It communicates via IO-Link, which means the PLC gets back diagnostic data — coil health, switching cycles, load current — through the same 24 V DC control wire, without adding a fieldbus node. ## Termination and wiring — spring-loaded terminals Auxiliary and control circuits terminate via spring-loaded terminals — no screw torque to check, no loosening under vibration. Accepts 1x or 2x conductors from 0.25 to 1.5 mm² with or without ferrule, and 2x AWG 24 to 16 for the auxiliary contacts. The front face carries IP20 finger-safe touch protection per IEC 60529 — safe for vertical access from the front, which matters when the panel door is open and someone reaches in. ## Environmental and EMC — built for the panel Rated for industrial EMC environment A per IEC 60947-1 — that means it's designed for the noise floor of a factory floor, not a quiet office. Electrostatic discharge immunity tested to 8 kV contact and radiated field immunity to 10 V/m. Vibration resistance is 10 to 55 Hz at 0.35 mm amplitude; shock tested at 11 g for 15 ms. Mount in any position.","metaTitle":"Siemens 3RA2711-2BB00 Sirius Motor Starter, IO-Link, 24V DC","metaDescription":"Siemens 3RA2711-2BB00 Sirius basic module for reversing starters.
