24-32 Volts

The well proven DA 30 is now accompanied by a High Torque version, offering an extreme high continuous torque level.

To guarantee maximum safety and reliability, our DA 30 features a brushless motor and a contactless wear free position sensor. This means maximum service life with the greatest‐possible power delivery and its design prevents electromagnetic emissions (EMI) caused by brush sparking. The housing made of saltwater‐resistant aluminum is
HART‐coat treated, meets the IP‐67 standard for water and dust sealing and provides an integrated Sub‐D connector (MIL spec. circular connector or cable gland on request). Brackets integrated in the housing for horizontal and vertical assembly. 8‐fold, ball‐bearing supported, steel gear train, drive shaft with ANSI multi‐tooth. The DA 30 series can be equipped with a standard PWM input (Pulse Width Modulation) that has two different interfaces: a differential, galvanic isolated interface (Opto‐Coupler) and a single‐ended interface with CMOS levels that is also used to program the servo parameters. It includes analog position feedback to detect the drive shaft position. A differential RS‐422 PWM interface can be chosen instead of the opto‐coupled interface. The DA 30 with digital serial command interface (RS‐485) receives its commands via a CRC secured protocol. It can return not only the shaft position in digital format, but also several diagnostic data such as the level of the supply voltage, current consumption and the temperature of the motor and electronics in digital form (optionally also the humidity within the actuator case). These kind of diagnostic capabilities help to determine the health state of the actuators before, during and after deployment.


  • RS-485  compatible, asynchronous serial command interface.
  • Customized commands can be implemented on request. 
  • Redundant RS-485 interface with redundant power supply,
  • RS-422  level compatible, differential PWM interface instead of the opto-coupler PWM interface. 
  • Humidity sensor (only in for RS-485 interface versions).
