It handles reversing duty but not direct or star-delta starting. The control supply is 24 V DC, and the module communicates over the AS-i bus — no separate control wiring for forward/reverse if the bus carries the command. A built-in varistor surge suppressor clamps inductive spikes from the contactor coil. ## Panel fit and wiring — spring terminals, 45 mm wide The module is 45 mm wide, 39 mm high, and 75 mm deep — it clips onto the contactor face and adds no extra DIN-rail width beyond the contactor itself. Mounting position is any orientation. For AWG, that's 2x 24–16. Front protection is IP20 and finger-safe per IEC 60529 — fine for enclosed panels, but not for washdown zones. ## Environmental and EMC ratings for industrial panels Installation altitude is up to 2000 m. Pollution degree 3 means it tolerates conductive dust in a typical industrial enclosure. EMC immunity includes 8 kV electrostatic discharge (IEC 61000-4-2) and 10 V/m radiated field (IEC 61000-4-3). The module is rated for industrial environment A per IEC 60947-1 for both immunity and emissions. Vibration resistance is 10–55 Hz at 0.35 mm amplitude, shock resistance 11 g for 15 ms — standard for panel-mounted gear near contactors and drives.","metaTitle":"Siemens 3RA2712-2BA00 SIRIUS AS-i Function Module","metaDescription":"Siemens 3RA2712-2BA00 SIRIUS AS-i reversing starter function module, 24 V DC control, IP20, spring terminals, 45x39x75 mm.
