Fused Field Wire Conversion Module for Modicon B826-032 to 1756-OB32 (Cat 1492-CM800-LD009) Local language (French, Italian, German & Spanish) versions of this document can be downloaded by going to www.ab.com. In the left margin click on Publications Library and Literature Library. In the Search Area (right margin), Search by Catalog Number and in the Search box type in the catalog number of the conversion system component. I. Module Description The 1492-CM800-LD009 conversion module provides field wire signal conversion from a Modicon® B826-032, 20 to 28Vdc, 32-pt output module to a ControLogix 1756-OB32, 10 to 31.2Vdc, 32-pt output module. The conversion module provides the mating connections to the B826-032 swing-arm (terminal block) with the attached field wires. It routes those signals, via its 40-pin connector and a 1492-CABLEZ pre-wired cable to compatible terminals of the 1756-OB32. To maintain the functionality of the B826-032 output module the conversion module provides a mechanical fuse for each of the two power supplies (DC-0+ and DC-1+) on the 1756-OB32 (refer to the Wiring Diagram on page 2). 40-Pin Connector for 1492-CABLEZ Mating Connector for B800 Terminal Block 1492-CM800-LD009 Conversion Module WARNING 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. II. Module Installation The 1492-CM800-LD009 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 Wiring Diagram The following diagram shows the connections from the existing B826-032 swing-arm, through the conversion module, 1492 cable and to the 1756-OB32 output module. The diagram can be used as an aid in possible system troubleshooting. WARNING 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.

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. 1 2 3 4 5 6 7 1756 Chassis Max.
