4.3.5 Digital outputs I/O’s (IQQx)
The modules
SMX100-2(/2), SMX100-4(/2)
SMX131(/2), SMX131R(/2), SMX131R-4/2
SMX132-x(R)/2/D
respectively have configurable safe digital I/O's in different numbers (see chapter 3 module
overview). This connection acts as safe digital pp-switching output parameterized as output
(IQQx).
