Auxiliary switch ASC10.51 switches on or off when a certain position is reached. The
switching point can lie between 0 to 100%.
Potentiometer ASZ7.5/.. (1000 Ω, 200 Ω, 135 Ω) delivers an ohmic value to the
controller giving the exact position of the actuator (continuous position feedback).
Stem heating element ASZ6.6 prevents the formation of ice on the stem when the
medium temperature drops below 32°F (0°C). It is suited for universal use with valves
having a stem or spindle diameter of 10 or 14 mm.
Weather Shield ASK39.1 protects the actuator when installed outdoors. Provides NEMA
3R protection.
