6DR5013 SIPART PS2 smart electropneumatic positioner for pneumatic linear and part-turn actuators; 2-wire; 4…20mA; single action; Enclosure Aluminium
Valve Positioner – SIPART PS2
The SIPART PS2 electropneumatic positioners are used to control the process valve or damper position of pneumatic linear or part-turn actuators or via positioning cylinder according to the setpoint specification. A digital input can trigger holding of the position or approach of the safety setting of the process valve

Benefits
SIPART PS2 positioners offer decisive advantages:
- Simple mounting and automatic commissioning
- Simple operation and configuration of the device using 3 buttons and one 2-line local display or via SIMATIC PDM
- Very high control performance
- Negligible air consumption in stationary operation
- “Tight closing” function ensures maximum positioning pressure on the process valve seat
- “Fast Open/Fast Close” function for defined approach of the end position with fast reaction to new setpoint specifications
- “Fail in Place” function:
Maintain current position on failure of electrical and/or pneumatic auxiliary power - Numerous functions can be activated by simple configuring (e.g. characteristic curves and limits)
- One device variant for linear and part-turn actuators
- Insensitive to vibrations due to few moving parts and optionally with wear-free position detection
- External non-contacting sensor as option for extreme ambient conditions
- “Intelligent solenoid valve”: Solenoid valve function and diagnostics in one device
- Extensive diagnostic functions for process valve and actuator, e.g.:
- Full Stroke Test
- Multi Step Response Test
- Valve Performance Test
- Valve Signature, pressure sensor-aided
- Partial Stroke Test e.g. for safety process valves (also pressure sensor-aided) for performance and maintenance evaluation of the valve
- Can be operated with natural gas, carbon dioxide, nitrogen or noble gases
- SIL (Safety Integrity Level) 2
Application
The SIPART PS2 positioner is used worldwide on all pneumatic actuators, in all applications and industries:
- Chemical industry
- Petrochemical industry
- Oil and gas
- Water/wastewater industry
- Power supply
- Pharmaceutical industry
- Food, beverage and tobacco industries
The devices are available in variants for:
- 4 to 20 mA
- HART communication
- PROFIBUS PA communication
- FOUNDATION Fieldbus (FF) communication
- Single-and double-acting valves in various enclosure designs and various materials (polycarbonate, aluminum and stainless steel)
- Applications without explosion protection requirements
- Hazardous applications in the versions:
- Device protection with intrinsic safety (Ex i)
for use in Zone 1, 2, 21, 22 or Class I, II, III/Division 1/Groups A-G - Device dust ignition protection by enclosure (Ex t)
type of protection for use in Zone 21, 22 or Class II, III/Division 1/Groups E-G - Device protection with increased security (Ex e)
for use in Zone 2 or Class I, Division 2, Groups A-D - Device protection with flameproof enclosure (Ex d)
for use in Zone 1 or Class I, Division 1, Groups A-D
- Device protection with intrinsic safety (Ex i)
Stainless steel enclosure for extreme ambient conditions
The SIPART PS2 is available in a stainless steel enclosure for use in particularly aggressive environments (e.g. offshore operation, chlorine plants). The device functionality is not different due to the enclosure variants.
Design
- Base plate with lid with/without inspection window, depending on the variant
- Electronics with screw-type terminals:
- 4 to 20 mA
- 4 to 20 mA with HART
- PROFIBUS PA according to IEC 61158‑2, bus-supplied
- FOUNDATION Fieldbus (FF) according to IEC 61158‑2, bus-supplied
- Position feedback via potentiometer or non-contacting sensor (NCS)
- Pneumatic block
The pneumatic connections for supply air and actuating pressure are located on the right side of the enclosure. A gauge block, venting gauge block, booster, VDI3847 interface or a safety solenoid valve can be connected there as options. The SIPART PS2 positioner is fitted to the linear or part-turn actuator using an appropriate mounting kit.
Optional expansion with modules and functions
Optionally, SIPART PS2 can be expanded with the following modules and functions:
Analog Output Module (AOM)
Analog position feedback 4 to 20 mA.
Digital I/O Module (DIO) with 3 digital outputs and 1 digital input
- Signaling of two limits of the travel or angle. The two limits can be parameterized independently as maximum or minimum values.
- Output of an alarm if the setpoint position of the final control element is not reached in automatic mode or if a device/valve fault occurs.
- 2nd digital input for alarm signals or for triggering safety reactions, e.g. hold position or approach safety position.
Inductive Limit Switches (ILS)
Via the inductive switches, 2 independent limits can be set and monitored as NAMUR signal (EN 60947‑5‑6). The module also contains an integrated fault indicator (see “Digital I/O Module (DIO)”).
Mechanic Limit Switches (MLS)
2 independent limits can be monitored via the mechanical switches. The module also contains an integrated fault indicator (see “Digital I/O Module (DIO)”).
Valid for all modules described above:
- All signals are electrically isolated from one another and from the basic unit. The outputs indicate self-signaling faults. The modules are easy to retrofit.
Configuring
The SIPART PS2 positioner contains the following configurations:
- Input current range 0 to 20 mA or 4 to 20 mA
- Rising or falling characteristic curve at the setpoint input
- Positioning speed limit (setpoint ramp)
- Split-range mode: Adjustable start-of-scale and full-scale values
- Response threshold (deadband); self-adjusting or fixed
- Direction of action: Rising or falling output pressure with rising setpoint
- Limits of position range, start-of-scale/full-scale value
- Thresholds (alarms) of the process valve position: Minimum and maximum value
- Automatic tight closing stroke adjustment in accordance with the valve process characteristic curve
- Function of the digital inputs
- Function of alarm output, etc.
