Schneider Electric (Barber Colman) 2341-502 Controller

The Schneider Electric (Barber Colman) 2341-502 Receiver Controller is a high-performance pneumatic receiver controller specifically engineered for reverse acting high limit applications. Designed for stability and responsiveness in complex HVACR systems, this unit features a linear nozzle and flapper relay mechanism that ensures precise environmental management without setpoint drift. It operates at a normal main air pressure of 20-22 psig, maintaining an exceptionally low air consumption of 0.021 SCFM and a capacity of 8 SCFH. This pneumodular controller allows tech-level adjustments to throttling range (2% to 40%) and reset authority (10% to 300%) via slide-type interfaces, requiring no special tools for field calibration. Built for surface mounting, the 2341-502 integrates seamlessly with remote pneumatic transmitters to provide proportional control of temperature, humidity, and pressure. Its robust dual-input architecture supports primary and secondary (reset) signals, ensuring the high-accuracy reversing relay functionality required by seasoned contractors for critical high-pressure limit scenarios.

• Stable High Limit Control: Specifically calibrated for reverse acting logic to prevent setpoint drift in mission-critical high-limit loops.
• Superior Efficiency: Minimal air consumption of 0.021 SCFM optimizes compressor run-time and reduces system-wide energy demand.
• No-Tool Calibration: Features slide-type adjustments for throttling range and authority, streamlining field setup for HVAC contractors.
• Reliable Pneumodular Design: Compact footprint with five barbed connections for standard 1/4 inch O.D. plastic tubing ensures fast and secure installation.
• Multi-Variable Compatibility: Works with remote transmitters to regulate temperature, relative humidity, or differential pressure.

What is the primary application for the 2341-502?
This model is specifically designed as a high-limit controller for systems where a reverse acting output is required to manage pneumatic actuators based on primary and reset inputs.

Can I adjust the setpoint in the field?
Yes, the Schneider Electric 2341-502 features a graduated dial with 0.25 psi divisions for precise setpoint calibration and easy-to-use slide adjustments for gain and authority.

What air pressure is required for operation?
The unit is built for a 20-22 psig normal main air pressure, with a maximum operating pressure limit of 30 psig to ensure hardware longevity.
