Note!
For stable digital output states, in particular during the starting phase of the
controller, you must use an external 24V supply for the digital outputs.
Note!
Digital inputs and digital outputs have separated reference potentials (GI and
GO). If you interconnect inputs and outputs, the reference potentials are
connected as well by an external bridge.
