Do not connect any voltages externally to digital outputs!
This ist not intended usage.
Reason: Externally voltages at one or more terminals DC0...DC7 or
DO8...DO15 may cause that other digital outputs are supplied through that
voltage instead of voltage UP3 (reverse voltage).
This is also possible, if DC channels are used as inputs. For this, the source for
the input signals should be the impressed UP3 of the device.
This limitation does not apply for the input channels DI0..DI7.
CAUTION!
Risk of malfunction by unintended usage!
If the function cut-off of the digital outputs is to be used by deactivation of the
supply voltage UP3, be sure that no external voltage is conncted at the outputs
DO8...DO15 and DC0...DC7.
