General

ADM 322S: Rotary actuator with positioner for best operating convenience, precision activation and high energy efficiency with minimal operating noise.

This actuator is used to operate control units like control valves, butterfly valves etc. in HVAC installations and must only be used for these purposes. The actuator can be used as a 2-point (OPEN/CLOSE) or 3-point actuator (OPEN/STOP/CLOSE). The running time of the actuator can be set with the S1 switches according to the respective requirements.

Features

• For operating control units such as control valves, butterfly valves etc.
• For controllers with a continuous output
• 15 Nm nominal torque and holding torque
• ADM322SF122: Synchronous motor with electronic control unit and load-dependent cut-off
• ADM322SF152: Brushless DC motor with SUT (SAUTER Universal Technology) electronic control unit and electronic, load-dependent cut-off
• Low operating noise
• Automatic recognition of applied control signal
• With the built-in absolute distance measurement system, the position is always maintained in the case of power failure
• The direction of operation, running time and control signal (voltage/current) can be adjusted via coding switches
• High-speed variant ADM322SF152 with 30 s or 60 s for angle of rotation 90°
• Gear unit can be disengaged for manual adjustment •Easy re-initialisation using a coding switch
• Electrical parallel operation of up to five actuators possible
• Numerous adapters enable the unit to be fitted onto defined non-SAUTER control valves
• ADM322SF152: Integrated forced operation can be set via coding switches (with selectable direction of operation)
• Maintenance-free gearbox made of plastic and steel, and gearbox base-plates made of steel
• Mounting columns made of aluminium
