Structure of a compact starter group
Up to 4 compact starters can be connected to one IO-Link master. For this purpose, connect
the first compact starter direct with the IO-Link master. You connect the 3 other compact
starters in series with each other. A 14-core connecting cable (8 mm) is available for this
purpose.
The representation below shows how the compact starters are connected to each other.
