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.
