The 6DR5520-.....-.... is a Siemens SIPART PS2 smart electropneumatic positioner with PROFIBUS PA communication, double-acting output, and a polycarbonate enclosure. It is designed for pneumatic linear and part-turn actuators in process control loops. Compliance documentation covers RoHS (since 31-12-16) and REACH candidate list disclosure, which covers EU regulatory requirements for the component.
Integration notes
PROFIBUS PA interface means it drops onto a segment with other PA devices — no gateway needed if the DCS or PLC already supports PA. The double-acting output handles spring-return and double-acting actuators alike. Polycarbonate enclosure is standard for the SIPART PS2 family; it holds up in industrial environments but check the ambient temperature range against your application if the actuator is near a steam or hot-process line.
