Parameter Value
Max. cable length
Shielded 1000 m
Unshielded 600 m
Technical Data of the Configurable Digital Inputs/Outputs
Each of the configurable digital I/O channels can be defined as input or output by the user pro-
gram. This is done by interrogating or allocating the corresponding channel.
Parameter Value
Number of channels per module 8 inputs/outputs (with transistors)
Distribution of the channels into groups 1 group for 8 channels
If the channels are used as inputs
Channels DC8...DC15 Terminals 4.0...4.7
If the channels are used as outputs
Channels DC8...DC15 Terminals 4.0...4.7
Indication of the input/output signals 1 yellow LED per channel, the LED is ON when
the input/output signal is high (signal 1)
Electrical isolation Yes, per module
Technical Data of the Digital Inputs/Outputs if used as Inputs
Parameter Value
Number of channels per module 8
Distribution of the channels into groups 1 group of 8 channels
Terminals of the channels DC8 to DC15 Terminals 4.0 to 4.7
Reference potential for all inputs Terminals 1.9...4.9 (Minus pole of the supply
voltage, signal name ZP)
Indication of the input signals 1 yellow LED per channel, the LED is ON
when the input signal is high (signal 1)
Input type (according EN 61131-2) Type 1
