Parameter
Value
Max. length of analog cables, conductor cross sec-
tion > 0.14 mm²
100 m
Weight
300 g
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 switchgear 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 V DC.
