SEVEN actuators

HiMod

Suitable for every process

High accuracy actuators for continuous modulation.

Rotary actuators 2SA78.. 10 - 2800 Nm

Part-turn gearboxes 2SP78.. 125 - 1305 Nm

Standard design 2SA78

• duty classification: continuous modulating duty, class D according to EN 15714-2
• protection class IP68 acc. to DIN EN 60529
• corrosivity category C5 acc. to EN 15714-2
• electronic motor protection, automatic phase sequence correction
• start-up current lower than rated current
• line voltage tolerance -10% / +15% in the chosen voltage range, frequency range from 40 to 70 Hz
  (full torque for voltage fluctuations between –30 % and +15 %)
• permissible ambient temperature: -20°C to +60°C (-4°F to +140°F), (lower / higher temperatures on request)
• electric connection: round plug with screw connection,
  dust and water-protected when plug withdrawn (double sealed)
• separate mounting of the electronics unit possible
• hand wheel for emergency operation (disconnected during motor operation!)
• „non-intrusive“: adjustment/parameterization without opening the actuator
• valve protection through integrated frequency converter: soft start and speed reduction in the end positions
• extremely high modulating accuracy: max. 0.1 to 0.2 % deviation from the overall travel
• continuous settable output speed within the selected speed range
  (parameterizable on the display in 2.5% increments between 12.5 - 100% n max.)
• output speeds independently adjustable for OPEN, CLOSE, Emergency OPEN and Emergency CLOSE
• tripping torques adjustable from 50% to 100% of max. output torque TC max. for OPEN and CLOSE in steps of 10%
• travel dependent cut-off continuously adjustable
• 3 reference torque curves of the valve can be stored
• local control with hermetically sealed control knob „Drive Controller“ (optionally lockable)
• operator guidance via display
• external 24 V DC supply for electronics unit possible
• external 24 V DC or 48 V DC supply of the galvanic isolated binary inputs and outputs possible
• galvanic isolation of the analog inputs and outputs
• analog actual position value 0/4 – 20mA
• analog position setpoint (positioner) 0/4 – 20 mA
• communication with COM-SIPOS via USB and Bluetooth possible
• real-time event logging
• 5 years warranty for both gear unit and motor
