Parameter Value
Mounting position Horizontal or vertical with derating (output
load reduced to 50 % at 40 °C per group)
Cooling The natural convection cooling must not be
hindered by cable ducts or other parts in the
switch-gear cabinet.
NOTICE!
Attention:
All I/O channels (digital and analog) are protected against reverse polarity,
reverse supply, short circuit and continuous overvoltage up to 30 VDC.
