WARNING
Uncontrolled and unpredictable operational behaviour!
Failure in certain components in electronic control systems may result
in uncontrolled and unpredictable operational behaviour.
▶
All types of failure and the associated fuse systems are to 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 specifications (type
K to 61131-2).
External PLC power supply (24 V DC: L+; L1+; L2+; L3+; L4+)
Supply voltage
+24 V DC SELV (–15% / +20%)
Alternating current proportion
Max. 5%
The direct voltage level must not fall below 20.4 V.
Energy buffering
Power fail 10 ms
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).
▶
Fuse the supply lines for the IO lines (L1+ to L4+) externally so that the value (approx. 5 A) for the power-
limited electrical circuits (150/U) are not exceeded (U = value of the voltage applied).
Installation
▶
All connections and cables must be laid out 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.
