I. Module Description
The 1492-CM800-LD009 conversion module provides field wire signal conversion from a Modicon® B826-032, 20 to
28Vdc, 32-pt output module to a ControLogix 1756-OB32, 10 to 31.2Vdc, 32-pt output module. The conversion
module provides the mating connections to the B826-032 swing-arm (terminal block) with the attached field wires. It
routes those signals, via its 40-pin connector and a 1492-CABLEZ pre-wired cable to compatible terminals of the
1756-OB32. To maintain the functionality of the B826-032 output module the conversion module provides a mechani-
cal fuse for each of the two power supplies (DC-0+ and DC-1+) on the 1756-OB32 (refer to the Wiring Diagram on
page 2).
II. Module Installation
The 1492-CM800-LD009 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.
