I. Module Description
The 1492-CM800-LD015 conversion module provides field wire signal conversion from a Modicon® B814-108 or
B840-108 , 8-pt relay output to a ControLogix 1756-OX8I , 8-pt relay output module. The conversion module
provides the mating connections to the B814-108 or B840-108 swing-arm (terminal block) with the attached field wires.
It routes those signals, via its 40-pin connector and a 1492-CABLEY pre-wired cable to compatible terminals of the
1756-OX8I. To maintain the fusing functionality of the B814-108 and B840-108 output modules the conversion module
provides a mechanical fuse for each of the 8 converted output points (refer to the Wiring Diagrams on pages 2 and 3).
II. Module Installation
The 1492-CM800-LD015 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 B814-108 and B840-108 swing-arm, through the conversion module, 1492 cable and to the 1756-OX8I output module. The diagrams can be used as an aid in possible system
troubleshooting.

Conversion Module Installation and Application Considerations
The B814-108 relay module resistive current limits versus 1756-OX8I limits are as follows: (NOTE: for switching and inductive
current and voltage ratings, refer to the modules Installation Manual)

a) Current/Point
3A Cont, 2A Switching 960VA or 150W DC 2A @ 30V DC/125V AC
The B814-108 is fused per output point. The 1756-OX8I is NOT fused. The 1492-CM800-LD015 provides a 5x20mm fuse
per 1756-OX8I point. Fuse rating for this configuration is 2 Amps.
The 1492-CABLE003Y current is limited to 2A per pin.
The B814-108 allowed using a circuit board jumper to configure each relay output for N.O. or N.C. operation (N.O. default),
but only one set of field terminals was provided on the module. The 1492-CM800-LD015 conversion module is set for N.O.
relay operation. If the N.C. contact of the 1756-OX8I relay module is required, it may be accessed by modifying the wiring at
the module’s swing-arm (terminal block).
Refer to your B814-108 and 1756-OXI Installation Manual wiring schematics and diagrams. Ensure 1756 output module
ratings are not exceeded. [Reference Doc: 41170-782 (Version 03)]

VIII. 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.
One chassis slot required for the ControlLogix processor or a remote I/O adapter type module.
The footprint and mounting dimensions of the 1492 Conversion Assembly (base plate and cover plate) match those of the
Modicon I/O Housing.
Width dimension includes the 1756 Chassis power supply.
Surplus Chassis width as compared to the 800 I/O Housing is divided equally when mounting it on the Conversion Assembly.
Mounting holes for the 1756 I/O Chassis are pre-drilled and pre-tapped into the Conversion Assembly cover plate.
