The 6SL3230-3YE20-0AB0 combines C2 EMC filtering with an IOP-2 operator panel on the 4 kW G120X FSB platform. The integrated C2 filter provides industrial-network EMC compliance out of the box — no external filter to specify, wire, and house. The IOP-2 adds a graphical display with plain-text diagnostics, making this the most self-contained 4 kW G120X variant without DC terminals: compliant filtering plus local HMI in one part number.
