Overview
The National Controls DNC-T2020-B10 is an industrial-grade program control board designed for automated dust collector pulse-cleaning systems. Operating on 105-135VAC input at 50-60Hz line frequency, this unit manages sequential output timing and high-pressure switch logic for baghouse dust collector controls. Though discontinued by the manufacturer, the DNC-T2020-B10 remains a reliable component in existing dust collection installations where precise timing control is essential for filter cleaning cycles.
Key Features
- Digital timing circuitry with stable operation across -40°C to 65°C temperature range
