I. Module Description
The 1492-CM800-LD013 conversion module provides field wire signal conversion from a Modicon® B802-008, 80 to
130Vac , 8-pt output module to a ControLogix 1756-OA8E, 74 to 132Vac , 8-pt output module. The conversion
module provides the mating connections to the B802-008 swing-arm (terminal block) with the attached field wires. It
routes those signals, via its 20-pin connector and a 1492-CABLEU pre-wired cable to compatible terminals of the
1756-OA8E module. NOTE: The B802-008 was mechanically fused per group. The 1756-OA8E is electronically fused
per group. Refer to the 1756-OA8E Installation Manual and to the Wiring Diagram on page 2.
II. Module Installation
The 1492-CM800-LD013 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 diagram shows the connections from the existing B802-008 swing-arm, through the conversion module, 1492
cable and to the 1756-OA8E output module. The diagram can be used as an aid in possible system troubleshooting.

Conversion Module Installation and Application Considerations
The B802-008 module output current limits versus 1756-OA8E limits are as follows:
B802-008 1756-OA8E w/ 1492-CABLE003U
a) Current/Point 2A 2A
b) Current/Module 12A 8A@30°C, 4A@60°C
c) Surge Current/Pt 50A for 1 cycle 20A for 43ms
The B802-008 has 4 groups (allowing 4 separate power supplies) and the 1756-OA8E has 2 groups. This module/cable
combination ties Groups 1 & 2 from the B802-008 to Group 0 on the 1756-OA8E and it ties Groups 3 & 4 from the B802-008 to
Group 1 on the 1756-OA8E. Field wiring modification must be made to accommodate this if multiple supplies were used. If 4
supplies were used, 2 must be removed.
The B802-008 provided a single fuse per group. The 1756-OA8E is electronically fused per point. Refer to the 1756-OA8E
Installation Manual for electronic fusing details.
The 1492-CABLE003U current is limited to 2A per pin.
Refer to your B802-008 and 1756-OA8E Installation Manual wiring schematics and diagrams for more details. Ensure 1756
output module ratings are not exceeded.

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.
