) 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.
