In addition to the SIRIUS 3RA6 compact starter which can be easily connected to the IO-Link master via a standardized IO-Link connection, we offer 3RA27 function modules for connecting to IO-Link. These function modules can be fitted directly onto the 3RT2 SIRIUS contactors and in no time at all whole groups of load feeders are capable of communication. Up to four SIRIUS load feeders (direct-on-line, reversing and star-delta (wye-delta) starters) can be combined in a group and thus occupy a port on the IO-Link master as an IO-Link device.
