Overview
The Allen-Bradley 22-COMM-D Series A is a PowerFlex communication adapter that provides DeviceNet to DSI (Drive Serial Interface) connectivity for industrial AC drive systems. This module bridges DeviceNet networks and PowerFlex drives, enabling real-time control, diagnostics, and data exchange with Rockwell Automation controllers and other DeviceNet-enabled systems.
Key Features
- DeviceNet protocol support with flexible baud rates (125K, 250K, 500K Kbps)
- Supports PowerFlex 4, 40, 40P, 400, 523, and 525 series AC drives
- Single-drive or multi-drive operation (supports up to 5 drives per adapter)
- Node addressing via rotary switches or software configuration
- Three LED status indicators for module and network monitoring
- 20-pin DSI connector and 5-pin DeviceNet connector
- Compact design suitable for tight enclosures
- Mode jumper for multi-drive daisy-chain operation
