The 6DR5513-.....-.... is a Siemens SIPART PS2 smart electropneumatic positioner with PROFIBUS PA communication, rated for Ex and non-Ex environments. It is single-acting, housed in an aluminum enclosure, and designed for pneumatic linear and part-turn actuators.
Sourcing and compliance
This part carries a product class of C, meaning it is manufactured or produced to order and cannot be reused or returned against credit. Plan your order lead time accordingly — it is not a stocked shelf item. RoHS compliance is confirmed effective 31 December 2016, and REACH candidate-list information is available on request. Export control classifications are AL: N / ECCN: N, so no special licensing is needed for standard shipments.
What the key ratings mean for fit
The PROFIBUS PA interface means this positioner connects directly to a segment coupler on a process automation bus — no analog I/O card needed. The single-acting design suits spring-return actuators; for double-acting units you would need the dual-acting variant in the same family. The aluminum enclosure handles the heat and grit of a cement plant or refinery control room better than a plastic housing — it conducts heat away from the electronics and stands up to washdown chemicals. Rated for Ex zones, so it can mount in hazardous areas without an external purge.
