                                      1:1 Booster Relay

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.                                               R-2080 1:1 Booster Relay

connection. When the output
pressure is equal to the pilot
pressure, equilibrium is reached
in the two chambers and the
output pressure will be
maintained until the pilot
pressure changes. If the pilot
pressure decreases, an exhaust
port in the output chamber will
be opened to exhaust the output
air until both chambers again
have equal pressure.

Installation
R-2080 1:1 Booster Relays are
intended primarily for in-line
mounting with provisions for a
panel mounting bracket. Supply,
output and pilot connections are
marked on the instrument and
are designed to accept 5/32 in.
