Overview
The Allen-Bradley 22-COMM-D /A is a PowerFlex DeviceNet adapter designed for seamless integration of PowerFlex drives into industrial DeviceNet networks. This communication module converts DeviceNet signals to Drive Serial Interface (DSI) protocol, enabling remote monitoring, control, and diagnostics of PowerFlex AC drives in manufacturing and process automation environments.
Key Features
- DeviceNet network communication with support for 125/250/500 Kbps baud rates
- Compatible with PowerFlex 4, 40, 40P, 400, 523, and 525 series drives
- Node address selection via rotary switches for easy configuration
- Three (3) LED status indicators for module and network diagnostics
- Supports single-drive and multi-drive daisy-chain operations
- Explicit messaging enabled for advanced diagnostic and control functions
- Automatic Device Replacement (ADR) support for network fault tolerance
- Compact design suitable for panel or internal drive mounting
