SIRIUS MCU reversing starter, I/O controlled
Enclosure is IP55, so the unit is dust-protected and can handle water jets from any direction — suitable for installation in washdown areas or outdoor cabinets where the starter is exposed to hose-down cleaning. The operating voltage range is 340 to 440 V AC, covering 400 V nominal systems with tolerance.
Control supply and fieldbus note
Control supply voltage is 20.4 to 26.4 V DC, so you need a 24 V DC power supply in the panel — no AC control voltage option here. The unit has no digital inputs onboard (0 digital inputs), which means the I/O control signal comes from an external controller or PLC via hardwired connections. There is no PROFIBUS DP, no PROFINET, no AS-Interface, and no bus communication support on this variant — it's a pure hardwired I/O reversing starter. If you need fieldbus integration, you'd look at a different SIRIUS MCU order code with the communication module built in.
