.
The transmitter shall be mounted into a suitable enclosure that provides a degree of protection
of at least IP20.
4.2 C520/C520X connections
The input and output signals and the power supply must be connected in accordance with the
following illustrations. The transmitter is easy to install with the Inor connection head
installation kit (see ordering information Chapter 7.1). To avoid measuring errors, all cables
must be connected properly and the screws tightened correctly.
