Schneider Electric (Barber Colman) 2360-501 Relay

The Schneider Electric (Barber Colman) 2360-501 is a high-performance pneumatic reversing relay engineered for precise proportional control in commercial HVAC systems. This pneumodular reversing relay is a technical necessity when an application requires an output signal to move in the opposite direction of the input signal pressure. As a direct replacement for AK-40613, it ensures seamless integration into existing legacy pneumatic loops. The unit is factory-calibrated to decrease branch line pressure from 16 to 0 psig as the input signal increases, effectively minimizing system lag by amplifying the air volume available for dampers or valves.

Constructed from durable glass-filled nylon, the Schneider Electric 2360-501 features a field-adjustable ±10 psig bias adjustment, allowing technicians to fine-tune the crossover point between 2 and 15 psig to align with specific sequencing requirements. Operating with a 20 psig normal main air pressure, it maintains a massive 230 SCIM air flow capacity while keeping air consumption at a low 29 SCIM. Designed for flexible installation, the relay includes barbed nipples for 1/4" O.D. or 5/32" I.D. tubing and comes standard with a mounting strap and adhesive-backed base for surface or socket-mounted applications.

• Precise Signal Inversion: Converts a direct-acting signal into a reverse-acting output to manage complex sequencing logic.
• Modular Compatibility: Designed for 22-120 manifold sockets but adaptable for surface mounting with the included strap and adhesive base.
• Reduced System Lag: High air capacity (8 SCFH) ensures rapid response times for final control elements.
• Legacy Support: Serves as the official AK-40613 replacement, maintaining compatibility across Barber Colman and Schneider Electric systems.
• Simplified Maintenance: Ports are clearly marked (Main, Branch, and Input Signal) to streamline troubleshooting and piping.

How do I adjust the bias on the 2360-501?
Use a 5/64" hex wrench to adjust the bias. Rotating the adjustment screw allows you to advance or retard the output signal by ±10 psig depending on the specific sequencing needs of your control loop.

Can this relay be used with oily or wet control air?
No. This device requires clean, dry, and oil-free control air to prevent internal diaphragm contamination and ensure long-term reliability in the pneumatic circuit.

What is the maximum supply air pressure for this unit?
While the nominal operating pressure is 20 psig, the 2360-501 is rated for a maximum supply air pressure of 30 psig.
