Mounting and cabling
The 8 outputs deliver load currents of up to 0.5 A, although the total current from all the outputs must not
exceed 4 A. The outputs are short­circuit proof and protected against inverse connection.
The sensors are supplied from the control voltage Us.

The digital outputs connect the binary control signals from the automation unit on to the actuators at the
process level. The 8 outputs handle load currents of up to 0.5 A, and indicate their status through light
emitting diodes. The signals are optionally connected via several KM connectors. The outputs are short­
circuit safe and protected against inverse connection.
The digital inputs acquire the binary control signals from the process level and transmit them to the higher­
level automation unit. The signal state is indicated by means of light emitting diodes. The signals are
optionally connected via several KM­connectors.
The sensors are supplied from the control voltage U
S
. The load voltage, U
P
, is required for the output drivers.
If U
P
and U
S
are used for passing the power on, the maximum current must not exceed 4 A.
