Schneider Electric (Barber Colman) 2341-521 Controller

The Schneider Electric 2341-521 is a precision-engineered receiver controller designed for low limit application within pneumatic control systems. Operating as a direct acting pneumatic controller, this unit maintains system stability by modulating output pressure in response to input signals from remote sensors. It is configured for a 20-22 psig normal main air pressure and features an exceptionally low 0.021 SCFM air consumption, ensuring efficient operation across complex HVACR networks. As the industry-standard direct replacement for 2341-001, it mounts securely on a P541-BASE, making it a reliable drop-in solution for aging Barber Colman infrastructure. With an 8 SCFH air flow capacity, it manages pneumatic field devices with the accuracy required for critical environmental control. This unit is essential for technicians managing HVAC pneumatic controls where proportional control and limit protection are mandatory for system longevity and performance.

Key Benefits

• Seamless Retrofit: Functions as the verified 2341-001 replacement, eliminating the need for extensive repiping or mounting modifications.
• Efficient Air Management: Low consumption rates reduce the load on the pneumatic air compressor and minimize system-wide pressure drops.
• Robust Mounting: Pre-mounted on a P541-BASE to ensure secure installation and stable pneumatic signal transmission.
• Precise Low Limit Control: Specifically calibrated for low limit application to prevent coil freeze-up or excessive discharge temperatures.

Common Questions

Is the 2341-521 compatible with older Barber Colman sensors?
Yes, this controller is designed to interface with standard Barber Colman pneumatic sensors and transducers typically found in legacy systems.

What is the action of this controller?
This is a direct acting unit, meaning an increase in the sensed variable results in an increase in the output pressure to the controlled device.

What is the primary difference between the 521 and the discontinued 001 model?
The 2341-521 features modernized internal components for improved reliability while maintaining the exact physical footprint and operating specifications of the 2341-001.
