Siemens 6DR5120-0NG00-0AA0 PS2 Smart Positioner for Process Automation

Product Description

The Siemens 6DR5120-0NG00-0AA0 SIPART PS2 is a smart electropneumatic positioner designed for precise control of pneumatic linear and rotary actuators.
It operates on a 2-wire, 4…20 mA control signal and supports single-action actuators for standard industrial environments.
The polycarbonate enclosure provides durability while maintaining a lightweight profile, allowing easy installation in compact spaces.
Moreover, the SIPART PS2 series incorporates self-calibration and diagnostic functions, ensuring accurate valve positioning with minimal maintenance.
Fail-safe depressurization protects the actuator in case of auxiliary power failure, enhancing operational safety in process automation applications.
Its intelligent design makes it a cost-effective solution for industries requiring reliable control of flow, pressure, temperature, or level.
