Overview
The Allen-Bradley 1492-CM1771-LA001 swing-arm conversion module provides a reliable path for converting 1771-IFE single-ended analog I/O to 1756-IF16 ControlLogix I/O. This conversion module allows you to upgrade legacy PLC-5 systems to modern ControlLogix platforms without removing existing swing-arm field connections, eliminating wiring errors and reducing commissioning time.
Key Features
- Converts 1771-IFE and 1771-IFF to 1756-IF16 single-ended current or voltage signals
- Swing-arm edge connector fits directly onto module—no field wire removal required
- Rated for 2 amp per point, 12 amp module maximum
- Operates 0–60°C with 5–95% humidity tolerance
- UL, CSA, CCC, and KC certified for global applications
- Compact design integrates into existing 1756 chassis installations
