1. INTRODUCTION
The DP* series temperature and humidity sensors repre sent the latest version of the CAREL sensors for rooms, industrial environments and ducts,
developed for the residential and light industrial HVAC/R market, with the quality that CAREL stand out for.
The range includes models with 0 to 10 V output and with RS485 serial output (Carel or Modbus).
The DP* series sensors use sensors with a digital output, and featu re a wider temperature and humidity range than the previous models, ensuring all
the versatility required by the applications in the specific market, with excellent and quality / price ratio.
These sensors are typically used together with the Carel controllers, however they can also be used with third party devices.
1.1 General features
The CAREL electronic temperature and/or humidity sensors have been developed for applications in the heating, refrigeration and air-conditioning
sectors.
The following models are available: a) wall, b) industrial environment, c) duct. The various models differ due to the different active outputs (current or
voltage, selectable by jumpers) except for the models with NTC resistive temperature output (hereinafter indicated as “NTC res.”), compatible with
CAREL controllers. A model is also available with optically-isolated RS485 serial output for connection to the serial line (pCO or Carel supervisor).
The sensors can have an alternating current (12 to 24 Vac) or direct current (9 to 30 Vdc) power supply.
Wall sensors (DPW*)
These are used in heating and air-conditioning systems. Their design makes them suitable for use in the home. Ready for wall-mounting.
Sensors for industrial environments (DPP*)
These are used in industrial environments (cold rooms, pools etc.) where a high index of protection is required, both for the case (IP55) and the
sensors (IP54). Ready for wall-mounting.
Duct sensors (DPD*)
These are used in ducted heating and air-conditioning systems. Supplied together with a fastening bracket.

4.6 Power supply connection
For alternating current power supply (12 to 24 Vac), just one transformer can be used, connected to G-G0 on all the sensors with G0 to earth, paying
special care to observe the polarity by connecting together the terminals with the same name, or alternatively using an isolating transformer for each
individual sensor.
For the serial sensors, the type of power supply depends on the model of sensor used:
sensors with optical isolation can be powered with one power supply, G-G0, for all the sensors as well as for the controller. In this case, make sure that
the cable shield on the controller side is connected to EARTH, directly or via the G0-Earth connection on the controller.
Sensors that are NOT isolated: for short distances, these can be powered with one power supply, for distances over 10 m, an isolating transformer may
be required for each sensor.
4.7 Wiring
For wiring a shielded multicore cable with 3 to 5 wires, depending on the model.
The maximum cross-section of the wires allowable for the terminals is 1.5 mm
2
. In versions DPP* and DPD*, the maximum inside diameter of the cable
gland is 8 mm.
Serial version with RS485 output
For sensors with serial connection, the cable use must have the following characteristics:
− twisted pair;
− shielded, preferably with earth wire;
− size AWG20 (diam. 0.7 to 0.8 mm; area 0.39 to 0.5 mm²) or AWG22 (diam. 0.55 to 0.65 mm; area 0.24 to 0.33 mm²);
− rated capacitance between the wires <100 pF/m.
Analogue version with 0 to 1 Vdc or -0.5 to 1Vdc output signal
On the models with active outputs (not NTC res.) configured for voltage signals, the voltage drop over the cables must be kept in mind: the effect of the
drop over 1 mm
2
in cross-section means a variation of 0.015 °C for each metre of cable (0.015 °C m/mm²) in the temperature measurement, and a
variation of 0.015% rH for each metre of cable (0.015% rH m/mm2) in the humidity measurement.
Below is an example that shows the calculation of the variations that cause temperature and humidity errors.
Example:
Cable length Cable cross-section Temperature error Humidity error
30 m 0.5 mm2 0.9 °C 0.9% rH
30 m 1.5 mm2 0.3 °C 0.3% rH
To avoid measurement errors due to the supply current, an additional power supply from an external transformer can be used (CAREL transformer
codes TRA12VDE00 or TRA2400001), to be connected as shown in the figure (2’ with transf.). With this configuration the maximum distance is 100 m
(note
1
)
The transformer must not be earthed and can be installed in the panel together with the controller. The connection cable must be multicore with 4 or 5
wires. In this situation, no supply current runs through connection M(G0). In installations with multiple sensors, use a transformer for each sensor to
avoid measurement errors.
Analogue version with 4 to 20 mA output signal
For distances over 30 m, the current output should be selected, if the system allows. The maximum installation distance for the current output is 200 m
(note
1
).
In the case of AC power supply, the wires used must have a cross-section of 1.5 mm
2
to reduce noise due to the supply current. Such noise may, in
some cases, cause instability in the measurement, which can be eliminated using a DC power supply or with an additional power supply, as shown in
the figure (2’ with trasf.).

