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-CABLEX 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.

IV. Conversion Module Wiring Diagram

The following diagrams show the connections from the existing B804-116 or B824-016 swing-arm, through the conversion
module, 1492 cable and to the 1756-OA16 or 1756-OB16E output module. The diagrams can be used as an aid in
possible system troubleshooting.

Conversion Module Installation and Application Considerations



The B804-116 module output current limits versus 1756-OA16 limits are as follows:
B804-116 1756-OA16 w/ 1492-CABLE003X
a) Current/Point 2A 0.5A
b Current/Group 6A 2A
b) Current/Module 12A 4A
c) Surge Current/Pt 50A for 1 cycle 5A for 43ms

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.
