Schneider Electric (Barber Colman) 2368-502 Pneumatic Relay

The Schneider Electric 2368-502 is a robust Pneumodular Electric-Pneumatic Relay designed for heavy-duty HVAC pneumatic control systems. Operating on a 110 Vac coil, this SPDT pneumatic switch provides reliable conversion between electrical signals and pneumatic pressure. When the coil is de-energized, the common (C) and normally open (NO) ports are connected; upon energizing, the connection shifts to the normally closed (NC) port. Optimized for a 20 to 25 psig main air pressure range, this relay delivers a 60 scfh air capacity with a minimal 29 scim air consumption, ensuring system efficiency. The unit features integrated barbed nipples for quick installation with 1/4" O.D. or 5/32" I.D. plastic tubing. Field technicians rely on the 2368-502 relay for its precision in sequencing pneumatic actuators and interlocking electrical equipment with air-run control loops in commercial building automation systems.

• Efficient Air Management: High 60 scfh flow rate ensures rapid response times for downstream pneumatic components.
• Direct Compatibility: Standard barbed fittings allow for seamless integration with existing pneumatic tubing without additional adapters.
• Low Parasitic Loss: Minimal 29 scim air consumption reduces the cumulative load on the control air compressor.
• Flexible Mounting: Part of the Pneumodular system, allowing for clean, organized manifold Or surface mounting in control cabinets.

How do I wire the Schneider Electric 2368-502 for fail-safe operation?
The SPDT internal switch allows for flexible logic; typically, you pipe the "Normally Open" port to your primary control device to ensure a specific state is maintained if the 110V circuit is interrupted.

Can this relay handle pressures higher than 30 psig?
While designed for standard 20-25 psig branch and main lines, exceeding the rated pressure can lead to diaphragm fatigue or seal failure; always use a pressure regulator upstream.

What is the primary cause of clicking or rapid cycling in this relay?
Rapid cycling is usually indicative of an unstable 110 Vac control signal or significant downstream air leaks that prevent the pneumatic loop from stabilizing.
