Description
The Schneider Electric (Barber Colman) 2372-352 is a pneumatic pressure selector relay engineered for building automation and HVAC control systems that require intelligent signal selection. This relay continuously monitors two separate pneumatic input signals and automatically transmits the higher of the two to the output, making it ideal for override control, high-limit selection, and multi-zone pneumatic sequencing applications.
Key Features
- Transmits the higher of two pneumatic input signals for reliable high-signal selection logic
- 20 PSIG main air operating pressure for compatibility with standard pneumatic control systems
- 29 SCIM (Standard Cubic Inches per Minute) capacity at the main port for adequate flow delivery
- 1.5 SCIM capacity at the signal port for precise signal handling
- Nipple fittings sized for 1/4″ O.D. tubing — compatible with standard pneumatic control tubing
- Compact, durable construction suited for panel or field mounting in commercial HVAC applications
