3.6.3 1 step operation
The operation of the steam humidifier is con-
trolled via terminals 3 and 5 by the contact
which is to be provided on-site. The contact
only has to be suitable for low voltage.
3.6.4 Operation with external control-
ler or active humidity sensor
When the steam humidifier is controlled via
an external controller (e.g. a PLC) or an
active humidity sensor, physical control sig-
nals can be processed in the range 0...10 V,
0...20 mA or 0...140
Ω
. A separate terminal
is provided on the board for each of these
signal types (also see chapter 7, „Wiring dia-
grams). Terminal 4, "GND" is the reference
potential in each case.
Wiring examples:
Humidity sensors require an external supply
voltage. 20 VDC are available for this pur-
pose at terminal 3.
