Schneider Electric R432 Series (2372 Series) High Pressure Selector Relay and Low Pressure Selector or Booster Relay

High Pressure Selector Relay and Low Pressure Selector or Booster Relay
R432 Series (2372 Series)

The pressure selector relays are designed for use in pneumatic control systems where the application requires the comparison, selection, and transmission of the higher or lower of two proportional signals. R432-11 can also be used as a booster relay.

• Relays are non-adjustable.
• Precise repeatability characteristics.
• Small size and light weight allow these relays to be mounted “in-line”, supported by the pneumatic tubing.
• R432-2 HP Selector may be used with “restricted” pneumatic signals down to 0.5 SCFH airflow.
• R432-11 may be used as Booster Relay or LP Selector
