Fig.4-13: Calculating the power consumption of an example system
According to the calculation, approx. 320 W are required for 24 V DC ± 20%,
and approx. 35 W are required for 24 V DC ± 5%. If less than the maximum
possible 2 A is used for each of the outputs X81, X71 and X72, the power
consumption can be reduced accordingly.
● Use an AC-adaptor or a PELV-protected control transformer
according to
IEC 60204-1 (Section 6.4) for the 24-V control
voltage supply.
● Overvoltages exceeding 33 V must be discharged by means
of measures in the electrical equipment of the machine or
plant. Such measures include AC-adaptors and overvoltage
limiters which are provided at the input of the control cabinet
and limit incoming overvoltages. This also applies to longer
24-V lines which are placed in parallel to power and line supply
cables and are able to receive overvoltages through inductive
or capacitive coupling.
● Please be absolutely sure to observe the instructions on
grounding of the 24-V control voltage supply described in
chapter "Grounding Concept" on page 34.
● A current of 0.5 A can be delivered at each digital output.
However, the sum total of all currents may not exceed 2 A per
terminal (BYTE).
