I. Module Description
The 1492-CM800-LD015 conversion module provides field wire signal conversion from a Modicon® B814-108 or
B840-108 , 8-pt relay output to a ControLogix 1756-OX8I , 8-pt relay output module. The conversion module
provides the mating connections to the B814-108 or B840-108 swing-arm (terminal block) with the attached field wires.
It routes those signals, via its 40-pin connector and a 1492-CABLEY pre-wired cable to compatible terminals of the
1756-OX8I. To maintain the fusing functionality of the B814-108 and B840-108 output modules the conversion module
provides a mechanical fuse for each of the 8 converted output points (refer to the Wiring Diagrams on pages 2 and 3).
II. Module Installation
The 1492-CM800-LD015 conversion module must be installed in a 1492 conversion base-plate and cover-plate assem-
bly. 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
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).

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.
