SIMATIC reversing starter, CLASS 10, 24 V DC, PROFINET
The Siemens SIMATIC 3RK1301-0AB10-1AA4 is a reversing motor starter designed for 24 V DC control circuits, with a rated supply voltage range of 20.4 to 28.8 V DC. This unit integrates both PROFINET and PROFIBUS DP protocols, so it can be addressed directly from a PLC without a separate gateway. The digital inputs (2 total) are wired through the control module, and the I/O mapping allocates 2 bytes each for inputs and outputs. Pollution degree 3 at 400 V per IEC 60664 means it's rated for conductive pollution environments typical of control cabinets near production floors.
Mounts via pluggable connection onto a terminal module — no hardwiring to the base unit. Fastening method is pluggable on terminal module, so the starter can be swapped without disturbing the main power wiring. Acceptable mounting positions are vertical or horizontal. Dimensions: 290 mm height, 130 mm width, 150 mm depth. Vibration resistance is 2g; shock resistance is 5g for 11 ms.
