Volume Booster/Pressure Selector
Relays
Model Chart
The volume booster relay is a proportioning device
designed for use in pneumatic control systems where
the application requires amplifying the volume of
control air to final control devices. System
transmission lag is minimized by using this relay in
conjunction with a proportional controller operating
several diaphragm valves or damper actuators. This
device may also be used as a low pressure selector
when the application requires the comparison,
selection and transmission of the lower of two
proportional input signals.
The high pressure selector relay is a device designed
for use in pneumatic control systems where the
application requires the comparison, selection, and
transmission of the higher of two proportional input
signals.
Features:
• Both models have barbed fittings.
R532-H
• Two-input high pressure selector; no adjustments.
• All ports clearly labeled.
• Not for use with “restricted” signals (use R432-2).
• TAC PNEUMODULAR: Mounts on MCS-Socket or K502
Mounting Bracket. Due to light weight, may be mounted
“in-line”, supported by tubing.
R532-L
• 1:1 booster relay with adjustable bias.
• May be used as low pressure selector (using ports S-1 and M).
• Using S-1 and S-2 inputs (and main air supply at M) may be
used as summation (adding) relay.
• All ports clearly labeled. Ports align with MCS-S terminals.
• TAC PNEUMODULAR: Mounts on MCS-Socket or K502
Mounting Bracket.

CAUTION: Do not use signals from a low volume signal source such as transmitters, one pipe thermostats, or R77 Series controllers. Use R432-2 for
these applications.
