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.
