I. Module Description

The 1492-CM800-LD014 conversion module provides field wire signal conversion from a Modicon® B810-008, 80 to
130Vac , 8-pt, individually isolated, output to a ControLogix 1756-OA16I, 74 to 265Vac , 16-pt, individually
isolated, output module. The conversion module provides the mating connections to the B810-008 swing-arm
(terminal block) with the attached field wires. It routes those signals, via its 40-pin connector and a 1492-CABLE(1)Y
pre-wired cable to compatible terminals of the 1756-OA16I. To maintain the fusing functionality of the B810-008 output
module the conversion module provides a mechanical fuse for each of the 8 converted output points (refer to the
Wiring Diagram on page 2).

II. Module Installation

The 1492-CM800-LD014 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.

Refer to conversion module Specifications Section: Maximum Operating Voltage

1492-CM800-LD014 Conversion Module

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 B810-008 swing-arm, through the conversion module,
1492 cable and to the 1756-OA16I output module. The diagram can be used as an aid in possible system troubleshooting.

Conversion Module Installation and Application Considerations


The B810-008 is an 8 point output module whereas the 1756-OA16I is 16 point. This conversion configuration is selected

because an individually isolated 8 point module is not available in the 1756 I/O line.



The B810-008 module output current limits versus 1756-OA16I limits are as follows:

B810-008 1756-OA16I w/ 1492-CABLE003Y

a) Current/Point 2A 1A
b) Current/Module 12A 4A
c) Surge Current/Pt 50A for 1 cycle 20A for 43ms



The B810-008 is fused per point. The 1756-OA16I is NOT fused. The 1492-CM800-LD014 provides a 5x20mm fuse per

1756-OA16I Group.

Fuse rating for this configuration is 1 Amp.



The 1492-CABLE003Y current is limited to 2A per pin.

 Refer to your B810-008 and 1756-OA16I Installation Manual wiring schematics and diagrams. 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.
