SIMATIC reversing motor starter — 3RK1301-0CB10-1AA3
The Siemens 3RK1301-0CB10-1AA3 is a SIMATIC-brand reversing motor starter, designed to control and protect reversing motor loads in automated industrial lines. It operates on a 24 V DC control supply (20.4...28.8 V permissible range) and integrates both PROFINET and PROFIBUS DP fieldbus protocols for direct connection to a PLC or higher-level controller without a separate gateway.
Fieldbus integration and I/O profile
Two digital inputs are onboard, with no dedicated digital outputs on the base unit — output signals are handled via the PROFINET or PROFIBUS DP process image (2 bytes each for inputs and outputs,). The control module assignment for digital input signals lets you configure start, reverse, and stop logic through the fieldbus rather than hardwired terminals. No brake control variants (24 V DC, 180 V DC, 230 V AC, 500 V DC) are fitted on this order code — if braking is needed, it must be handled externally or through a different variant.
Dimensions are 290 mm height × 130 mm width × 150 mm depth. Operating temperature range is 0...60 °C; transport and storage both tolerate -40...+70 °C. Vibration resistance is 2g, shock resistance is 5g for 11 ms — within typical industrial panel specs.
