System data

Operating and ambient conditions
Voltages according to EN 61131-2
24 V DC Process and supply voltage 24 V (-15 %, +20 %)
Protection against reverse polarity Yes
Allowed interruptions of power DC supply Interruption < 10 ms, time between 2 interruptions > 1 s
supply acc. to EN 61131-2
Important: Exceeding the maximum process and supply voltages could lead to unrecoverable damage of the system. The system could be destroyed.
Temperature
Operating -40 °C ... +70 °C horizontal mounting of modules
-40 °C ... +40 °C vertical mounting of modules and output load reduced to 50 % per group
Storage / Transport -40 °C ... +85 °C
Humidity
Operating / Storage Max. 100 %, with condensation
Air pressure
Operating 620…1080 hPa / (-1000...4000 m)
> 2000 m (< 795 hPa): max. operating temperature must be reduced by
10 °C.
Storage > 620 hPa / < 4000 m

Creepage distances and clearances
Insulation Test Voltages, Routine Test, according to EN 61131-2 AC voltage during 2 seconds
24 V circuits (supply, 24 V inputs/outputs), if they are 350 V
electrically isolated against other circuitry
The creepage distances and clearances meet the requirements of the overvoltage category II, pollution degree 2.
