Configuration
6.2 Configuration
SIRIUS 3RA28 function modules for mounting on 3RT2 contactors
34 Manual, 02/2019, A5E03656507620A/RS-AD/005
6.2 Configuration
3RA2811-.CW10
The function module is controlled via the terminal A3 and the internal contacts of the
contactor A2. After expiry of the time t, the semiconductor becomes conductive and switches
on the contactor Q.
Note
Contactor coil terminal A1 must not be connected.
3RA2831-.D.10
The 3RA2831 function module is connected to voltage via A3, A4. After expiry of the time t,
the semiconductor becomes conductive and switches on the contactor Q.
Note
Contactor coil terminals A1 and A2 must not be connected.
