Description

ABB Rotary Actuator PME120-AI/-AN (Contrac)

ABB Rotary Actuator

Every industrial industry uses actuators. They are in charge of adjusting the positions of valves and other components in the field of

process automation.to regulate the movement of matter, mass, and energy. The preference for actuators as a “knowledgeable field “is currently regarded as a part of the state. the art. In recent years,there has been a rise in calls for the inclusion of functions with indices, in addition to bus connectivity systems and device and process visualization data.CONTRAC has been developed to satisfy these demands. CONTRAC, a composite term based on the words control and actuator, is an “intelligent”
and compact actuator.

Operating principles:-

The actuator continuously responds to a setpoint signal. The motor is constantly under voltage (operating mode S9 – 100 % stall proof according to IEC 60034-1 / EN 60034-1) and gently increases or reduces the torque on the electronic unit in proportion to the ΔY signal (the difference between the Y
setpoint and the Y position signal – see Figure 4). The actuator is not subject to any temperature derating, there are no restrictions, even at the maximum permissible ambient temperature. Where a state of balance exists, the actuator force and process force are equivalent and the actuator will keep the control element in the required position. If such a “state of balance” applies, the ΔY value will be in the proportional area of the torque/force characteristic curve(see Figure 4).
