Supply voltage
To supply the digital outputs with power, an external 24 VDC voltage source must be
connected to X6-1, Pin 1 (P24EXT2).
The reference ground of the external voltage source must be connected to X6-1, Pin 15
(MEXT2).
You will find additional information in Section "
Technical data (Page 31)".

The PROFIBUS communication time as well as the application cycle time must also be taken into
account.
Incorrect connection (polarity reversal) causes neither high level nor destruction of the outputs.
General electrical properties
● Galvanic isolation using optocouplers
● Current limitation to a maximum 500 mA
● Protection against: short-circuit, overtemperature, and loss of ground
● Automatic disconnection in case of undervoltage
