RP920A1025 : Honeywell Pneumatic Controller, Single Input, Direct Acting, with Remote Control Point Adjustment

Honeywell RP920A1025 High capacity, single 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.

Features:
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.

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.
