Overview
The Itoh CB-002N is a compact brushless DC motor driver card manufactured by Itoh Denki for control of 24VDC brushless motors. Originally sold as part of the Power Moller series for industrial automation and conveyor applications, this driver board delivers dependable commutation and speed regulation for maintenance, replacement, and retrofit projects. Although discontinued by the manufacturer, the CB-002N remains sought-after for troubleshooting legacy systems and supporting continued operation of equipment where original spares are unavailable.
Key Features
- Brushless DC motor commutation for 24VDC operation
- Thermal protection and dynamic brake control built into the card
- Variable speed control from 25% to 100% via onboard or remote potentiometer
- DIP switch selection for internal or external speed control and CW/CCW direction
- Compact form factor with integrated connectors for straightforward installation
- Proven reliability in industrial conveyor, fan, and pump applications
