I. Module Description
The 1492-CM800-LA002 conversion module provides field wire signal conversion from a Modicon® B877-111,
analog, 16-channel, single-ended current or voltage input module to a ControLogix 1756-IF16, analog, 16-channel,
single-ended current or voltage input module. The conversion module provides the mating connections to the B877-
111 swing-arm (terminal block) with the attached field wires. It routes those signals, via its 25-pin, D-shell connector
and a 1492-ACABLEUB or 1492-ACABLEUA pre-wired cable to the compatible terminals of the 1756-IF16 (refer
to the Wiring Diagrams on pages 2 and 3).
II. Module Installation
The 1492-CM800-LA002 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
 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. WARNING
