I. Module Description
The 1492-CM800-LD002 conversion module provides field wire signal conversion from a Modicon® B804-116, 80 to
130Vac , 16-pt output module to a ControLogix 1756-OA16, 74 to 265Vac , 16-pt output module or a B824-016,
20 to 28Vdc, 16-pt output module to a 1756-OB16E, 10-31.2Vdc, 16-pt electronically fused output module. The
conversion module provides the mating connections to the B804-116 or B824-016 swing-arm (terminal block) with its
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-OA16 or 1756-OB16E (refer to the Wiring Diagrams on pages 2 and 3 for details).
II. Module Installation
The 1492-CM800-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.
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.

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. In addition, refer to the current draw requirements of the existing
loads for this configuration to ensure they are within the current ratings of the 1756 output module.

Conversion Module Installation and Application Considerations
The B824-016 module output current limits versus 1756-OB16E limits are as follows:
B824-016 1756-OB16E w/ 1492-CABLE003X
a) Current/Point 2A 1A
b) Current/Group 6A 2A
c) Current/Module 12A 4A
d) Surge Current/Pt 5A for 10ms 2A for 10ms
The B824-016 provided a single mechanical fuse per group. The 1756-OB16E is electronically fused per group. Refer to the
1756-OB16E Installation Manual for electronic fusing details.
The 1492-CABLE003X current is limited to 2A per pin.
Refer to your B824-016 and 1756-OB16E Installation Manual wiring schematics and diagrams for more details.
Ensure 1756
output module ratings are not exceeded.

(Operating specifications are when installedin the Conversion System base / cover-plate assembly)
VI. Appendix A - 800 Housing to 1756 Chassis Conversion System Selection Process
1) Determine the number of 800 I/O modules actually used in the 800 I/O Housing to be converted to 1756 I/O.
2) Review the data in Column 5 from the below table, and select a 1756 I/O Chassis which meets your conversion
needs from Step 1. Ensure the information from the I/O Conversion module table is reviewed first since in some
cases, two 1756 modules are needed to replace one 800 I/O module.
3) Once the 1756 Chassis is selected, refer to Column 7 and select the Conversion Assembly.
One chassis slot required for the ControlLogix processor or a remote I/O adapter type module.
The footprint and mounting dimensions of the 1492 Conversion Assembly (base plate and cover plate) match those of the
Modicon I/O Housing.
Width dimension includes the 1756 Chassis power supply.
Surplus Chassis width as compared to the 800 I/O Housing is divided equally when mounting it on the Conversion Assembly.
Mounting holes for the 1756 I/O Chassis are pre-drilled and pre-tapped into the Conversion Assembly cover-plate.
