Operating temperature:
from -10 to 60 °C (from 14 to 140 °F).
Storage temperature:
from -20 to 70 °C (from -4 to 158 °F).
Operating humidity:
from 10 to 90% of relative humidity not condensing.
Pollution situation:
2.
Power supply:
24 VAC +10% -15%, 50/60 Hz ±3 Hz, 40 VA max. not isolated or
24... 37 VDC, 22 W max. not isolated, supplied by a class 2 circuit.
If the device is powered in direct current, it is necessary to respect
the polarity of the power supply voltage.
Protect the power supply with a fuse rated 2 A-T 250 V.
Overvoltage category:
III.
Analog inputs:
4 inputs of which 2 inputs (non optoisolated, which can be set via
configuration parameter for NTC/Pt 1000 probes and for 0-20
mA/4-20 mA/0-5 V ratiometric transducers) which can be set via
configuration parameter for suction temperature backup
probe/suction pressure backup probe, 1 input (non optoisolated,
which can be set via configuration parameter for NTC/Pt 1000
probes) as suction temperature probe and 1 input (non
optoisolated, which can be set via configuration parameter for
0-20 mA/4-20 mA/0-5 V ratiometric/0-10 V transducers) as suction
pressure probe.
