3S Antriebe smart actuator 500D

The 3S 500 D is an intelligent, maintenance-free actuator designed for underground valve automation in modern drinking water, gas, and industrial networks. Available with either mains power or a powerful battery module, it supports communication via Modbus RTU, Profibus DP, or x-active for seamless SCADA integration. With an IP68-certified housing and flexible installation options, the 3S 500 D is ideal for environments ranging from flood-prone areas to remote network sections. Manual operation with a standard valve key is always possible, ensuring operational security in all conditions.
