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-CABLEU 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).
