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 supply.
Before plugging in the device, ensure it meets the specifications for external power supplies
(type K according 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.
