I. Module Description
The 1492-CM800-LA003 conversion module provides field wire signal conversion from a Modicon® B872-100,
analog, 4-channel, individually isolated current output module to a ControLogix 1756-OF6CI, analog, 6-channel,
individually isolated current output module. The conversion module provides the mating connections to the B872-100
swing-arm (terminal block) with the attached field wires. It routes those signals, via its 25-pin, D-shell connector and
a 1492-ACABLEY pre-wired cable to the compatible terminals of the 1756-OF6CI (refer to the Wiring Diagram on
page 2).
II. Module Installation
The 1492-CM800-LA003 conversion module must be installed in a 1492 conversion 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
 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).
