s
Max. power dissipation within the module
6 W (outputs OFF)
Weight (without terminal unit)
ca. 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.
No effects of multiple overloads on isolated multi-channel modules occur, as every channel is
protected individually by an external fuse.
