The Johnson Controls R-2080-1 Booster Relay is a Johnson Controls relay for HVAC repair and replacement work. Use it when the part number R-2080-1 and the listed specifications match the equipment being serviced.
The R-2080 operates as a pneumatic repeater and volume amplifier. The pilot signal received by the R-2080 is repeated at its output at a 1:1 ratio. The pilot signal, usually from a non-relay (low volume) controller, is amplified to a large volume output signal to either improve the response time of a controlled device or to operate additional controlled devices. The R-2080 develops an accurate, direct acting 1:1 relationship between pilot and output pressures over its operating range.
