4.1 DC voltage version with M12 connector
P01-PTx3xxxx-04-xx-xx-xx-002
Fig. 3: Ceraphant T with M12x1 connector
A1: 1x PNP switch output
A2: 2x PNP switch outputs R1 and m (R2)
A2’: 2x PNP switch outputs R1 and m (diagnosis/break contact with adjustment "DESINA")
A3: PNP switch output with additional analog output (active)
A3’: PNP switch output with additional analog output (active) (PIN assignment with "DESINA" setting)
"
Caution!
To avoid the analog input damaging of a PLC, do not connect the active PNP switch output of
the device to the 4...20 mA input of a PLC.
!
Note!
DESINA (see  Chap. 6.2 Basic settings):
