The following options are available:
The switch works as NO or NC
contact. If the set point is exceeded,
the output signal is set. If the
measuring signal falls below the
reset point the output signal is reset.
NO contact is to be understood in the
following way: the PNP switching
output is closed if temperature is
above switching point
if level falls below reset point
NC contact is to be understood in the
following way: the PNP switching
output is open if the temperature is
above switching point
if level falls below reset point
see as well figure below
The switch works as NO or NC
contact. The limits of the window are
set by and . If the measuring
signal reaches the window the
output signal is set. If the measuring
signal leaves the window the output
signal is reset.
NO contact is to be understood in the
following way: the PNP switching
output is closed if the temperature is
within the window limits. Otherwise it
is open.
NC contact is to be understood in the
following way: the PNP switching
output is open if the temperature is
within the window limits. Otherwise it
is closed.
In this case, a square wave signal
with a frequency between 1 Hz and
100 Hz in proportion to the
measuring signal is set at the output.
Note: In order to increase the slope
of the square wave, we recommend
loading the switching output with a
10 k resistor.
