Schneider Electric (Barber Colman) 2341-501 Receiver Controller, Direct Acting, Low Limit

Description

The Schneider Electric (Barber Colman) 2341-501 is a pneumatic receiver controller engineered for low limit applications in commercial HVAC and building automation systems. Designed with direct acting control logic, this controller receives a pneumatic input signal and modulates its output to maintain precise control of temperature, pressure, or other process variables at their lowest allowable setpoint — protecting equipment and occupants from under-limit conditions.

Key Features

• Direct acting control action for reliable low limit protection
• Designed for low limit application use in commercial HVAC systems
• Normal main air pressure range: 20–22 psig
• Ultra-low air consumption: 0.021 SCFM (standard cubic feet per minute)
• Air flow consumption: 8 SCFH (standard cubic feet per hour)
• Compatible with standard pneumatic control systems
• Compact, durable construction suited for demanding commercial environments

Specifications

• SKU: 2341-501
• Brand: Schneider Electric (Barber Colman)

Application

The 2341-501 receiver controller is ideal for use in air handling units, mixed air control systems, and other HVAC applications where low limit protection is critical. It works within pneumatic control loops to override standard control signals when a process variable drops below the established minimum threshold, preventing coil freeze-up, equipment damage, or unsafe conditions. Its minimal air consumption makes it an efficient choice for large-scale pneumatic control installations.
