5.2.3 External voltage supply
 The external voltage supply can be used to establish PROFINET communication for
commissioning and to query the data of the digital and analog inputs.
 Furthermore the external voltage supply serves to maintain PROFINET 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.
