The Siemens 6DR5522-.....-.... is a SIPART PS2 smart electropneumatic positioner with PROFIBUS PA communication, built for Ex and non-Ex environments. It is double-acting, housed in a stainless steel enclosure without a window, and designed for both pneumatic linear and part-turn actuators. This unit is classified as Product Class C — manufactured and produced to order, which means it is not a stocked shelf item. Sourcing it requires a purchase order against an RFQ; lead time depends on the current production queue.
RoHS compliance is confirmed effective 31 December 2016, and REACH candidate-list information is available for downstream documentation needs.
As a Product Class C item, the positioner is built to order. The order code covers the PROFIBUS PA variant with double-acting output and stainless steel enclosure — confirm the actuator interface and stroke range with your application before placing the RFQ. The group code R3P2 and product group 4759 are internal Siemens classifications used for catalog and export control routing. They do not affect physical fit or function.
