The Siemens 6DR5615-.....-.... is a SIPART PS2 smart electropneumatic positioner with FOUNDATION Fieldbus communication, in a flameproof (Ex d) aluminum enclosure. It is single-acting and designed for pneumatic linear and part-turn actuators.
RoHS compliance is confirmed since 31-12-16, and REACH candidate-list information is available on request.
The FOUNDATION Fieldbus interface means this positioner integrates directly into a FF segment without an external gateway — the H1 bus powers the electronics and carries the cyclic position setpoint. The Ex d (flameproof) enclosure is rated for Zone 1 gas groups, so it can be mounted directly on the actuator in hazardous areas without an additional isolation barrier. Single-acting design means it drives one pneumatic chamber (spring-return actuators), not double-acting. For double-acting actuators, a double-acting variant from the same SIPART PS2 family would be needed.
