Function modules without communication connection
The function module without communication connection can be used for sizes S00 to S3 of
contactor assemblies for star-delta (wye-delta) start, and it can be plugged in on the front of
the contactors regardless of the connection system selected. It comprises the following
components, which can be ordered as a complete module kit (3RA2816-0EW20).
● 3RA2912-0 basic module for star-delta (wye-delta) with integrated control logic and time
setting
● Two coupling modules with integrated connecting cable 3RA2911-0
Function modules with communication connection
The SIRIUS modular system offers 3RA27 function modules for connection to the
automation level; they are fitted with terminals for connection to AS-Interface (3RA2711) or
IO-Link (3RA2712).
Note
If the contactor assembly for star
-delta (wye-delta) starting is configured with the
-capable 3RA27 function modules, a contactor with voltage tapping (3RT2...-
-0CC0) must be used as the line contactor.
