* Contact output, passive, optocoupler
The function of the optocoupler for the pulse output
can be changed over using software.
It may either function as a pulse output or contact output.
The changeover function is only available with the version with a
display!
One of the following statuses can be signalled in the "contact out-
put" function:
Inlet/outlet signalling, min./max. contact, system alarm.
If working with the version without a display, the opto-electronic
coupler function can only be set as "pulse output" or "inlet/
outlet signalling".

Contact input
The input is considered as actuated at an external
voltage of between 16 V ≤ U
CEH
It is considered as non-actuated at a voltage level of between
0 V ≤ U ≤ 2 V DC. The internal resistance of the
CEL
contact input is: Ri = 2 kOhm.
