WARNING
Uncontrolled and unpredictable operational behaviour!
The failure of 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.
Follow the automation system manufacturer’s instructions.
5.1. Power supply
The device is powered by an external 24 V DC power supply.
Before plugging in the device, make sure that the external power supply meets the required
specifications (type K to DIN EN 61131-2).
External power supply (24 V DC)
Supply voltage
+24 V DC SELV (-15% / +20%)
AC voltage component
Max. 5%
The DC voltage level must not fall below 20.4 V.
Power consumption
Total max. 3.2 A at +24 V DC (1.2 A electronics; 2 A AIO)
Power buffering
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 unit has built-in reverse polarity protection and surge current protec-
tion (1.2 A).
Installation
All connections and cables should be set up in a way that prevents interference and capacitive
interference to the device.
Make sure that the current and voltage resistance of the supply cables are sufficient.
