The Honeywell RP471A1002 is a pneumatic four-port, snap-acting relay used in industrial and HVAC automation systems to convert a proportional air pressure change from a controller into a positive (two-position) pressure change. Technical Specifications According to data sheets from Honeywell and industrial suppliers like Grainger and SupplyHouse, this relay features: Operating Pressure: Normal range of 0 to 18 psi, with a maximum safe operating pressure of 30 psi. Setpoint Range: Field-adjustable between 3 to 15 psi. Switching Differential: Fixed at 1 psi, though some sources note actual operation can be between 0.3 to 0.4 psi. Air Connections: Features sharp barb connections for 5/32 inch (4 mm) O.D. plastic tubing. Construction: Molded plastic housing with neoprene diaphragms and stainless steel levers. Ambient Limits: Operating temperature range from 0°F to 140°F (-18°C to 60°C) and humidity range of 5 to 95% RH. Key Applications Pressure Conversion: Converts modulating pilot signals to two-position (on/off) outputs for pneumatic valves or damper operators. Diverting: Can be used to divert a single supply line to one of two different branches. Signal Selection: Functions as a selector to transmit the higher or lower of two input signals.
