Allen-Bradley 20-HIM-A6 PowerFlex Interface Module

Allen-Bradley 20-HIM-A6 PowerFlex Interface Module is an enhanced Local Human Interface for PowerFlex 7-class drives, featuring an LCD display and full numeric keypad for on-panel configuration, monitoring, and diagnostics of PowerFlex 753 and 755 drives and their peripherals. It communicates with the host drive via the Drive Peripheral Interface (DPI) protocol, with DPI data rates of 125 KBps or 500 KBps, and draws about 140 mA from a 12 V DC supply provided by the host drive. The module measures 116 x 70 x 16 mm, supports 0 to 50 °C operation, and 5–95% relative humidity (non-condensing); it must not be installed in areas containing volatile or corrosive gases, vapors, or dust, and is housed in a NEMA 1 enclosure. Typical applications include drive commissioning, parameter configuration, and real-time monitoring of PowerFlex 753/755 systems, making it a focused interface for field technicians and control engineers working with PowerFlex drives.
