Handheld IOP for SINAMICS drives — what's in the kit
The Siemens 6SL3255-0AA00-4HA0 is a handheld Intelligent Operator Panel (IOP) for the SINAMICS G120, G120P, G110M, G110D, G120D, G120C, S110, ET 200S FC, ET 200pro FC, and ET 200pro FC-2 drive families. It comes as a complete kit: the IOP itself, a handheld housing, an international power supply, four rechargeable AA batteries, a 3-meter RS232 connecting cable, and a 1-meter USB cable.
What it does on the line
This IOP gives a commissioning engineer or field-service tech a portable interface to parameterize, monitor, and diagnose the drive without a laptop. The RS232 cable reaches 3 m — enough to stand at the motor or the panel while scrolling through parameters. The USB cable handles the PC connection for firmware updates or quick parameter uploads. The rechargeable batteries mean it stays operational through a full shift on the floor.
