3.5.1.1 Connection Unit SK TI4-TU-BUS /-NET
The Technology Units are divided into two different groups. The BUS group includes all the Bus modules
and the I/O extension. These are connected to the SK 200E via the system bus. The NET group includes all
the mains unit modules and analog modules. This includes the 24V mains units and a PotentiometerBox to
supply the SK 200E and provide the facility for the processing of analog signals.
Because of the very wide variety of functions, these two groups of devices require different connection units.
Bus modules = SK TI4-TU-BUS
Mains Unit modules = SK TI4-TU-NET
