Overview
The Allen-Bradley 20-HIM-A3 is a PowerFlex Architecture Class human-machine interface (HIM) keypad module designed for portable and integrated drive control. The unit combines a high-contrast LCD display with a full numeric keypad, enabling technicians and engineers to configure, monitor, and troubleshoot PowerFlex AC and DC drives directly from the control location or while mounted on the drive enclosure. This versatile platform supports both handheld and drive-cover-mounted configurations, making it ideal for commissioning, diagnostics, and routine maintenance in industrial automation environments.
