Product Overview

The Allen Bradley 20-HIM-A3 provides a robust, local interface for configuring and diagnosing PowerFlex 70 and 700 series AC drives. Equipped with a full numeric keypad and a high-visibility backlit LCD, this Human Interface Module (HIM) streamlines parameter entry and real-time monitoring. It enables engineers to navigate drive menus, manage faults, and duplicate settings across multiple drives using its integrated nonvolatile memory. We supply this unit as 100% Brand New and Original, ensuring high-integrity communication with your drive's HIM port for both handheld and drive-mounted applications.

Engineering Advantages

Rapid Parameter Deployment: The integrated CopyCat function allows users to upload entire parameter sets from one drive and download them into another. This functionality eliminates manual data entry errors and slashes commissioning time during large-scale drive rollouts.
Full Numeric Navigation: Unlike basic HIM units with only arrow keys, the 20-HIM-A3 features a full numeric keypad. This hardware upgrade enables direct value entry, allowing technicians to jump to specific parameter numbers or enter setpoints instantly rather than scrolling through thousands of variables.
Dual-Purpose Versatility: The module supports both direct drive mounting for permanent local control and handheld use for field diagnostics. This versatility ensures that a single 20-HIM-A3 can serve as a permanent HMI for one drive or a mobile troubleshooting tool for an entire plant floor.
Enhanced Fault Visibility: The 7-line LCD displays clear, multi-language fault descriptions instead of cryptic error codes. This immediate access to diagnostic data allows maintenance teams to identify root causes—such as overvoltage or ground faults—without referencing paper manuals.

FAQs

Is the 20-HIM-A3 compatible with the PowerFlex 750-series (753/755)?

No. The 20-HIM-A3 specifically serves the Architecture Class PowerFlex 70 and 700 series. For PowerFlex 753 or 755 drives, you must use the 20-HIM-A6 or newer series HIM modules.

Can I remove the 20-HIM-A3 while the drive is running?

Yes, the 20-HIM-A3 supports hot-plugging. You can connect or disconnect the HIM from the drive’s port while power is applied without interrupting the drive's operation, provided the drive is not configured to require an "HIM Present" interlock for safety.

How does the backlit display improve industrial operations?

Industrial cabinets often sit in dimly lit areas. The backlit LCD ensures that parameters remain legible in dark environments, reducing the risk of accidental misconfiguration during emergency night-shift maintenance.

Do I need a battery for the nonvolatile memory?

No. The 20-HIM-A3 stores its CopyCat data in nonvolatile flash memory. It retains all uploaded parameter sets even when disconnected from the drive, making it a reliable physical backup device for your drive configurations.
