I. Module Description
The 1492-CM800-LD001 conversion module provides field wire signal conversion from a Modicon® B802-008, 80 to
130Vac , 8-pt output module to a ControLogix 1756-OA8, 74 to 265Vac , 8-pt output module. The conversion
module provides the mating connections to the B802-008 swing-arm (terminal block) with the attached field wires. It
routes those signals, via its 20-pin connector and a 1492-CABLEU pre-wired cable to the compatible terminals of
the 1756-OA8. To maintain the functionality of the B802-008 output module the conversion module provides a
mechanical fuse for each of the two power sources (L1-0 and L1-1) on the 1756-OA8 (refer to the Wiring Diagram and
Fuse Installation and Removal sections for details).
II. Module Installation
The 1492-CM800-LD001 conversion module must be installed in a 1492 conversion system base-plate and cover-
plate assembly. The installation of the module into the assembly is explained in the Installation Manual that ships with
the conversion assembly. For a list of compatible assemblies refer to Appendix A
III. Conversion Module Compatibility Matrix
De-energize and lockout any and all power to all I/O field devices connected to the Modicon 800 I/O
housing, and the power to the 800 I/O housing itself. Ensure all power is de-energized and locked out
to any device in the control cabinet where the conversion is to be performed. Ensure work is
performed by qualified personnel. WARNING
 This is the cable length in meters and tenths of meters (e.g. 015 = 1.5 meters). Recommended
cable length is 003 (00.3 meters).
