The input accepts 380-480 VAC three-phase, 47-63 Hz, unfiltered, so it connects directly to standard European or North American industrial mains without an external line filter for most installations. Built-in Safe Torque Off (STO) meets SIL 3 / PL e, eliminating the need for a separate safety relay in many guarding circuits — the drive itself breaks torque when the safety signal drops. Fieldbus is integrated as USS or MODBUS RTU on the same terminal block, so no option card is required for basic PLC communication. The I/O complement — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers start/stop, speed reference, and status feedback for a standalone machine cell.","metaTitle":"Siemens 6SL3210-1KE21-3UB0 SINAMICS G120C Drive, 5.5 kW","metaDescription":"Siemens SINAMICS G120C drive, 5.5 kW, 150% overload for 3 s, 380-480 VAC, IP20, Safe-Torque-Off, USS/MODBUS RTU.
