The Siemens 6DR5610-.....-.... is a SIPART PS2 smart electropneumatic positioner with FOUNDATION Fieldbus communication, rated for Ex and non-Ex environments. It is single-acting and housed in a polycarbonate enclosure, designed for pneumatic linear and part-turn actuators.
Note the product class C designation: this unit is manufactured to order and cannot be reused or returned for credit. Plan your BOM quantities accordingly — no overstock cushion on this line.
What the key specs mean for fit
The FOUNDATION Fieldbus interface means this positioner talks directly to a DCS or host system over the standard H1 bus, no analog I/O card needed. If your plant runs Profibus PA or HART, this is not the right variant — stick with the SIPART PS2 family but pick the correct protocol module.
Mounts directly to linear actuators per IEC 60534-6 or to part-turn actuators via the NAMUR bracket. The FOUNDATION Fieldbus connection is a standard 2-wire twisted pair with polarity-insensitive termination; bus power is supplied by the segment coupler. Ensure the bus segment has enough power budget for the positioner's draw — typical SIPART PS2 consumption is under 12 mA on the bus.
