SIRIUS 3RA27 function modules for AS-Interface
4
■
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 the bus system.
