The Siemens SIMATIC 3RK1301-0AB13-1AA4 is a reversing motor starter built for control cabinets on automated lines. It's a reversing starter — meaning it can run a motor forward and reverse without external contactors — and it plugs onto a terminal module for quick panel assembly. Rated for 24 V DC control supply (21.6 to 26.4 V DC, max 28.8 V), it handles the standard PLC voltage found in most SIMATIC S7 cabinets.
Pluggable on a terminal module — no hardwiring to the starter body. Mount vertical or horizontal; the vibration resistance of 2g and shock resistance of 5g / 11 ms cover most conveyor and machine-tool environments. Two digital inputs are available via the control module for start/stop or interlock signals. The 2-byte input and 2-byte output process data maps directly to a PROFINET or PROFIBUS controller — no extra gateway. Brake control at 24 V DC is not built in; add an external brake chopper if the motor needs a holding brake.
