Electrothermal actuator “Aktor T ST” – OVENTROP

Electrothermal actuator “Aktor T ST” “L NC”, 24 V, closed with current “off”, 0 – 10 V With automatic recognition of neutral point and valve travel. The actuator (0 – 10 V) can be used in centralised building control systems in combination with the electronic room thermostat, item no. 1152151/53, or with a central controller. Plug-in connecting cable 1 m. With First-Open function and stroke index. Easy plug-in connection with valve adapter. Due to their construction, the electrothermal actuators are secured against overvoltage which could occur when switching on neon tubes. A varistor is thus not necessary.
