· Output 2: f < _ 100 Hz
Pulse duration/pulse break ~1:1
· Volume pulse value is programmable as
desired
Default: last digit in display
6.5 Combined function module
The combined module is equipped with 2 inputs and 1 output.
The pulse input specification
is the same as 6.3 above.
The pulse output specifi-
cation is the same as pulse
output 1 in 6.4 above, but
not electrically isolated.

6.6 Analogue output function module

The module contains connections for 2 passive analogue outputs,
which can be programmed as desired using the IZAR@SET soft-
ware. The outputs are marked on the terminal strip as "1" and
"2" with the respective polarity "+" and "–".
