The Siemens thermal drive actuator is a versatile device designed for control of thermal drive actuators. The device is connected to the bus via a bus terminal block and is powered by the bus voltage. With its ability to save and restore switching status values on bus voltage failure and recovery, as well as its configurable actions and status reporting, the thermal drive actuator offers a reliable and efficient solution for control systems. Resetting the device to ex-factory settings is simple with the programming button. The device comes with various addressing modes and offers options for configuring the valve control, cycle time, pulse width modulation, and more.
