Allen-Bradley 1492-CM1771-LD006 Swing Arm Conversion Module

Allen-Bradley 1492-CM1771-LD006 Swing-Arm Conversion Module is a field-wire signal conversion device that bridges legacy PLC-5 swing-arm I/O to the 1756 ControlLogix/CompactLogix I/O ecosystem, enabling migration of an existing 1771 swing-arm network to modern 1756 I/O without replacing every I/O point. Specifically, it supports conversion from 1771-OAD swing-arms to 1756-OA16 and from 1771-OBD swing-arms to 1756-OB16E, allowing the original field wiring to connect to the corresponding 1756 I/O modules. As part of Allen-Bradley’s 1492 Field Wiring Conversion Modules family, the LD006 unit interfaces the swing-arm assembly with a 1492 conversion cable to route signals to the 1756 architecture. This makes it a practical option for customers migrating PLC-5 installations to ControlLogix/CompactLogix platforms, preserving wiring layouts while updating the control system. The component is identified by the part number 1492-CM1771-LD006 and is designed for use in migration projects from PLC-5 swing-arm I/O to 1756 I/O.
