Johnson R-2080-1 Relay Booster Pneumatic

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.
