Product Overview
The Allen-Bradley 20-HIM-C3S is a remote Human Interface Module (HIM) designed for PowerFlex AC drives. It provides an external LCD keypad interface for configuring, monitoring, and controlling drive parameters without opening the electrical cabinet.
It is commonly used with PowerFlex 70, 700, 700H, 700S, 750, and related drive families, especially in industrial automation systems requiring door-mounted or remote operator access.

Function and Working Principle
The 20-HIM-C3S operates as an external operator terminal connected to the drive through DPI communication. It enables:
- Real-time monitoring of drive status and faults
- Editing and configuration of drive parameters
- Local start/stop control (depending on access level)
- Diagnostics and troubleshooting without cabinet access
It essentially extends the drive’s interface to a safer external location.
Role in Industrial Systems
This module is widely used to improve:
- Operator safety (no need to open live electrical panels)
- Maintenance efficiency
- Accessibility of drive control interfaces
- On-site diagnostics and commissioning workflows
It is especially common in process plants and manufacturing systems.
Industrial Applications
- Conveyor systems
- Pumping and water treatment stations
- HVAC drive systems
- Packaging machinery
- Industrial automation lines
Installation Notes
- Connected via DPI cable to PowerFlex drive
- Mounted on panel door or external enclosure surface
- Requires proper shielding and cable routing
- Must match drive firmware and compatibility requirements
Compatible Equipment
- PowerFlex 70 / 700 / 700H / 700S / 700L
- PowerFlex 750 series (depending on system configuration)
- DPI-based Rockwell drive platforms
- Remote HIM bezel kits (such as 20-HIM-B1)
Key Advantages
- Safe remote access to drive control
- Full LCD-based parameter navigation
- Improves commissioning and maintenance speed
- Compatible across multiple PowerFlex 7-class drives
- Reduces need to open electrical cabinets
Limitations
- Requires external cable connection (not wireless or Ethernet-based)
- Depends entirely on drive communication (not standalone control)
- Uses legacy DPI architecture compared to modern Ethernet HMIs
Conclusion
The Allen-Bradley 20-HIM-C3S Human Interface Module is a remote LCD keypad solution that enables safe and convenient control, monitoring, and configuration of PowerFlex drives.
It is widely used in industrial environments where external access to drive parameters and diagnostics is required without opening electrical enclosures.
