n Each byte is connected with an 8 pole terminal block.
n Each output byte has its own power supply connection.
This feature can be used to turn off a whole byte using an external
switch.
n The outputs are always referenced against 0 V, located in the
power connector (X30 pin 3 Fig. 27).
– Consider that the power supply cable for one output byte has to be
chosen accordingly.
The current limitation of each output is 0.7 - 2.5 A per pin in case of
short circuits.
– Take care of this specification by appropriate output definition
toward the external actuator.
Each output has a nominal output capability of 1 A. Nevertheless each
output byte (8 signals) is globally limited to 4 A.
Outputs are monitored for faults. In case of errors, the output is
switched off. Since every 4 adjacent outputs have a common status
signal, the onboard monitor always switches off 4 outputs in such a
case (1 - 4, 5 - 8, 9 - 12, 13 - 16).
