Parameter Value
Current consumption from 24 V DC power supply at
the L+/UP and M/ZP terminals of the CPU/commu-
nication interface module
Ca. 5 mA
Galvanic isolation Yes, between the input group and the
output group and the rest of the module
Isolated groups 3 groups (1 group for 8 input channels, 2
groups for 8 output channels)
Surge-voltage (max.) 35 V DC for 0.5 s
Max. power dissipation within the module 2.3 W
Weight Ca. 150 g
Mounting position Horizontal or vertical
Cooling The natural convection cooling must not
be hindered by cable ducts or other parts
in the switchgear cabinet.
No effects of multiple overloads on isolated multi-channel modules occur, as every channel is
protected individually by an external fuse.
