3S Antriebe smart actuator 300D

The 3S 300 D is a compact, smart actuator for underground valve automation in drinking water, gas, and industrial networks. It is IP68-rated, maintenance-free, and available with mains power (24–230V AC/DC) or a high-capacity battery pack. Optional 2G/3G connectivity enables remote access. Communication options include Modbus RTU, Profibus DP, or x-active for direct SCADA integration. The actuator is always manually operable with a standard valve key, regardless of power or communication status.
