Overview
3SK2 basic units
The 3SK2 basic units have a large number of inputs and outputs
within a narrow width. In addition, demanding safety applica-
tions can be implemented simply with several independent
safety functions. Flexible application options are enabled by
powerful semiconductor outputs, as well as by expandability
with additional 3SK output expansions and 3RM1 Failsafe motor
starters. Flexible time functions and diagnostics options are
available.
