Configuration
6.3 Operating mechanism system / coil selection 3RT contactors and 3RH2 contactor relays
SIRIUS - SIRIUS 3RT Contactors/Contactor assemblies
82 Manual, 09/2017, A5E03656507120A/RS-AE/006
Control via relay outputs
Control via relay outputs, e.g. of:
● PLC
● SIMOCODE
The contactor can be controlled using relay outputs via the terminals H1/H2. The relay
contacts are loaded with approx. 5 mA and the control supply voltage applied to A1/A2.
Note
H2 and A1 are internally connected and are therefore on the same voltage potential.

S1
Changeover switch from automatic control, e.g. via SIMOCODE or PLC relay output, to local
control
