Schneider Electric (Barber Colman) 2341-501 Receiver Controller

The Schneider Electric (Barber Colman) 2341-501 Receiver Controller is a high-performance direct acting pneumatic component engineered for precise proportional control in commercial HVACR systems. Specifically designed for low limit applications, this pneumatic receiver controller utilizes a nozzle and flapper pilot mechanism with pneumatic feedback to ensure exceptional linearity and stability across its entire operating range. It interfaces seamlessly with remote pneumatic transmitters to regulate variables such as temperature, humidity, and static pressure.

Operating with a normal main air pressure of 20-22 psig, the 2341-501 is optimized for efficiency, featuring a maximum air consumption of only 0.021 SCFM at constant output. The unit supports dual-input configurations and provides an air flow capacity of 8 SCFH, making it an ideal choice for contractors maintaining pneumodular control sequences. Its robust construction consists of glass-filled nylon and stainless steel, ensuring durability in demanding mechanical rooms while preventing setpoint drift through its integrated limit valve.

• Precise Low Limit Control: Specifically calibrated as a direct acting low limit controller to prevent system setpoint drift in critical pneumatic loops.
• No-Tool Calibration: Features slide-type throttling range and authority adjustments for efficient field setup without specialized hand tools.
• High Stability: The industrial-grade nozzle-and-flapper design provides superior repeatability and stability compared to standard residential relays.
• Versatile Application: Compatible with 1/4 inch O.D. plastic tubing via five secure barbed connections for standardized system integration.
• Low Air Consumption: Maximizes compressor life with a minimal 0.021 SCFM draw during steady-state operation.

Is the 2341-501 suitable for high-limit applications?
No, this specific model is a direct acting unit configured for low limit applications. For high-limit requirements, the 2341-502 reverse-acting model is typically utilized.

What is the maximum air pressure this controller can handle?
While the normal operating range is 20-22 psig, the unit is rated for a maximum main air pressure of 30 psig.

Does this unit require an external relay for proportional-plus-integral control?
Yes, for P+I control functionality, this receiver controller is intended to be used in conjunction with an R500 (2351-001) integral relay.
