The Siemens 6DR5013-.....-.... is a SIPART PS2 smart electropneumatic positioner accepting a 4-20mA control signal. It is built for single-acting actuators — pneumatic linear or part-turn — and uses a non-contacting, wear-free position detection system (NCS). The aluminum enclosure carries both Ex and non-Ex approvals, so it fits hazardous-area valve assemblies as well as general-purpose plant air.
What the key ratings mean for fit
The 4-20mA analog input is the standard loop for DCS/PLC control — no HART protocol mentioned here, so treat this as a straight 4-20mA positioner. Single-acting means it drives a spring-return actuator (one pneumatic output, spring to fail). The non-contacting NCS sensor eliminates mechanical wear and linkage backlash, which is the main drift source on older cam-follower positioners. Aluminum enclosure is lighter than stainless but still corrosion-resistant for most process environments; if you need washdown or aggressive chemical exposure, confirm the enclosure rating against your area classification.
Where it is used
SIPART PS2 positioners are the standard fit for pneumatic control valves in process plants — refineries, chemical units, power generation, water treatment. The 4-20mA loop interface ties directly into any analog output card on a DCS or PLC. Single-acting covers the majority of spring-return valve actuators; if your valve is double-acting, you need a different variant.
