Pneumatic Controller Direct Acting 40-130 Degrees Fahrenheit

High capacity, single/dual input pneumatic controller, used in conjunction with remote sensors, to provide proportional (P) or proportional plus integral (P+I) control of temperature, humidity, pressure, or dewpoint for heating and air conditioning.

• Proportional plus integral control option minimizes offset
• Miniature diaphragm technology provides high degree of accuracy and reliability
• Direct acting models can be converted to reverse acting (RA) function in field
• Field adjustable compensation start point
• Corrosion resistant construction
• 0.07 scfm with 1 psi pressure drop at 18 psi main air supply usage
• 40 to 130 deg F temperature
• The controller is capable of operating with the MLPas low as 15 psi or as high as 23 psi, however recalibration may be required
• All RP920s can be converted to reverse acting in the field
• 5 to 95% RH operating humidity range
• Combination 5/32 in by 1/4 in barb air connection
• 3 to 15 psi input signal , 3 to 13 psi output signal, 1/2 psi output signal maximum is mainline pressure
• 18 psi MLP and 8.5 psi BLP: 0.021 scfm capacity
