PRODUCT DESCRIPTION
SIEMENS 7NG0320-0BA00-0AA0-ZC20 - Electro-Pneumatic Positioner
This device is a SIEMENS SIPART PS2 electro-pneumatic positioner, designed for precise control of linear and part-turn pneumatic actuators. It converts an analog 4-20 mA input signal into a proportional pneumatic output pressure, ensuring accurate valve or damper positioning. The unit integrates a robust position sensor and includes two inductive limit switches for feedback on actuator end positions, making it suitable for process control applications requiring reliable and repeatable positioning.
