Genuine Allen-Bradley 20-HIM-A3 - Industrial Automation Part

Allen-Bradley 20-HIM-A3 Human Interface Module – PowerFlex HIM

Description

Allen-Bradley 20-HIM-A3 Human Interface Module – PowerFlex Human Interface Module (HIM)

Imagine a critical production line halted because an operator cannot access drive parameters, monitor fault codes, or initiate a controlled stop — all because the drive’s interface is buried inside a locked electrical cabinet. Without a reliable Human Interface Module, your PowerFlex drive becomes a black box: inaccessible, unmonitorable, and impossible to commission efficiently. Downtime accumulates, troubleshooting drags on, and production losses mount by the minute. The Allen-Bradley 20-HIM-A3 eliminates this vulnerability entirely, placing full drive control and diagnostics directly in the operator’s hands.

The 20-HIM-A3 is Allen-Bradley’s full-featured remote-mount Human Interface Module designed specifically for the PowerFlex family of AC drives — one of the most widely deployed variable frequency drive platforms in global industrial automation. Within the PowerFlex HIM lineup, the 20-HIM-A3 occupies the premium tier, offering a complete alphanumeric display, full numeric keypad, and remote-mount capability via a standard CAT5 cable up to 10 meters. It is the preferred interface solution for OEMs, system integrators, and end-users operating PowerFlex 4, 40, 400, 70, 700, 750, and related series drives across manufacturing, water/wastewater, HVAC, and process industries worldwide.
