I. Module Description
The 1492-CM800-LD008 conversion module provides field wire signal conversion from a Modicon® B825-016, 20 to
28Vdc, 16-pt input module to a ControLogix 1756-IB16, 10 to 31.2Vdc, 16-pt input module. The conversion module
provides the mating connections to the B825-016 swing-arm (terminal block) with the attached field wires. It routes
those signals, via its 20-pin connector and a 1492-CABLE
