For direct control of relays, contactors, mag-
netic valves, signallers, horns etc. It must not
be operated without connected load (con-
nected in series) as the oscillator would be
destroyed if directly connected to mains. Not
suitable for connection to low voltage PLC-
inputs. The domestic current is briefly low-
ered below 1 mA when switching off the load,
so that contactors, the holding current of
which is lower than the permanently flowing
domestic current of the electronics, neverthe-
less can be switched off reliably.
Floating transistor output (CAP E30 T)
Voltage supply: 10 … 55 V DC
(for further information see the following
switching examples as well as the technical
data)
Switching examples
The transistor switches the supply voltage of
the oscillator to the binary input of a PLC or to
an electrical load. Through different connec-
tion of the consumer (load), PNP or NPN
action can be preset.
The transistor switches a second voltage
source with the same reference potential to
the binary input of a PLC or to an electrical
load. Through different connection of the
consumer (load), PNP or NPN action can be
preset.

The transistor switches a second, galvani-
cally separated voltage source to the binary
input of a PLC or to an electrical load.
Through different connection of the consumer
(load), PNP or NPN action can be preset.
