AS-Interface reversing starter for motor control centers
Control supply is 20.4...26.4 V DC, and the main circuit operates on 340...440 V AC at 50/60 Hz.
Bus integration and mounting
AS-Interface protocol is supported natively, so the starter connects directly to an AS-i network without an external gateway — addressing, diagnostics, and I/O data pass over the yellow flat cable. IP55 protection means the unit is dust-protected and resists water jets — suitable for installation in washdown areas or enclosures where occasional hose-down cleaning occurs, though not submersible. Dimensions of 182 mm wide × 220 mm high × 145 mm deep fit standard SIRIUS 3RK4 footprint; verify panel cutout against the existing backplate if replacing a different brand or older series.
Substance prohibitance date of 05/01/2012 aligns with early RoHS compliance; the unit is RoHS-compliant and meets the substance restrictions for EU markets. No PROFIBUS or PROFINET protocol support — communication is strictly AS-Interface, so plan the network architecture accordingly if migrating from a fieldbus-based system.
