Pneumatic Temperature Controllers
RP920 Pneumatic Controller
Proportional, high capacity, single or 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 dew point for heating and air
conditioning systems. Replacement devices are available for
Johnson, Powers, Robertshaw, Barber-Colman, and older
Honeywell controllers.
• 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.
• Local or remote setpoint field option. Integral action cut-off provides
trouble-free automatic startup.
• Transparent cover (optional) provides protection while allowing easy
reading of settings and gages.
• Corrosion resistant construction.
Airflow Usage: 0.07 scfm (33.0 mL/s) with 1 psi (7kPa) pressure drop
at 18 psi (124 kPa) main air supply
Connections: Air: Combination 5/32 in. by 1/4 in. barb.
Input Signal: 3 to 15 psi (21 to 103 kPa)
Maximum Operating Temperature: 130 F (54 C)
Temperature Range: 40 F to 130 F (5 C to 55 C)
Humidity Ratings: 5 to 95% RH
Maximum Safe Operating Pressure: 30 psi (207 kPa)
Mainline Pressure Range: 17 to 21 psi (115 to 145 kPa)
Output Pressure Range: 3 to 13 psi, output signal maximum is
Mainline Pressure minus 1/2 psi (21 to 90 kPa, output signal maximum
is Mainline Pressure minus 7 kPa)
Maximum Safe Mainline Pressure: 30 psi (205 kPa)
Remote Bulb Sensor: no
Remote Control Point Adjustment: Ye s
Comments:
additional technical information see literature Form no. 85-0224 and 957392EF.
Comments on Pressure: The controller is capable of operating with the
MLP (Mainline pressure) as low as 15 psi (100 kPa) or as high as 23 psi
(160 kPa), however recalibration may be required.
All RP920s can be converted to reverse acting in the field. For
