NOTICE
The supply voltage must be present on X31:1/2 for using the digital inputs and out-
puts.
Overvoltage may damage the DH.21/41B controller. In this case, the specified func-
tion of the digital inputs and outputs is no longer ensured.
• To prevent dangerous voltage peaks from occurring, do not connect inductive
loads to the supply voltage or the digital inputs/outputs without free running diodes.
For more information on digital inputs or outputs, refer to chapter "Technical data and
dimension drawings"(→275).
