Description
The 20-HIM-A6 is an enhanced Human Interface Module (HIM) manufactured by Allen-Bradley, a brand of Rockwell Automation — the world’s leading provider of industrial automation and digital transformation solutions. Designed specifically for PowerFlex 750-Series AC drives and PowerFlex 7-Class drives, the 20-HIM-A6 serves as the primary local operator interface for drive configuration, real-time monitoring, manual motor control, and fault diagnostics. Featuring a multi-line full-text LCD display with backlight, a full numeric keypad, dynamic soft keys, and Drive Peripheral Interface (DPI) communication, the 20-HIM-A6 delivers an intuitive, tactile control experience that dramatically simplifies commissioning and maintenance of industrial motor control systems.
Application Scenarios
In a municipal water treatment plant on the U.S. Gulf Coast, the facility operated dozens of PowerFlex 755 drives controlling pumps, blowers, and agitators across multiple process buildings spread over a 40-acre campus. When a pump drive required on-site adjustment of acceleration ramp time or a quick jog test during mechanical maintenance, technicians previously had to wheel a laptop to the field location, establish a connection, and navigate complex software menus — a process that consumed 20–30 minutes per visit and exposed expensive PCs to wet, corrosive environments.
By equipping every PowerFlex 755 drive with a 20-HIM-A6, the plant transformed its maintenance workflow. The 20-HIM-A6’s full-text LCD eliminated the need to cross-reference numeric parameter codes with thick manuals — technicians could read plain-English parameter names and fault descriptions directly on the display. The dedicated Start, Stop, and Direction keys allowed for safe manual motor testing right at the drive. Most importantly, the 20-HIM-A6’s “CopyCat” capability enabled a single technician to upload a fully tuned parameter set from one drive, walk to a sister pump station 200 meters away, and download the identical configuration into another in under 3 minutes — ensuring perfect consistency across redundant pump trains. This scenario illustrates how the resolves the #1 pain point of motor control maintenance: delivering laptop-grade configuration capability in a rugged, pocket-sized, hot-swappable module that survives harsh industrial environments.
