Honeywell RP920A1025 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 dewpoint 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.
Remote bulb sensor no
Number of Sensor Inputs single
