PME120-AI / PME120-AN (CONTRAC) ELECTRICAL ROTARY ACTUATOR | DS/PME120-EN REV. D Change from one to two columns — Brief description Compact actuator for the operation of final control elements with rotary movement such as valve flaps, ball valves, etc. The torque is transferred via a lever-type actuator or the actuator is directly coupled to the shaft of the final control element. The actuator is controlled using a Contrac electronic unit. This electronic unit serves as the interface between the actuator and the control system. During continuous positioning, the electronic unit varies the...

PME120-AI / PME120-AN (CONTRAC) ELECTRICAL ROTARY ACTUATOR | DS/PME120-EN REV. D — … Brief description The handwheel offers an optimum level of performance between handwheel forces and rotational speed, owing to the design principle of the differential gearing. Furthermore, the gear train is not interrupted, even though it is possible to adjust the handwheel at any time. This ensures maximum operational reliability. The 3-phase asynchronous motor is equipped with a spring-loaded brake. The brake is energized in automatic mode. In the case of a fault or failure of the supply voltage, the...

PME120-AI / PME120-AN (CONTRAC) ELECTRICAL ROTARY ACTUATOR | DS/PME120-EN REV. D Rapid traverse mode Ambient conditions The actuator is operated exactly in the same operating mode as in the analog control mode. On activation of digital inputs 2 or 3, the actuator moves at twice the rated operating speed and half the torque in the corresponding direction. Just before the end position is reached, the actuator travel speed is automatically switched back to the set speed, at which the remaining distance is covered. Temperature Different temperature versions are available, depending on the...

PME120-AI / PME120-AN (CONTRAC) ELECTRICAL ROTARY ACTUATOR | DS/PME120-EN REV. D — Communication The PROFIBUS DP®, PROFIBUS DP®/V1 or HART® communication protocols are available for digital communication. PROFIBUS® PROFIBUS DP® is an international, open field bus protocol which has been standardized in the field bus standard EN 50170. On a cyclic basis, the master reads the input information from the slaves and writes the output information to the slaves. In addition to this cyclic data transfer of the process representation (e. g. setpoint and actual value), Profibus DP also provides...
