K-10

The Westlock K-10 electro-pneumatic positioner accepts variable instrumentation signals (between four and 20 milliamps) from a PLC, DCS or set point controller, and regulates the 80-psi air supply to and from the actuator. This process regulates the actuator position within its quadrant for precise modulation.

Features and Benefits

• Simple calibration of positioner with AutoCal
  pushbuttons located inside housing
• Corrosion resistant engineered resin enclosure;
  meets NEMA 4X
• Beacon visual position indication
• Pressure gauges
• 3/4" FNPT conduit entry
• Split range capability
• Reverse acting capability
• NAMUR mount - no linkage options

Specifications

• Input current: 4 to 20 mA (analog)
