Weight (without terminal unit)
ca. 125 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.
Multiple overloads
No effects of multiple overloads on isolated multi-channel modules occur, as
every channel is protected individually by an internal smart high-side switch.
