It snaps onto the front of a communication-capable contactor (3RT20…-…..-0CC0) in sizes S00, S0, S2, or S3, turning a basic reversing contactor pair into a networked device that reports status and accepts commands over IO-Link. The module is designed specifically for reversing starters, meaning it handles the interlocking and control logic for two contactors that swap motor phase rotation. It is not for direct-on-line or star-delta configurations. ## IO-Link interface and control supply Control power is 24 VDC, and the module communicates via IO-Link. There is no AS-Interface variant here — this is an IO-Link-only interface. The surge suppressor is a varistor, integrated into the module. The control circuit interface with IO-Link means the module can pass process data (start/stop, direction, fault) and parameter data (e.g., restart behavior, current limits) to an IO-Link master. This eliminates discrete I/O wiring for the reversing function — one M12 cable carries both power and data. No DIN rail is required for the module itself — it rides on the contactor, which is DIN-rail mounted. The assembly fits a 45 mm width, 37 mm height, and 75 mm depth. Wiring is via screw-type terminals for auxiliary and control circuits. The terminals are removable, which helps when pre-wiring panels on the bench. Solid wire range is 0.5 to 4 mm² for a single conductor, or 2x 0.5 to 2.5 mm² for two conductors. With ferrules, the range narrows to 1x 0.5 to 2.5 mm² or 2x 0.5 to 1.5 mm². AWG for auxiliary contacts is 2x 20 to 14. ## Environmental and EMC Vibration resistance is 10 to 55 Hz at 0.35 mm; shock resistance is 11 g for 15 ms. Installation altitude max is 2000 m above sea level. EMC immunity is per IEC 60947-1, environment A (industrial). Emitted interference meets CISPR 11, environment A. Electrostatic discharge immunity is 8 kV per IEC 61000-4-2.","metaTitle":"Siemens 3RA2711-1BA00 Sirius IO-Link Function Module, Revers","metaDescription":"Siemens Sirius 3RA2711-1BA00 function module for IO-Link reversing starters.
