The Siemens 6DR5510-.....-.... is a SIPART PS2 smart electropneumatic positioner communicating over PROFIBUS PA, built for single-acting pneumatic linear and part-turn actuators. The polycarbonate enclosure is rated for Ex/nEx environments, so it can be mounted directly in hazardous-area valve assemblies without an external purge or isolation cabinet — a common requirement on process skids where the positioner shares the zone with the actuator.
Compliance and documentation
The part is REACH candidate-list notified and carries an AL: N / ECCN: N export classification, which simplifies cross-border procurement — no special license required for most destinations. For quality-doc control, the manufacturer provides a declaration of conformity covering the PROFIBUS PA interface and ATEX/IECEx certification; the polycarbonate enclosure material is listed in the REACH Article 33 duty-to-inform statement.
