Star-delta basic module with IO-Link
The Siemens 3RA2711-1CB00 is a Sirius basic module designed for star-delta motor starting — it handles the transition from star to delta without a separate timer or relay stack. Control supply is 24V DC, and the module communicates via IO-Link for parameter setting and diagnostics. The 75 mm depth keeps the assembly within standard panel depth limits.
Wiring and environmental limits
Operating temperature spans -25 to +60 °C, storage and transport from -40 to +80 °C. The module is rated for pollution degree 3 and passes 8 kV electrostatic discharge per IEC 61000-4-2, plus 10 V/m field immunity per IEC 61000-4-3 — suitable for industrial environments with heavy switching transients. Mounting position is any orientation, and vibration resistance is 10...55 Hz at 0.35 mm.
