Allen-Bradley 20-HIM-A6 PowerFlex 7-Class Full Text Keypad

Allen-Bradley 20-HIM-A6 PowerFlex Enhanced LCD Human Interface Module

Product Description

The 20-HIM-A6 (20-HIM-A6) is an Enhanced Human Interface Module (HIM) engineered for the Allen-Bradley PowerFlex 7-Class and 750-Series AC drives. This Series A module represents a significant upgrade over standard numeric interfaces, featuring a multi-line, full-text LCD display that provides descriptive parameter names and real-time diagnostic feedback in plain language.

Designed for versatility, the 20-HIM-A6 (20-HIM-A6) supports the Drive Peripheral Interface (DPI) protocol and is essential for high-level commissioning and maintenance. It includes advanced functionality such as the "CopyCat" feature, which allows users to upload, store, and download complete parameter sets between drives, drastically reducing setup time for multi-drive systems. Whether integrated directly into the drive's cradle or remote-mounted on a NEMA 1 rated panel door, this HIM provides the tactile control and visual clarity required for professional industrial motor control.
