It is single-acting, housed in a stainless steel enclosure rated flameproof (Ex d), and designed for pneumatic linear and part-turn actuators. Product class C means this is manufactured to order — not a stocked shelf item. Lead time is quoted against an RFQ; no returns or reuse after the order is cut. RoHS compliant since 31-12-16, with REACH candidate-list documentation available. Export controls are AL: N / ECCN: N, so no special licensing for cross-border shipment. ## Integration notes PROFIBUS PA interface means it drops onto a segment with other PA devices — no analog I/O card needed. Single-acting design suits spring-return actuators; for double-acting you'd need a different variant in the PS2 family. The Ex d flameproof enclosure allows mounting in Zone 1 gas groups without an external purge system. SST body handles washdown and corrosive atmospheres better than aluminum.","metaTitle":"Siemens 6DR5516-.....-.... SIPART PS2 Positioner, PROFIBUS P","metaDescription":"Siemens 6DR5516-.....-....
