Overview
The Barber Colman 120 Series Enclosure is a legacy analog temperature control enclosure designed for HVAC, refrigeration, and industrial process control applications. This 0-10V input control model operates on standard 120 VAC power and delivers dependable on/off or proportional control for heating and cooling loops. Discontinued by the manufacturer, this used unit remains fully functional and is suitable for retrofitting or replacing existing 120 Series controllers in operating systems.
