I. Module Description
The 1492-CM1771-LD002 conversion module provides field wire signal conversion from an A-B 1771-IAD, 79 to
138Vac/dc, 16 point input module to a 1756-IH16I, 90 to 146Vdc , 16 point individually isolated input module or a
1771-IMD, 184 to 250Vac or 166 to 230Vdc, 16 point input module to a 1756-IM16I, 159 to 265Vac , 16 point
individually isolated input module. The conversion module provides the mating connector to the 1771-IAD or
1771-IMD module swing-arm/terminal block with the attached field wires. It routes those signals via its 37-pin
connector and a 1492-CONCAB Y pre-wired cable to compatible terminals on the 1756-IH16I or 1756-IM16I
(refer to Wiring Diagrams on page 2 and 3 for details).
II. Module Installation
The 1492-CM1771-LD002 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.
