The fully redundant DA 30-HT-D has been developed for applications with the highest reliability demands. The redundant – two channel – design of the actuator allows continuous operation even if one of the two channels has failed. All major components such as the electric motors, control and communication electronics, and power supply are available twice (redundant). The position sensor features a three channel design (for 2 out of 3 voting). Additionally, there are several sensors integrated to provide diagnostic information such as current consumption, supply voltage levels and temperature readings. All major components of the actuator are continuously diagnosed by the microcontrollers of the actuator and its health status can be read via the redundant RS485.

DA 22-BLDC Brushless Actuator To guarantee maximum safety and reliability, its brushless motor and contactless, wear-free position sensing system makes the DA 22 BLDC immune to wear, vibrations and shock loads. It has especially been designed for usage in harsh environments and for safety-critical applications that require an actuator with high endurance. The conductive aluminum case and the shielded connection cable are reducing the susceptibility to any kind to EMI/RFI noise to the absolute minimum.

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.

The DA 15‐N is our smallest and lightest full brushless actuator. Its brushless motor and contactless, wear-free position sensing system makes the DA 15‐N immune to wear, vibrations and shock loads. It has especially been designed for usage in harsh environments and for safety-critical applications that require an actuator with high endurance. The conductive aluminum case and the shielded connection cable are reducing the susceptibility to any kind to EMI/RFI noise to the absolute minimum. The servo features position, temperature and current feedback as a standard and is fully programmable.
