24 to 30 volts
The fully redundant DA 26-D actuator for applications with 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 interface.
