I. Module Description
The 1492-CM800-LD003 conversion module provides field wire signal conversion from a Modicon® B805-016 or
B853-016, 80 to 130Vac , 16-pt input module to a ControLogix 1756-IA16, 74 to 132Vac , 16-pt input module. The
conversion module provides the mating connections to the B805-016 or B853-016 swing-arm (terminal block) with the
attached field wires. It routes those signals via its 20-pin connector and a 1492-CABLEX pre-wired cable to compatible terminals of the 1756-IA16 (refer to the Wiring Diagram on pages 2 and 3).
II. Module Installation
The 1492-CM800-LD003 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).

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.

IV. Conversion Module Wiring Diagram
The following diagrams show the connections from the existing B805-016 and B853-016 swing-arm, through the conversion module, 1492 cable and to the 1756-IA16 input module. The diagrams can be used as an aid in possible system
troubleshooting.

Conversion Module Installation and Application Considerations
The input delay times for the B805-016 module versus 1756-IA16 module are as follows:
B805-016 1756-IA16
a) Off-to-On Delay 6ms 10ms (plus selectable filter)
b) On-to-Off Delay 18ms 8ms (plus selectable filter)
Refer to your B805-016 and 1756-IA16 Installation Manual wiring schematics and diagrams for more details.

There are several key application considerations and system specifications (bottom of drawing) when
using these components (conversion module, cable and output module). Read and understand these
considerations before installation.
