5.8 Voltage supply for external devices (+24V, GND)
There is an integrated power supply for external devices, e.g. a sensor. Te24 V, output voltage

Technical data.
It is not permissible to connect outputs of several devices to each other!
In case of overload or short circuit (24 V
–
GND), the external power supply is shut down (multi-fuse).
The device performs a
“
Reset
”
and continues operation.

oating contacts, a low voltage of approx. 24 V DC is connected.
Attention!
No disconnection (isolation) when turned off, in accordance with VBG4
§

Never apply line voltage to the digital input!
It is not permissible to connect inputs of several devices to each other!
5.10 Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
earthed conductor. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50V (between
“
GND
”
terminals and
“
PE
”
earthed conductor). If necessary,
a connection to the earthed conductor potential can be established, install bridge between
“
GND
”
terminal and the
“
PE
”
connection (terminal for screening).
