WARNING
Uncontrolled and unpredictable operational behaviour!
Failure of certain components in electronic control systems may result in uncontrolled and unpredictable
operational behaviour.
All types of failure and the associated protection systems must be taken into account at system level.
Comply with all automation system manufacturer instructions.
5.1. Power supply
The device is powered by an external 24 V DC power supply. It is not designed to be connected to a
DC mains supply.
Before plugging in the device, ensure that the external power supply meets the required specifi-
cations (type K to 61131-2).
External power supply (24 V DC)
Supply voltage
+24 V DC SELV (
–15% / +20%)
Ripple current propor-
tion
Max. 5 %
The direct voltage level must not fall below 20.4 V.
Power consumption
ET2110W X CS: Total max. 0.6 A at +24 V DC (peak current 1.2 A)
ET2115WUX CS: Total max. 0.7 A at +24 V DC (peak current 1.2 A)
DC2110W X CM: Total max. 0.8 A at +24 V DC (peak current 1.2 A)
DC2115WUX CM: Total max. 0.9 A at +24 V DC (peak current 1.2 A)
Internal power supply
A power supply for the system electronics for an input voltage of 24 V DC (–15% / +20%) is integrated
into the device. The power supply has integrated protection against reverse polarity and surge current
protection (1.2 A).
Installation
All connections and cables must be laid so as to prevent inductive and capacitive interference
causing any damage to the device.
Ensure that the infeed lines provide adequate current and voltage carrying capacity.
