Description
The
Pyranometer KNX PY
measures global irradiance, which is perceived as heat.
The measured current irradiance (watts per squaremetre) allows for drawing conclu-
sions on the energy input to an area during a defined period of time (kilowatt hours per
squaremetre). Both values can be read out by the
KNX PY
. Four switching outputs
with adjustable threshold values as well as additional AND and OR logic gates are
available.The sensor system, the evaluation electronics and the electronics of the bus
connection are mounted in a compact housing.
Functions:
•
Measurement of global irradiance
: The current irradiance is measured
(W/m²). The energy input to an area during a defined period of time can be read
out (kWh/m²)
•
4 threshold values
can be adjusted per parameter or via communication
objects
•
2 AND and 2 OR logic gates
with each 4 inputs. Every switching incident as
well as 8 logic inputs (in the form of communication objects) may be used as
inputs for the logic gates. The output of each gate may optionally be configured
as 1 bit or 2 x 8 bits
Configuration is made using the KNX software ETS. The
product file
can be down-
loaded from the Elsner Elektronik website on

in the “Ser-
vice” menu.
