SIRIUS 3RA27 function module for IO-Link
5
■
Overview
The function modules for mounting onto contactors enable the
configuration of starters and contactor assemblies for direct-on-
line, reversing and wye-delta starting without any additional,
complicated wiring of the individual components.
They include the key control functions required for the particular
feeder, e.g. timing and interlocking, and can be connected to the
control system via IO-Link.

Selection and ordering data
Suitable contactors or reversing contactor assemblies with com-
munication interface are required (see pages 5/19 and 5/20).
Note:
When using the function modules, no other auxiliary switches are
allowed to be connected to the basic units.
1)
For prewired contactor assemblies for reversing starting with commu-
nication interface, see page 5/20. When these contactor assemblies
are used, the assembly kit for the wiring is already integrated.
2)
For complete contactor assemblies for wye-delta starting incl. function
modules, see page 5/22.
