5.2.5 External voltage supply
By means of the external voltage supply, PROFIBUS communication for commissioning
can be established, and the data of the digital and analog inputs can be queried.
Furthermore the external voltage supply serves to maintain PROFIBUS communication
if the main supply fails.
The digital inputs RFR, DI1 ... DI5 and the analog input can continue to be evaluated.
The external voltage supply is done via the terminals 24E and GND of the terminal strip
X3.
Permissible voltage (DC) / max. current:
– U = 24 V DC (20 V - 0 % ... 29 V + 0 %)
–I
max
= 400 mA
Access to parameters of a device that is disconnected from the mains is not possible.
