System data

Operating and ambient conditions
Voltages according to EN 61131-2
24 V DC Process and supply voltage 24 V DC (-15 %, +20 % without ripple)
Absolute limits 19.2...30 V inclusive ripple
Ripple < 5 %
Protection against reverse polarity Yes
Allowed interruptions of power supply DC supply Interruption < 10 ms, time between 2 interruptions > 1 s
acc. to EN 61131-2
Important: Exceeding the maximum power supply voltage (> 30 V DC) for process or supply voltages could lead to unrecoverable damage of the system. The system could be destroyed.

0…40 °C (vertical mounting of modules and output load reduced to 50 % per group)
Storage -40...+70 °C
Transport -40...+70 °C
Humidity Max. 95 %, without condensation
Air pressure Operation > 800 hPa / < 2000 m
Storage > 660 hPa / < 3500 m
