The 6SL3230-3YE44-1AF0 delivers 90 kW at 241 A in the C2-filtered FSF frame, with the F-suffix designating an enhanced I/O and communication configuration within the G120X lineup. The integrated C2 EMC filter provides factory-guaranteed conducted emission compliance to EN 61800-3 Category C2, while the 1-prefix DC terminals support du/dt or sine-wave filter connection for long motor cable runs. This variant is positioned for installations that value I/O flexibility alongside integrated filtering.

Three fieldbus protocols — MODBUS RTU, BACnet MS/TP, and USS — operate concurrently on the RS-485 interface. Six digital inputs, two analog inputs, one analog output, and an RS-232 port cover most pump and fan control signals without expansion modules. The 305 × 709 × 360 mm FSF enclosure mounts in a standard IP20 cabinet and handles 110% overload for 60 seconds.