4.8 Functional notes and differences between DP and AS sensors (with analogue output)
On power-up, the DP sensors (excluding the serial and NTC te mperature sensors) provide an output value (voltage or current) that is out-of-range (with
a negative value), and that stabilises at the final reading in a maximum of 20 to 30 s. If the controllers feature alarm signals for readings that are out-ofrange, such signals may be activated, however they are cancelled in the time indicated.
For the digital measurement of the signal between the main board and the sensor board, a temperature and humidity meas urement refresh period of
15s is used, which may introduce a delay in the reading.
If the outputs (voltage and current) are overloaded, the output is reset for a minimum measurement cycle (15 s).
Communication errors with the sensor board also reset the outputs.
The condition with 0 V output can be used to manage sensor errors on the controllers, and is av ailable for 0 to 1 V, 0 to 10 V and 4 to 20 mA outputs,
yet not for -0.5 to 1V.
WARNING!
The sensors are configured by default with 4 to 20 mA output. Before connecting to the controller, check the compatibility of the input. To set a different
configuration on the sensor, change the default configuration.
On sensors with temperature and humidity output, both channels are configured in the same way, and mixed connections of the outputs are not
possible. For 0 to 1 V, 0 to 10 V and 4 to 20 mA outputs, the start and end scale values are different from the AS* series analogue sensors (see the table
below).
Sensors with normalised output: 0 to 1 V / 0 to 10 V / 4 to 20
mA
-30 to 70°C 0 to 100% rH
0 to 1 V 0 to 1 V
0 to 10 V 0 to 10 V
4 to 20 mA 4 to 20 mA
Sensors with output: -0.5 to 1V
-30 to 70°C 0 to 100% rH
-0.3 to 0.7V 0.0 to 1 V
Start and end range limits to be set on the controllers. These are independent of the effective range of measurement.
Example. For code DPWC110000 (-10 to 60°C and 10 to 90% rH)
For 0 to 1 V, 0 to .10V, 4 to 20 mA outputs set:
0 to 1 V 0V at -30°C and 0% rH … 1V at 70°C and 100% rH
0 to 10 V 0V at -30°C and 0% rH. … 10V at 70°C and 100% rH
4 to 20 mA 4mA at -30°C and 0% rH … 20mA at 70°C and 100% rH
For -0.5 to 1V output (the limits generally do not need to be set)
-0.3V at -30°C …. +0.7V at 70°C
0V at 0% rH … 1V at 100% rH

4.10 General warnings
• To maintain the index of protection declared in the versions with “IP55” case, the wiring must use multicore cables, with the outer sheath having a
maximum diameter of 8 mm.
• It is recommended to use shielded cables. The cables carrying the temperature and humidity signals must not run
near the 115 to 230 or 400 to
480 Vac power cables, or near cables that power from the contactors to the loads. Measurement errors due to electromagnetic coupling must be
avoided.
• The sensor power supply and electrical signals are very low v oltage, nonetheless for connection t o the controllers, remember th at supplementary
electrical insulation is required, excluding the “se nsor protection” cap. The metal protection of the sensors is connected to the sensor power
supply reference. For conformity to the safety standards, double ins ulation must used for the power supply to the sensor and the controller it is
connected to, if the sensor zone is accessible to the user in the installation.
The sensors can integrated into Class 1 or 2 equipment, with the following warnings:
Class 1:
- the power supply reference G0 must be earthed.
Class 2:
- double insulation or reinforced insulation must be used for the power supply to the sensor and the controller it is connected to. If this is not
possible, in normal use, the sensor zone must be made inaccessible to the users.
• Do not expose to sources of heat or direct sunlight.
Note:
For the connection of the analogue outputs at distances over 30 m, the installer must make sure that the suitable precautions and protectors specified
have been applied in compliance with the standards, so as to avoid faults due to surge. Depending on the installation, the shield of the analogue signal
connection cables may need to be earthed.

6. WARNINGS FOR THE REPLACEMENT OF THE AS* SERIES
The size and fittings of the DP series* sensors are compatible with the AS* series. Specifically:
model ASW is perfectly compatible with model DPW*
for model ASP*, the outside dimensions and the drilling template are different than for model DPP*.
for model ASD*, the outside dimensions are different, while the fastening flange remains unchanged for model DPD*
For the 0 to 1 V, 0 to 10 V and 4 to 20 mA outputs, the start and end scale values are different from those on the AS* series analogue sensors. For
further information, see the chapter Functional notes and differences between DP and AS sensors.
