5.3 Switching output
All pyrometers of the PA Series feature two switching outputs which can
be configured as digital outputs or digital inputs. The open collector out-
puts allow for a voltage of +24 V DC. The maximum current of each open
collector output is 30 mA.
See Chapter 7.2 for more information configuration.

6.1 General installation tips
Install the pyrometer in a location where it will not be unnecessarily ex-
posed to smoke, ambient heat or water vapour.
A false reading (too low) will be displayed when the pyrometer lens is
dirty. Therefore always ensure that the lens is clean.
