6.3 Operating mechanism system / coil selection 3RT contactors and 3RH2 contactor relays
6.3.2.4 Solid-state operating mechanism for contactors with extended operating range and rail
applications
Supply voltage
Solid-state operating mechanism for contactors with extended operating range and rail
application 3RT1...-.X..-0LA2 for PLC output
24 ... 110 V DC with supply voltages 24 V DC, 72 V DC and 110 V DC.
Operating range
Operating range 0.7 ... 1.25 x U
Control via control input 24 ... 110 V DC
①
②
The contactor can be operated direct via an output of a controller (PLC).
● Rated voltage 24 ... 110 V DC, operating range from 16.8 V (0.7 • 24 V) to 137.5 V
(1.25 • 110 V),
ON > 16.8 V / OFF < 8 V / 8 V to 16.8 V unspecified
● Current consumption < 2 mA
Connecting the supply voltage
The supply voltage for the solenoid operating mechanism must be connected to A1/A2.
Note
The slide switch on the front side of the withdrawable coil must be switched to the "ON"
position before commissioning (factory default setting is "OFF").
