Description
The Schneider Electric Barber Colman 2341-502 RA Pneumodular Receiver Controller is a pneumatic control device used in a variety of HVAC systems, particularly those that use pneumatic controls to regulate temperature. It works by sensing the desired temperature set point, which is represented by a compressed air pressure signal that is usually between 3 and 15 psi. The controller then converts this signal into a proportionate air pressure output, which is transmitted to actuators—like dampers or valves—that modify the system’s water or airflow to maintain the appropriate temperature. Converting the received signal into a proportional output provides accurate control of the temperature and guarantees that the system effectively maintains its desired temperature.
