Solid-state operating mechanism for contactors with fail-safe control input

Supply voltage
Solid-state operating mechanism for contactors with fail-safe control input 3RT1...-.S.. for
fail-safe PLC output (relay or semiconductor) 24 V DC with supply voltage 96 ... 127 V or
200 ... 277 V AC or DC.
Operating range
Operating range 0.8 ... 1.1 x U
Control via control input 24 V DC
①
The contactor can be controlled directly via an output of a fail-safe controller (F-PLC) or of a
safety relay.
● Rated voltage 24 V DC, operating range from 16.8 V to 30.0 V
● Current consumption ≤ 15 mA
● Digital control input type 1 (IEC 60947-1, Annex S)
Connecting the supply voltage
The supply voltage for the solenoid operating mechanism must be connected to A1/A2.
