I. Module Description

The 1492-CM800-LD004 conversion module provides field wire signal conversion from a Modicon® B806-032, 80 to
130Vac , 32-pt output module to two ControLogix 1756-OA16, 74 to 265Vac , 16-pt output modules. The conver­sion module provides the mating connections to the B806-032 swing-arm (terminal block) with the attached field
wires. It routes those signals, via its two 20-pin connector and two 1492-CABLEX pre-wired cables to compatible
terminals of the two 1756-OA16 modules (refer to the Wiring Diagram on page 2).

II. Module Installation

The 1492-CM800-LD004 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.

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.

Conversion Module Installation and Application Considerations



This configuration uses two (2) 1756-OA16 output modules to replace a single B806-032 output module. This may require the use

of a larger 1756 I/O Chassis. Ensure there is sufficient panel space to allow for this possibility.



The B806-032 module output current limits versus 1756-OA16 limits are as follows:
B806-032 1756-OA16 w/ 1492-CABLE003X
a) Current/Point 1A 0.5A
b) Current/Group 8A 2A
c) Current/Module 16A (32 pts) 4A (16 pts)
d) Surge Current/Pt 15A for 1 cycle 5A for 43ms



The B806-032 module did NOT provide fusing. The 1756-OA16 provides a single fuse per group.

 The 1492-CABLE003X current is limited to 2A per pin.
 Refer to your B806-032 and 1756-OA Installation Manual wiring schematics and diagrams for more details.

Ensure 1756 output

module ratings are not exceeded. [Reference Doc: 41170-753 (Version 03)]

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.
