Overview
The Allen-Bradley 1492-CM1771-LA003 swing-arm conversion module is a specialized adapter designed to bridge legacy PLC-5 1771-series I/O architecture with ControlLogix 1756-series modules. This conversion module allows the mechanical swing-arm mount from 1771-OFE2 or 1771-OFE1 analog output modules to interface with 1756-OF6CI or 1756-OF6VI target modules, eliminating the need for full panel rewiring during system upgrades.
Key Features
- Enables conversion from 1771-OFE2 to 1756-OF6CI or 1771-OFE1 to 1756-OF6VI
- Maintains existing swing-arm mounting geometry
- Lightweight, compact form factor (0.40 lbs)
- Compatible with Rockwell Automation selection guides and documentation
- Reduces downtime during legacy system migration
- OEM-quality Allen-Bradley construction
