9. Output Characteristic (only for 24 V
DC
)
The output characteristics can be set by the output selector switch.
NPN output:
The semiconductor output switches to GND (GROUND =
0 V
DC
) or is highly resistant. The maximum output current is
400 mA.
The reference point for the NPN-output is +24 V
DC.
PNP-output
The semiconductor output switches to +24 V
DC
or is highly
resistant. The maximum output current is 400 mA. The
reference point for the PNP-output is GND
(GROUND = 0 V
DC
).
Output function
N/O function
In the N/O function the output switches into the low resistance state.

Break down power supply
off
It is recommended to operate with the N/O switch output because in case of
system flow being above the flow set point - which means that the N/C switch is
de-activated - and the power supply breaks down the output switch will not be
able to switch an "ALARM" anymore.
